Product Description
Multiply your growth area without multiplying shelf space. A single 3-layer flask does the work of three 175 cm² flasks, and the 5-layer version replaces five, cutting handling steps and incubator footprint during scale-up.
This listing is for NEST catalog number 731301: 3-Layer Cell Culture Flask, 525 cm², Straight Neck, Plug Seal Cap, TC-Treated, Sterile, Case of 12 (12 x 1). Layers are ultrasonically welded from USP Class VI polystyrene with no adhesives, so there are no extractables or leachables from glue, and caps are polyethylene. Every flask is plasma TC-treated, individually wrapped in a sterile bag, e-beam sterilized to SAL 10^-6 and certified free of pyrogens, cytotoxins, DNase/RNase, DNA, BSE/TSE and animal-derived components. Frosted writing areas and printed lot numbers aid identification and traceability. Order it from LIGHT LABS alongside the rest of your NEST plastics and consumables.
