Product Description
During freeze-drying, stoppers must sit partially open to let vapor escape and then seat fully at the end of the cycle. These two-leg lyophilization stoppers do just that, and their leg design reduces the chance of stoppers sticking together in the hopper.
This listing is for Kimble catalog number 73828-13: Gray Butyl Two-Leg Lyophilization Stopper, 13 mm, Case of 1,000. Stoppers are made of high-grade gray butyl rubber in a lyophilization style with two legs. They are designed for aluminum seal finish vials in 13 mm and 20 mm sizes and are sealed with crimped aluminum caps after stoppering. Packed 1000 per case. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
