PROGRAMMABLE GAS FLOW REGULATORS

Precise Gas Flow Control with an Intuitive Touchscreen Interface
Easily view, modify, and visualize gas flow profiles directly on the device — no external software required.

Smart Gas Flow Control

The LAMBDA MASSFLOW touch is a programmable digital gas flow controller designed for stand-alone use or seamless integration with the LAMBDA Minifor2Bio touch laboratory bioreactor. A laminar mass flow sensor ensures precise measurement with minimal pressure drop. The gas flow is regulated by LAMBDA's proprietary, microprocessor-controlled proportional needle valve.

Precise Gas Flow Regulation

The MASSFLOW touch ensures accurate gas flow measurement that remains largely independent of pressure and temperature variations.

O₂-Enrichment

Boost oxygen supply for high-density bacterial and yeast cultures. The MASSFLOW touch provides controlled O₂ addition exactly when and where it's needed.

Automatic Gas Mixing

Combine several MASSFLOW touch units to mix gases such as N₂, Air, O₂, and CO₂ with precision – ideal for creating defined gas compositions or adjusting specific concentrations.

Automatic pH Regulation

Keep culture pH within the optimal range effortlessly. The MASSFLOW touch precisely doses CO₂ in real time to control acidity.

MASSFLOW touch – Smart, precise gas regulation for every lab!
