FAQs

What is the PTFE compound rotary evaporator seal?

The PTFE compound rotary evaporator seal is a vacuum-sealing accessory for rotary evaporators. It provides a high‑tightness, durable vacuum seal that helps maintain vacuum integrity during evaporation and solvent recovery processes.

Why is PTFE used for this vacuum seal?

PTFE is a fluoropolymer with exceptional chemical resistance and low friction, making it ideal for harsh lab environments where aggressive solvents and chemicals are present. Its thermal stability and inertness help prolong seal life and reduce degradation compared to standard elastomers

What role does the FKM sealing ring play?

The FKM elastomer sealing ring enhances sealing performance by providing flexibility and compression that ensures tight contact between surfaces. Combined with PTFE’s chemical resistance, this design yields a robust, long‑lasting vacuum seal suitable for demanding rotary evaporator use.

Where is this seal used?

This seal is used in rotary evaporator systems to prevent leaks and maintain a stable vacuum during solvent evaporation, concentration, and distillation tasks in chemical labs. Reliable vacuum integrity is essential for efficient solvent recovery and temperature control.

How long does the seal typically last?

Service life depends on operating conditions (temperature, chemicals, vacuum level), but the combination of chemical‑resistant PTFE and flexible FKM generally delivers longer service life and fewer replacements than seals made solely from elastomer materials.
