Nalgene® Reusable Vacuum Filter Holders with Receiver

Nalgene® reusable plastic filter holders eliminate the need for a manifold or even breakable glass vacuum filtering flask. The integral bottom filtrate receiver bottle is transparent with molded-in graduations for liquid volume level visual verification. These reusable vacuum fillter holders accept 47mm membrane filters. Two side-arms allow connection to vacuum line which also allow the incorporation of a syringe filter between the vacuum line and the filter holder unit. The vacuum tubing adapter can be stuffed with cotton for sterile venting during autoclaving; accepts 6 to 8mm (1/4 to 5/16 inch) inner diameter vacuum tubing. Cover allows convenient storage of sterile filtrate. Nalgene 300 series.
