Dri-Gauze Filter Cap Linings (300ml Flask) – 5 Pack
- Includes five dri-gauze filter cap linings to accommodate a 300ml flask.
The Dri-Gauze filter is 0.22 micron and constructed of nitrocellulose. Each filter can be used 10 – 12 times. The Dri-Gauze filters can be autoclaved in the cap.
To replace the filter lining in the cap assembly, simply pinch the flanges of the inner-closure shell until they snap loose. Then, pull apart and remove used lining. Replace the lining by sandwiching it between two parts of the cap and snap the cap back together. When reassembling the cap, ensure the flanges from the inner piece snap into the mated grooves in the outer piece. This will ensure the cap assembly stays together during use.
