BASIS™ MEMS Thermal Mass Flow Meters & Controllers
Small flow mass flow instruments with the performance of a premier product.
Alicat Scientific’s smallest mass flow controller uses MEMS thermal technology to measure mass flow. Cost-effective, small enough to fit in the palm of your hand and yet packed with impressive performance. Work with our engineering team for custom manifolds and gas mixing arrays.
- Accurate flow control in a compact, durable, metal flow body.
- Run sophisticated flow-control scripts using a fast, robust Alicat ASCII command set.
- Dispense dosing and batches with a built-in totalizer.
Compact manifolds
Ideal for benchtop bioreactors, glass manufacturing, and OEM builds with space constraints. Contact us with your specifications.

BASIS improves industry efficiency
Verify flow and optimize carrier gas control in gas chromatography
Enable full system stability. Fluctuations in flow rate disrupt the detection of chemical compounds. Tightly regulate carrier gas flow rate to ensure accurate compound detection, using a BASIS electronic mass flow controller.
Lowering cost and increasing speed of biologics production
Ensure your process is repeatable and scalable. BASIS provide accurate and responsive gas flow with a large turndown ratio and integrated gas selection. The number of spares required is reduced without sacrificing performance.
Ensure consistent batches in glass production
BASIS mass flow devices are used in burner control applications to control gases that heat the glass and facilitate drawing. Scripting and electronic control make your process repeatable and precise. Great for production of lab-quality and other high-volume, low-variability glass.
Gas mixing in molar ratios
Use BASIS mass flow controller’s intuitive serial commands to make gas mixtures in molecular proportions, and stop paying premiums for custom mixes.
