Choosing the Right Adam Balance | Adam Equipment | Greyhound Chromatography

Choosing the right Adam lab balance

Lab balances are expensive investments for labs purchasing them. But with so many options available, it can be difficult to pick the instrument that best suits your needs. In this post, we’ll look at the deciding factors that can help you choose which weighing device to buy for your lab.

Does a higher price tag equal a better balance?

Not always. Brand can be a factor; some balances are very similar, but the branding will add some costs. The higher price can also be due to specific higher-end features such as Bluetooth connection or a statistics mode. These features might be unnecessary or not worth the price. Capacity and readability also affect the price tag; even within the same product range, the models with higher precision tend to be more expensive.

What are you weighing?

The first step of picking the right balance is to examine what you’ll be weighing, and what for. This will help determine capacity and readability. What will you be weighing most often? How much of it will you weigh? You should also consider the size of the samples. Make sure the balance’s weighing pan is large enough to accommodate them. Weighing larger items usually requires a higher capacity. Don’t forget that beakers or containers count as part of the total weight.

It might be tempting to buy the most precise balance available for your budget. Don’t. The more precise the balance, the more factors such as vibrations, static electricity or air currents affect it. If you don’t need a readability of 0.001mg, you’ll just make it more difficult for yourself to use the balance.

Adam Equipment Precision Balances

Precision Balances are better for field experiments or quality testing, since they tend to feature a higher capacity and sturdier construction. They’re quite precise but can still be moved around or used in less than ideal conditions.

To weigh very fine samples (for pharmaceutical applications, for example), analytical or semi-micro balances are the way to go. They’re meant to be used in a designated workspace in regulated environments. They’re acutely precise and extremely sensitive to the smallest changes. If you weigh fine powders, a draft shield can help prevent the sample from being affected by the environment.

All lab balances should feature high repeatability; being able to replicate an experiment and obtain the same results is paramount in science.

Adam Equipment Analytical Balances

Which features and functions are important in a lab balance?

Once you’ve figured out just how precise your balance should be, you can start considering what the balance should be able to do. You can separate them into essential features (absolutely needed to do your job) and non-essential yet convenient (for example, a high-resolution display).

A highly visible display is important, since you’ll spend a lot of time looking at and recording results. Even when balances are connected to computers and results are automatically transmitted, it’s important to clearly view results. It can also be useful to navigate through menus and databases. If the balance has a touchscreen, make sure you can still use it wearing latex gloves.

Balances feature a wide variety of functions, from counting to percentage weighing or statistics. Chemists might need a formulation function, whereas a quality control lab could want percentage weighing function.

Balance display zoom

GLP Printouts and formatting are essential. Make sure the balance will output the data you need for your lab’s records. Balances should also be able to connect to LIMS and other lab management systems, as well as transfer results to applications such as Excel.

Most modern lab instruments connect to computers and/or printers. Balances usually have a standard RS-232 connection. It might be worth paying extra for a USB slot if you use USB connectors or flash drives often. Some balances also offer wireless connection capabilities, but they’re usually more expensive.

The balance’s construction is important too. If you weigh certain chemicals, it might be necessary to have a balance with a weighing pan made of non-corrosive metal. A field balance should be very sturdy, and spill-resistant housing can be useful in busy labs where liquids are frequently weighed. Most importantly, a balance should be easy to clean. Some balance feature removable weighing pans to help during routine maintenance.

Which accessories do I need for my lab balance?

Accessories can improve a balance’s functionality or fulfill specific functions. Printers can be useful for record-keeping. Cables transfer information to other devices. Ionizers help reduce the impact of static electricity on your balance’s results. An anti-vibration table can be set up to create a dedicated workstation for your balance, and to help prevent vibrations from interfering with the balance’s operation. Use a carrying case to protect the balance during transportation.

Accessories

Desity Kits could be worth purchasing for engineering labs. Make sure you buy a kit that fits your balance. Some lab balances have security functions like a lock and cable slot, or password protection, which can be useful to prevent the balance from being moved or used by unauthorized users. Software like AdamDU simplify data collection and analysis.

