Cork & Rubber Tapered Stoppers
Cork Stoppers & Rubber Bungs
Tall Tapered Stopper

An Airtight Seal
Solid, tapered natural cork stoppers and rubber bungs for test tubes, Erlenmeyer flasks, Florence flasks, plugging pipes, leaks & more.
All Indigo corks are made in Portugal to the highest standards for materials & cleanliness. Don't be tempted by short, cheap aggregates made from scraps that eventually fall apart after machine washing. Natural cork is fully autoclaveable & the material of choice for culturing needs in labs & home brewing.

- Tapered cork stoppers ensure airtight seals for cigars, spices and keep liquid culture media sterile after autoclaving.
- Rubber stoppers can be used with non-food items but should be washed in hot soapy water before use with food.
- A secure fit with our stoppers is only guaranteed with our glassware due to different specifications & tolerances.
**Check the size specifications table under Technical to make sure our stoppers will work with your glassware or other applications.
