Silicone Stopper, Conical Solid, 10 Pack

We use these stoppers for chemical bottles in our lab. They provide a secure fit and are resistant to most chemicals. They��re a good addition to our lab supplies.

Used these stoppers for sealing lab flasks, and they work well. They create a tight seal and are easy to remove when needed.

These solid silicon stoppers are incredibly reliable. The 10-pack is a great value, and they maintain their shape and pliability over time.

The quality of these stoppers is good for lab equipment. They fit snugly and are flexible enough to handle frequent use.

I use these silicon stoppers in my lab, and they work perfectly. They��re resilient and last a long time.
