Qty. 1,000 stoppers/carton

4040/40 Gray LyoTec® Westar® Select B2-04 ready-to-use stoppers are reliable container closures for your lyophilized drug product. The igloo design prevents twinning and provides stability on the vial in the vented position. FluroTec® film applied to the top of the stopper averts sticking to the lyo shelves while B2-coating provides lubricity to prevent clumping and to allow for smooth tracking with virtually no free silicone oil. Designed with ultra-low extractables to protect product quality while supporting drug compatibility and low particulate levels, this stopper has been steam sterilized and dried for ready-to-use convenience with a residual moisture specification of 0.2% water.
