Product Description
Move media and cell suspensions in and out of large shake flasks without ever opening them to room air. These 3L wide-mouth systems pair a pre-assembled transfer cap with tubing so feeds, harvests and inoculations run as closed, aseptic transfers, either with a ready-to-use high efficiency flask or as replacement caps for flasks you already stock.
This listing is for NEST catalog number C10333-DZC050B: Inverted Transfer Cap for 3L Wide-Mouth Erlenmeyer Flask, TPE Tube 1/4" ID x 7/16" OD, Sterile, Case of 4 (4 x 1). Each cap is a one-piece molded assembly with integrated connectors, which cuts down on leak points and media hold-up, and it carries a 0.22 µm vent filter for gas exchange during culture. Tubing is TPE or silicone in several ID/OD sizes, with select versions ending in a CPC connector or sampling nozzle. Every unit is supplied sterile and individually packaged, with bi-directional, multifunctional and inverted (gravity-drain) cap styles available. LIGHT LABS carries the full NEST Scientific catalog with knowledgeable support when you need it.
