Product Description The rotary evaporator condenser tube designed specifically for high-end laboratories is made of high borosilicate glass (Borosilicate Glass 3.3), which has excellent thermal stability and chemical resistance, can withstand extreme temperature differences from -20 ° C to+500 ° C, and will not deform or crystallize after long-term use. The innovative multi-layer spiral structure significantly improves the gas-liquid contact area, coupled with precise channel design, achieving rapid heat exchange and increasing condensation efficiency by more than 40%. Built in triple sealing system - O-ring+conical grinding mouth+vacuum sealing gasket, ensuring no leakage and zero volatilization. Suitable for continuous distillation and recovery of organic solvents and high boiling point substances, it is an ideal configuration for pharmaceutical, chemical, and scientific research institutions.
