Unique Design Provides Analytical Advantages The exclusive two-piece design of the BAS Microfilter lets you do many of your sample manipulations in one device. Sample transfers may be minimized and glassware use is reduced. Precision improves.

Filter Extremely Small Volumes With Virtually No Sample Loss When you're working with only a few nanograms of material dispersed in microliter volumes, the loss of any analyte during filtration can spell doom for the overall assay as well as waste manhours and costly reagents. And poorly filtered samples can do lethal damage to expensive, sensitive chromatographs. The new Microfilter from Bioanalytical Systems removes suspended matter in extremely small samples with nearly total recovery of the fluid. Unlike conventional syringe attachments, Microfilters avoid sample loss by eliminating expansive dead spaces.

Microfilters are convenient and inexpensive to use. Replacement filter membranes are available in a wide range of pore diameters and materials for use with nearly any solvent. Except for the membrane, Microfilters are completely reuseable. Operation is Simple 1. Place the filter membrane in the Microfilter. 2. Pour in sample. 3. Centrifuge briefly. After spending all that time at the bench, why trust your samples to anything else? Write or call today for more information.
