Syringe filters are commonly used to pre-filter samples with volumes ranging from 1-100 mL because they can easily attach to any syringe. The sample is pushed through the syringe filter membrane which traps particulates, resulting in a contaminant and particulate free sample.

tighten and staffs are “right sized” the workload of researchers increase. This directly relates to the consideration of which type of homogenizer to use in sample preparation. There are many tools available, but many are designs that have been unchanged in half a century and designed for scientists who might be processing a
Syringe filters with CA (cellulose acetate) or PES (polyether sulfone) membranes are ideal for sterile filtration of buffers, tissue culture media or additives, and other biologicals. The PES membrane offers high flow rates. RC and PTFE hydrophilic type offer the best chemical resistence for both aqueous solutions and solvents.

3. Choose the right filter disc diameter. Utilize the table to see what filter size is recommended to filter your sample volume. Diameter of Membrane. Volume of Solution. 3 mm. < 1 mL. 13 mm. < 5 mL.
μg/L (ppb) to ng/L (ppt) levels. The concentrator column is typically placed on the injection valve in place of the sample loop, just before the analytical column. Sample is first collected on the concentrator column, which strips and retains the ions as the sample flows to waste.
