## Questions & Answers

**Q: Is this glassware compatible with other major brands like Corning or Chemglass?**
A: 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.

**Q: Can this flask withstand high vacuum applications without imploding?**
A: 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.

**Q: I'm worried about breakage during shipping. How is it packaged?**
A: 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.

**Q: What is the maximum temperature this glass can handle?**
A: 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).

**Q: What is the difference between "heavy wall" and standard glassware?**
A: 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.