What is internal calibration and does my balance need it?

Internal calibration is quite practical but more expensive. It’s usually quicker than external calibration, and some balances can even self-calibrate if they detect ambient changes. How often must you calibrate your balance? It could be worth paying extra for a speedier calibration process, or to perform automatic calibration outside of working hours, especially if the balance is exposed to varying conditions. If your lab has dedicated personnel and a calibration station, external calibration could work for you. Don’t forget that external calibration also requires a calibration kit.

How to Select the Right Laboratory Balance | Adam Equipment | Greyhound Chromatography

How to Select the Right Laboratory Balance

A balance is an integral component of lab work, and choosing the correct equipment is essential to obtaining efficient performance and accurate results. There are many considerations in selecting the right lab balance for the job.

When it’s time to purchase a new balance, the first step is to think about the types of applications to be performed. In addition to weighing, will you require your balance to include built-in functions such as checkweighing or formulation? Where will the balance be used – in a lab or in the field? Will you need to connect it to other equipment?

The second step is to determine the readability your balance will need. Readability is the smallest division a balance can display. Your application likely has a requirement for the level of precision in results. If you are weighing chemicals to the nearest 10mg (0.01g), a balance with readability of 0.001 is recommended.

Next, you’ll need to know the capacity required to complete daily tasks. Capacity is the maximum weight the balance can weigh. When calculating capacity, remember to include the weight of any containers you might use.

Highland Portable Precision Balance

Most balances are capable of weighing in different units. Certain applications require specific weighing units. For example, scientific laboratory applications typically require grams and milligrams, jewelry often requires carats. The fourth step is to make a note of the units of measure necessary for your task.

Step five is to determine the pan size. The weighing pan must be large enough to accommodate the items being weighed, along with the container that will be holding them during weighing. The balance location also can play a part in choosing a pan size; space restrictions might mean opting for a smaller platform.

Finally, you should also contemplate the need for additional features:

  • Do you have a preference for internal or external calibration?
  • Do you need to perform below-balance weighing?
  • Will you be weighing living, moving animals – is a dynamic weighing function important?
  • To collect and record data, would a USB or RS-232 connection help?
  • Does your balance need to calculate specific gravity? Some balances do this automatically.
  • Will you be working with or weighing any substances or items that might warrant consideration between all-metal or plastic housing?
  • Are there any workplace issues requiring lockdown capability for your device?

Solis & Equinox Balances

Choosing the right balance is an investment; the right tool for the job can improve efficiency, reduce waste, and even same money on the long run. Buying the wrong balance mean sacrificing precision and accuracy; it can be a costly mistake. Still not sure which balance is right for you?

The main source of particle contamination in HPLC columns originate in the sample to be analysed. Therefore, the final preparation step prior to sample injection into the HPLC instrument is to remove any small particulates from the sample by filtration. Removal of the solid materials is very important as they can interfere with the compound of interest and easily clog up the column being used. This will inevitably have a detrimental effect on the performance of the column, i.e. back pressure, peak size, retention time, peak shape. Severe contamination can lead to the column being irreversibly blocked and therefore having to be replaced. Other costs can include instrument downtime, and the loss of valuable samples.

Sample Types

Samples differ in a variety of ways, they may be heavily loaded with fine or coarse particulates, dissolved in aqueous or organic solvents with varying viscosities. To facilitate the most appropriate sample preparation result, filters should be optimised to match the particular requirements of each kind of sample being injected.

