AAdvance Instruments Lab Cork Stand Ring - 140mm X 90mm - For 500-2000mL Flasks - Pack Of 3

This is a pack of three cork stand rings from AAdvance Instruments.

Each ring measures 140mm by 90mm and is designed to support flasks from 500mL up to 2000mL in the lab.

The cork material provides a soft, stable base that won't scratch glassware.

Perfect for chemistry labs, schools, or home setups.

They're brand new, unbranded in terms of MPN, but solidly made.

If you need to keep your round-bottom or flat-bottom flasks steady on the bench, these cork rings do the trick.

Three in a pack, so you've got spares or can support multiple setups.

Simple, functional, lab-ready.
