Chemvak C900 Series

The Chemvak C900 series by Wiggens offers a high-performance solution for labs handling aggressive vapors and corrosive gases. These oil-free pumps are available in South Africa through Apex Scientific, combining PTFE chemical resistance with advanced vacuum control. Designed for longevity and minimal maintenance, the series supports efficient, safe operation across a wide range of laboratory processes.

 

Built for Corrosive Lab Conditions

Each Chemvak C900 series pump uses PTFE or PTFE-coated materials in all wetted parts. This design ensures excellent resistance to acidic, basic, and solvent vapors. The gas and drive chambers are separated, which helps prevent contamination and increases the system’s life span.

 

Compact, Quiet, and Efficient

Despite their compact footprint, these pumps deliver strong vacuum performance. They achieve fast pumping speeds and deep ultimate vacuum, making them ideal for rotary evaporation, distillation, filtration, drying, and other laboratory applications. Quiet operation and low vibration levels also support use in sensitive environments.

 

Smart Safety and Vacuum Control

Every model features built-in overheat protection. If temperatures rise too high, the pump shuts down automatically and restarts once safe. Select models include frequency conversion for precise vacuum control, helping stabilize pressure and reduce fluctuation—critical for long-duration tasks.

 

Reliable Performance Across Models

Models in the Chemvak C900 Series—including options like the C900E, C920Z, C960T, and C980V—offer flexible configurations to suit different needs. Whether you’re managing large-volume distillations or sensitive extractions, there’s a model that fits your workflow.

 

Trusted Equipment for South African Laboratories

The Chemvak C900 Series supports sustainable, oil-free vacuum systems that lower operating costs. As part of Apex Scientific’s reliable laboratory equipment range, these pumps meet the needs of professionals across chemical, pharmaceutical, petrochemical, and semiconductor industries in South Africa.
