Product Description
Swap in a fresh, sterile filter closure whenever a culture needs it: these replacement vent caps let shaker flasks breathe while keeping microorganisms out. They are the easy fix for autoclaved and reused polycarbonate flasks, since the original vent caps are not autoclavable.
This listing is for NEST catalog number 787913: Vent Cap with 0.22 µm Filter for 3L Wide Mouth and 5L High Efficiency Erlenmeyer Flasks, Sterile, Case of 20 (20 x 1). Each cap is molded from USP Class VI polypropylene and fitted with a 0.22 µm hydrophobic filter that blocks the entry and exit of microorganisms while allowing gas exchange. Caps are E-beam sterilized to SAL 10^-6 and made in a cGMP, ISO 13485 facility, with lot testing for pyrogens, cytotoxins, DNase/RNase, DNA and BSE/TSE. Add it to your LIGHT LABS order and keep your bench stocked with genuine NEST consumables.
