Ideal for suctioning humid gases.

Ideal for humid gases and moisture-rich processes. The self-driving valve (patented) maintains vacuum levels and quickly exhausts moisture and solvents from the pump head, keeping it consistently dry.

Europe Explosion Protection Plan (ATEX) compliant

Compatible with all corrosive gases such as acidic gases and organic solvents. Adopts a structure diaphragm (patented) to achieve long service life. The TFM TM PTFE pump head and PTFE-coated diaphragm enable the transfer of explosive/flammable gases. Complies with European explosion-proof standards (ATEX), ATEX II 2G IIB+H2 T3X.

This is a high vacuum pump that achieves 100% oil-free operation.

Features (N920) Equipped with speed control function (flow control) Achieves ultimate vacuum of 0.2 kPa / 2 mbar Universal motor AC 90-230V, 50/60Hz (DC brushless motor) Gas ballast standard equipment Features (N950) High exhaust speed: 55 l/min Flow control possible with speed control Achieves ultimate vacuum > 0.2 kPa / 2 mbar Universal motor AC 100-240V, 50/60Hz Gas ballast standard equipment

It is particularly optimal for rotary evaporators with a vacuum controller.

Pressure adjustment in 1 mbar units Solvent recovery possible with a cold trap No solvent library required Automatic operation function prevents bumping and accommodates mixed solvents Compatible with high-boiling point solvents

This is a compact and affordable oil-free diaphragm vacuum pump. It is equipped with a function that allows manual adjustment of the exhaust speed as desired.

Design: The streamlined body based on ergonomics allows for easy surface cleaning. Space-saving: The extremely compact body saves valuable space in the lab. Chemical resistance: Compatible with many corrosive gases such as acids, alkalis, and organic solvents. Exhaust speed adjustment function: The exhaust speed can be easily adjusted using the adjustment knob. 1.5–7L/min (at atmospheric pressure). Hose connector: In addition to the included hose connector, other types can be installed as desired. (NPT 1/8 inch) Lightweight design: Weighing only 1.3 kg, it is easy to carry.
