Product Description
One cap, two jobs: these culture tubes let you switch between aerobic and anaerobic growth simply by how far the plug cap is pressed in. Pick 5 mL (12 x 75 mm) or 14 mL (17 x 100 mm) tubes in polypropylene or polystyrene, pre-capped and sterile, or uncapped with caps purchased separately.
This listing is for MTC Bio catalog number T8309, the Two-Position Cap for 12 x 75 mm Culture Tubes. Polypropylene tubes handle -190 to +120°C and centrifugation up to 4,000 x g, while crystal-clear polystyrene tubes are rated for 0 to 70°C and up to 2,000 x g. Caps are soft polyethylene that sit loosely in the first position for aerobic culture or snap down to a second position for an airtight, liquidtight seal. Sterile capped tubes are certified RNase, DNase, pyrogen and cytotoxin free and fit standard lab racks and equipment; a 7 mL, 15 x 60 mm polypropylene tube with attached cap is also available. LIGHT LABS stocks MTC Bio consumables and ships quickly from Englewood, Colorado.
