  • Cold Traps and Woulff Bottles: Add an extra layer of protection against volatile vapors using KGW Isotherm Dewar traps.
  • Waste Bins: Safely dispose of recovered solvents and used consumables in B. Braun Medibox containers.
  • Chemical Sorbents: Ensure workstation safety during solvent flask handling with Brady Spill Kits.

 

Unsure if your distillation requires the 1.7 m3/h flow rate of the PC 3001 VARIO pro or the remote capabilities of the KNF SC 920 G? Our team provides local technical support to help you find the correct speed-controlled solution with fast shipping and competitive pricing.

 

Frequently Asked Questions

 

1. What are the benefits of VARIO® speed control?

VARIO® technology automatically adjusts the pump's motor speed to maintain the exact vacuum level required, resulting in shorter process times, reduced maintenance, and significantly quieter operation compared to fixed-speed pumps.

2. Can these units handle corrosive chemical vapors?

Yes, units like the Vacuubrand PC series and KNF chemistry systems are constructed with chemically resistant materials like PTFE and FFKM to ensure longevity when pumping aggressive laboratory gases.

3. Do speed-controlled pumps help prevent sample loss?

Absolutely. By precisely controlling the vacuum and responding to pressure changes in real-time, these units prevent "bumping" or sudden boiling, which protects your valuable samples during evaporation.

4. Are these systems compatible with my existing rotary evaporator?

Most speed-controlled units are designed for universal connection, though specific models like the Heidolph ROTAVAC Vario are optimized for digital integration with same-brand evaporators.
