Welch™ Welch™ ChemStar™ Dry Deep Vacuum System
Oil-free deep vacuum performance
Supplier: Welch™ 2070B01
Description
ChemStar Dry deep vacuum system handles harsh chemical applications with ease – and no oil mess. Achieve deep vacuum to 50 millitorr, with high flow of 150L/min at 2 torr– perfect for many demanding evaporative processes.
Features
- Wetted surfaces chemically resistant
- Oil-free dry vacuum technology
- Pumps high vapor loads of solvents or corrosive wet chemistries
- Cold-trapping not required for select applications
- Programmed blower/diaphragm pumping system optimization (patent pending)
- Self-cleaning forcontamination-free surfaces
- Quiet, low vibration system free of oil fumes
Advantages
- Pumps vapors that would compromise oil-seal pumps - solvents, acids, etc.
- No oil maintenance/disposal, no sample contamination from oil or particulates
- Achieves top pumping speed at the optimal working vacuum level for most evaporations
- Ends dry ice trapping expense and effort for many processes
- Coordinated blower system electronically adjusts to vapor load for fast, deep vacuum and efficient evaporative performance
- Self-cleaningmaintains consistent performance and extends maintenance intervals
- Fits into lab environment
- Schlenk line drying manifolds, no cold trap required
- Freeze drying – to 6.5L, no cold trap required
- Vacuum ovens – to 5 ft.3, cold trap required for select applications
- Concentrators – multiple units in parallel, cold trap required for select applications
