Whatman is the leading name in filtration and fine partile omission. Don't be fooled by cheaper knock-off brands. This nylon membrane filter is ideal for the quick, efficient filtration of samples up to 100 ml volume. It is produced from pigment-free polypropylene and has standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated). Options include a sterile, medical-grade blister pack for critical applications and a special tube tip outlet that allows the sample to be accurately dispensed into a micro-vial, eliminating air lock. Retention: 0.45µm or .20µm.