Standard Samples

A matrix of 5-10mL is the most common sample volume, with low viscosity, low particle contamination and dissolved in either an organic or an aqueous solvent. Greyhound Q-Fil Regenerated Cellulose Syringe Filters are an excellent choice for such samples. Their inert housing manufactured from high density medical grade virgin polypropylene, complete with the integrated Regenerated Cellulose (RC) membrane has a high chemical resistance against the most common HPLC solvents and is very suitable for aqueous samples. Every batch is HPLC-tested for low extractables. Whilst 0.45µm is the most commonly used membrane porosity, the 0.22µm membrane provides improved purity when using capillary columns or HPLC packings with a particle size of 3µm or less

Demanding Samples

More difficult samples which contain high loads of particulates, high viscosity or unusually high volumes place additional challenges on the user when preparing samples for HPLC analysis. The particles have a tendency to block the filter, high viscosities will decrease the flow rate and high volumes increase the time required to complete the filtration process. These challenges often result in the user applying a greater degree of manual pressure to the process and potentially exceeding the maximum pressure limit of the filter with a subsequent risk of bursting the housing. As a result, the sample will be lost and a potential safety risk can arise if corrosive solvents or harmful chemicals are being filtered. To assist in overcoming these challenges, the use of Q-Fil Syringe Filters with a built in Glass Microfiber pre-filter are recommended. The pre-filter removes the larger particulates from the sample leaving only the smaller particulates to be filtered by the membrane. These filters increase the flow rate through the unit resulting in a higher volume of sample to be filtered and less pressure being required by the user.

Small Volume Samples

Smaller volume samples are often valuable and require special attention. Any loss of the analyte due to adsorption by the filter membrane or housing or a large dead volume can have a detrimental effect on the analysis. Smaller filters of 13mm and 4mm diameter decrease the dead volume to less than 25uL and 8uL respectively making them ideal for smaller volume samples.

Summary

Sample filtration is an important factor in ensuring that HPLC analysis is achieved in an efficient and cost-effective way. The extensive range of Q-Fil Syringe Filters have been developed to meet the demands of the analyst and the different sample matrices being used and without losing any of the important sample.

Quality is an Important Factor

Greyhound ensures that every batch of filters is manufactured and tested in accordance with strict ISO 9001:2000 quality procedures.

Greyhound ensures that each batch is checked prior to release for:

  •  External Dimensions
  •  Bubble Point
  • Water Flow Rate
  • UV Extractables
  • Burst Pressure and compliance - Filter Integrity.

Choosing a filter on price against quality is not cost effective in the long run.  Although higher spec filters may seem expensive it is false economy to choose cheaper filters as their fail rate is much higher, causing delays in the laboratory.

Q-Fil Syringe Filters

How to choose the right syringe filter for your application

  •    Choose the size of filter based on the volume of sample to be filtered
  •    Choose the filters porosity based on the size of the potential particulates in the sample. It is important to be aware that the finer the porosity of the     membrane the greater the pressure will be required to pass the sample through the filter. A sample containing large quantities of particulates is best filtered using a filter with a built-in glass microfiber pre-filter
  •    Choose the type of membrane based on the solvent being filtered

 Greyhound Syringe Filter

 

Pore Sizes

Q-Fil Syringe Filters are available in 0.22µm and 0.45µm pore sizes, (other pore sizes are available on request). The 0.22µm filters remove the smallest particulates whilst the 0.45µm filters are designed to remove particulates which would be detrimental to most analytical columns.

Pre-filters have a glass microfiber membrane which is chemically inert and resists most solvents. Q-Fil glass microfiber pre-filters are recommended for removing large particulates from the sample and are ideal for dissolution tests.

 Syringe Filters with Glass Microfiber Pre-Filter 

  • The glass microfiber pre-filter is mounted before the microporous filter membrane, eliminating the need for a pre-filtration step, minimising sample loss and prolonging the life of the filter membrane
  • These filters have the same high-quality filter membranes and polypropylene housings as our other Q-Fil Syringe Filters, but include a Glass Microfiber (GMF) membrane used as a pre-filter
  • Flow rates are increased and the filtrate volume is significantly greater when compared to filters without pre-filters
  • Regenerated Cellulose membrane filters with the GMF membrane incorporated as a pre-filter, are particularly useful for tissue culture media filtration, as well as for general biological sample filtration
  • These filters are ideal for general laboratory filtration of samples which contain excessive amounts of particulates
  • The glass microfiber pre-filter removes the large particulates and prevents premature clogging of the filter membrane
