Product Description
Build a fully closed shake-flask workflow, from media fill to harvest: this range covers 2L, 3L and 5L high-efficiency Erlenmeyer flasks supplied with a transfer cap already installed, plus stand-alone 2L and 3L transfer caps to fit flasks you already stock. Liquid moves through sterile tubing by peristaltic pump or gravity, so the vessel never has to be opened.
This listing is for NEST catalog number C10223-BZC050A: 3L High Efficiency Erlenmeyer Flask, Bi-Directional Transfer Cap, 50 cm TPE Tube, 1/4" ID x 3/8" OD, Sterile, Case of 4 (4 x 1). Caps come in bi-directional (white), multifunctional (blue, some with a sampling nozzle) and inverted (green) styles, with TPE or silicone tubing in several diameters and either heat-sealed ends or CPC-style quick connectors with sealing caps. A one-piece cap and connector design reduces leak points and media residue, and a built-in 0.22 µm vent filter supports gas exchange. Every assembly is individually packaged, E-beam sterilized to SAL 10^-6 and certified free of endotoxins and animal-origin components. Add it to your LIGHT LABS order and keep your bench stocked with genuine NEST consumables.
Key Features
- Closed System Transfer – Fill, feed and harvest without uncapping the flask
