Our USA Glass Stoppers are made of premium glass.
We have 4 sizes to meet your laboratory needs.
We ship all glassware products with additional care, but sometimes they arrive broken. If glassware arrives broken, please contact us within 3 days of receiving your product and we will either send you a brand new piece or send you a refund! Any glassware broken after delivery voids all warranties. Thank you for understanding!
