20mm White Sleeve Stopper, Isoprene Rubber, 14x20mm, Pack of 50
20mm (14x20mm) White Isoprene Rubber Sleeve Stopper.
Can be used on chemistry glassware or serum vials with a 13x20mm finish.
When using on serum vials, you should first moisten the smaller end of the sleeve
stopper and then twist the sleeve stopper down into the serum vial. After fully inserted,
unravel the wider end of the stopper down around the rim and neck of the vial. A very secure,
airtight seal is created without the need for specialty crimpers and seals.
