Cork Stands From USA Lab
Stable, Heat-Resistant Support for Round-Bottom Flasks
Cork stands are one of those simple but essential tools that keep your lab work steady and safe. USA Lab cork stands provide reliable support for round-bottom flasks during heating, cooling, or storage. Made from thick, high-density cork, they provide insulation from hot surfaces and prevent glassware from rolling or tipping.
Designed for Everyday Lab Work
Heat-Resistant Cork Material
Protects flasks and benches from residual heat after heating or reflux, providing a natural layer of insulation that minimizes thermal shock and surface damage.
Secure, Non-Slip Design
Prevents round glassware from rolling or tipping during setup or cooldown by keeping vessels stable and reducing the risk of breakage or spills.
Multiple Flask Sizes
Fits from 250mL to 2L round-bottom flasks, offering flexible support for a wide range of distillation and reaction vessels.
Lightweight and Durable
Easy to move, store, and reuse without cracking or shedding, maintaining its shape and grip through repeated heating and cooling cycles.
