Product Description
Skip the open-cap step entirely: these flat-bottom PETG Erlenmeyer flasks ship with a bi-directional transfer cap already installed, so media additions and harvests run through a closed, sterile line. They are a clean fit for single-use workflows where every transfer must stay aseptic.
This listing is for NEST catalog number CA1021-AZC050A: 500 mL PETG Erlenmeyer Flask, Bi-Directional Transfer Cap, 50 cm TPE Tube, 1/8" ID x 1/4" OD, Heat Sealed, Case of 4 (4 x 1). The clear PETG flask is paired with a cap carrying a 50 cm TPE tube (1/8" ID x 1/4" OD) with a heat-sealed end for aseptic welding and a 0.22 µm vent filter with 13.8 cm² of membrane area. Cap and connectors are molded as one piece to limit leakage and residue. Each assembly is E-beam sterilized to SAL 10^-6 and produced under cGMP in an ISO 13485 facility. LIGHT LABS carries the full NEST Scientific catalog with knowledgeable support when you need it.
