Product Description
Screwing hot caps down after a liquid autoclave cycle is slow and exposes staff to burns. This bottle and push-on cap system self-vents during sterilization and seals as it cools, removing the manual closure step and lowering contamination risk.
This listing is for DURAN catalog number 219946305: Autoclave Bottle, Clear, 2000 mL, Case of 10. Bottles are made of borosilicate glass 3.3 with a 45 mm tapered neck designed for a green, natural rubber push-on cap. The system is autoclavable at 121 C with slow exhaust, and caps can be reused for up to five cycles. Bottles carry graduations and come in 500, 1000 and 2000 mL, with or without caps; replacement caps are sold separately. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
