VACUUBRAND MD 4C NT +2AK Chemistry Vacuum System is a high-performance diaphragm vacuum system engineered for demanding chemical, biological, and pharmaceutical laboratory applications. With outstanding chemical resistance and superior vapor tolerance, this vacuum system delivers exceptional results across a broad range of applications including rotary evaporation, vacuum concentration, and drying processes.
Key Features:
- Ultimate vacuum of 1.5 mbar (1.1 Torr) and pumping speed up to 2.2 CFM (60 Hz)
- Excellent vacuum stability, even when operating with gas ballast
- Advanced four-head, three-stage diaphragm design ensures robust performance at low vacuum levels
- Outstanding chemical resistance and superior vapor handling capability thanks to all wetted parts designed for aggressive chemicals
- Integrated inlet separator (AK) made of coated glass retains particles and droplets, enhancing pump longevity
- Outlet catchpot prevents condensate backflow and contributes to exceptionally quiet (45 dBA) operation
- Low vibration and low maintenance with oil-free diaphragm technology
- Compact footprint saves valuable lab bench space
Typical Applications
This chemistry vacuum system is ideally suited for evacuation, evaporation, and gas or vapor handling in labs that do not require solvent condensation at the outlet. Well-proven for high vacuum needs involving high boiling solvents, it excels with rotary evaporators, vacuum concentrators, and drying ovens.
Included with the System
- Power cord
- Fully assembled pumping unit ready for use
- Operator’s manual
- Manufacturer’s documentation
- 2-year manufacturer’s warranty
