Keep Your Round Bottom Flasks Safe & Upright – 2 Pack Cork Flask Support Stand If you work with round bottom flasks in a lab, classroom, or home brewing setup, you know how easily they roll away, tip over, or get damaged on hard surfaces. This 2‑pack of cork flask supports provides a simple, reliable, and chemical‑resistant solution to hold flasks securely in place. Why Choose This Cork Flask Stand? Perfect Fit for 250–2000 mL Flasks Each stand has a top diameter of 110 mm (approx. 4.3 inches) and a concave design that naturally cradles round bottom flasks. Whether you're using a small 250 mL flask or a large 2000 mL flask, the cork surface conforms gently to the glass for stable, wobble‑free positioning. Natural Cork – Lab‑Friendly Material Cork is naturally elastic, non‑toxic, and odorless. It offers excellent heat insulation (safe for hot flasks straight off a burner) and electrical insulation. Unlike foam, cork won't melt or degrade with moderate heat. It is also flame‑resistant, adding an extra layer of safety in the lab. Chemical Resistance You Can Rely On Our cork stands resist acids, alkalis, and many common laboratory reagents. They won't swell, crack, or corrode when exposed to spills or fumes – making them far more durable than cardboard or untreated wood alternatives. Protect Your Glassware Investment Round bottom flasks are expensive and fragile. Placing them directly on a metal grate or hard bench invites scratches, chips, or catastrophic rolling. The soft yet firm cork surface cushions your flask, while the high friction coefficient keeps it from sliding. Your glassware stays clean and intact. Ready for Any Lab Environment Use these stands on laboratory benches, in chemistry classrooms, at hospital workstations, in chemical plants, or in your home hobby lab. They are also perfect for holding spherical decorative bottles, terrariums, or even as a non‑slip pad for other round containers.
