Many biological preparations begin with extractions that require coarse filtration to remove cellular debris. But bulk filtration using cheesecloth absorbs lots of the extraction fluid, while membranes quickly clog.

BioPrepNylon produces rapid bulk filtration at extraordinary flow rates. BioPrepNylon is loosely placed in a sieve holder to form a funnel. The sample is placed in the funnel, allowed to drain, and the layers of the BioPrepNylon are gently pressed together to collect all of the extraction liquid.

• Consists of very fine nylon filaments woven into a matrix with 50 micron pores.
• A pure nylon product without detergents, dyes, or salts. Can be used directly with biologicals.
• As BioPrepNylon does not wet, significantly greater quantities of the extraction liquid are recovered compared to any other method.
• BioPrepNylon does not bind proteins, so no loss of your valuable sample will occur.
• Compatible with the salts, buffers, and solvents used in biological research. Autoclavable.
• Extraordinary cost effective compared to other bulk filtration methods. High tensile strength. Can be repeatedly washed and reused.
