Is this glassware compatible with other major brands like Corning or Chemglass?

Laboy glassware uses standard taper ground joints (e.g., 24/40) that are precision-ground. They are fully interchangeable with any other glassware adhering to US ASTM standards, ensuring a leak-tight seal with your existing setup.

Can this flask withstand high vacuum applications without imploding?

Yes. This is a heavy-wall design (hand-blown to approx. 3.5mm thickness) and has been thoroughly annealed to remove stress. It is specifically engineered to withstand the pressure differences of vacuum distillation safely.

I'm worried about breakage during shipping. How is it packaged?

We prioritize safe delivery. Each piece is wrapped in thick bubble wrap and cushioned within a sturdy, custom-fitted box.If it arrives damaged, we will replace it immediately.

What is the maximum temperature this glass can handle?

Made from premium Borosilicate 3.3 glass, it has a low coefficient of thermal expansion. It can withstand temperatures up to 500°C (932°F) for short periods and is highly resistant to thermal shock (sudden temperature changes).

What is the difference between "heavy wall" and standard glassware?

Standard glassware often has thin, uneven walls that are prone to cracking. Laboy glass is hand-blown by skilled lampworkers to ensure a uniform, heavier wall thickness (up to 2x thicker than standard), providing superior durability for lab use.
