Product Description
When samples need room to mix, the 2.0 mL round-bottom microtube gives extra volume and an easy shape for resuspension and bead homogenization. A locking cap keeps lids shut through vortexing and heating. Tubes are available non-sterile in bulk or sterile in bags of 50.
This listing is for NEST catalog number 620611: 2.0 mL Microcentrifuge Tube, Clear, Round Bottom, Lock Cap, Sterile, 50 per Bag, Case of 4,000 (10 Packs x 400). Each tube is molded from additive-free USP Class VI polypropylene and is rated from -80°C to 121°C. Production follows cGMP in ISO 13485:2016 and ISO 9001 facilities with ISO 7 cleanroom molding, and lots are tested free of pyrogens, cytotoxins, DNase, RNase, DNA and BSE/TSE. LIGHT LABS carries the full NEST Scientific catalog with knowledgeable support when you need it.
