500mL Single‑Neck Round‑Bottom Boiling Flask With 24/40 Ground Joint, Heat‑Resistant Borosilicate Glass Laboratory Glassware
- Stock: In Stock
- Model: MZ003820
- SKU: MZ003820
Product Features
This 500 mL single‑neck round‑bottom boiling flask is constructed from premium borosilicate glass material. It adopts standard 24/40 ground outer joint for connecting other lab glass components. Borosilicate glass features low thermal expansion coefficient, delivers good thermal‑shock resistance and excellent chemical corrosion resistance. Round‑bottom design supports uniform heat distribution, ideal for liquid heating, boiling, distillation experiment and rotary evaporator application in chemistry laboratory. Important Safety Reminder: Laboratory glassware, risk of cracking and breakage. Wear protective eye‑goggles while conducting experiments. Package includes round‑bottom flask main‑unit only. Clamps, heating mantle, condenser and other lab accessories shown in demo‑pictures are not included.
