Rotavac Valve Tec Two-Head Diaphragm Vacuum Pump

Two-head diaphragm pump for laboratory vacuum applications. Solvent-wetted parts are constructed from chemically resistant materials, making this pump suitable for sustained use with organic vapours and corrosive reagents.

Key Specifications

• Pump heads: Two diaphragm heads
• Chemical resistance: All solvent-wetted parts manufactured from chemically resistant materials
• Technology: Oil-free — clean vacuum, no cross-contamination
• Model: Rotavac Valve Tec

Typical Applications

Designed to couple directly to rotary evaporators, but equally suited to vacuum filtration, reduced-pressure distillation, and any process requiring stable, oil-free vacuum.

Commonly used in organic chemistry, synthesis, quality control, and pharmaceutical laboratories.

Dual-Head Advantage

The two-head configuration provides higher volumetric flow and achieves deeper ultimate vacuum than single-head units — relevant when working with high-boiling solvents or carrying out distillations at very low pressures.

Maintenance

Oil-free design eliminates fluid changes and vacuum system contamination. Diaphragms are user-replaceable — no special tooling required.
