Product Description
Retrofit the flasks already on your shaker for closed, aseptic liquid handling: these transfer cap assemblies screw onto 3L and 5L high-efficiency Erlenmeyer flasks and turn them into closed vessels for filling, feeding and harvest. When transfer is complete, the cap can be swapped back for a standard vent cap for continued culture.
This listing is for NEST catalog number C10223-FDC050B: Bi-Directional Transfer Cap for 3L High Efficiency Flask, 50 cm Silicone Tube, 1/4" ID x 3/8" OD, Female CPC, Case of 4 (4 x 1). Choose bi-directional (white) caps for pump-driven fill and drain, multifunctional (blue) caps including a sampling nozzle option, or inverted (green) caps for gravity transfer. Tubing is TPE or silicone in several diameters, finished with a heat seal or CPC-style male or female connector with sealing cap, and each cap carries a 0.22 µm vent filter. One-piece molded caps reduce leaks and residue, and every assembly is individually packed, E-beam sterilized to SAL 10^-6 and certified endotoxin-free with no animal-origin components. LIGHT LABS carries the full NEST Scientific catalog with knowledgeable support when you need it.
