Filter Characterization
Characterize a filter’s flow versus pressure drop curve by fixing the differential pressure across the filter using the pressure controller. The mass flow meter displays the resulting flow rate required to attain the pressure drop.
Faster Leak Testing
Establish stable pressure for the leak check by measuring pressure precisely at the device under test with Alicat’s PC3-series pressure controller with remote sense port. This method negates the pressure drop induced by the mass flow meter that is measuring the leak rate with 5-ms speed of response.

Monitoring and Recording Bioreactor Output
Applications like methane production or hydrogenation benefit from comparing the mass of gas added to the bioreactor with the mass that has been outgassed. When outgassing occurs at atmospheric pressures, the very low pressure drop of Alicat’s Whisper series will not induce backpressure while quantifying outgassed mass.

Optimizing Bioreactor Production
Bioreactors are used in a growing number of applications, from producing bio-adaptive medicines or environmentally friendly fertilizers and pesticides, to brewing beer, refining ethanol and treating wastewater. The increase in biologics production and single use reactors has led to a need for even greater precision and flexibility in instrumentation.
High Flow Control for Gasification
Alicat Scientific mass flow controllers can be used in multiple areas of the gasification process: combustion, clean-up reactors, safety, & quality control. Get more precise syngas production, redundancy between units and extremely fast control. Alicat’s MCR controllers use near-frictionless Rolamite proportional control valves to rapidly and precisely control flow rates up to 5000 slpm. With accuracy of +/- (0.8% of reading + 0.2% of full scale range) to high flow rates, precise composition can be ensured.
Lowered Cost and Increased Speed for Biologics Production
With protocols for bioprocessing now firmly established, there is an increasing focus on reducing the cost of producing biologics, biosimilars, mABs and other modern medicines that require bioreactions and current trends toward single use bioreactors. You can reduce your cost per run and extend your processes with Alicat’s mass flow accuracy as low as 0.1% of full scale and unbeatable repeatability of +/- 0.02% of full scale readings.
Aerobic vs. Anaerobic Wastewater Treatment: An Overview
Bioreactors are now a common part of wastewater treatment. Alicat’s revolutionary differential-pressure based mass flow controllers allow for extreme flexibility in mass flow control and the response times needed to make this process efficient and cost effective.

- STP/NTP: user-selectable (defaults to 25°C & 1 atm STP/0°C & 1 atm NTP)
In the box
- High-pressure portable mass flow meter (fully charged)
- Micro-USB charging cable and AC wall adapter
- NIST-traceable calibration cesrtificate
- Alicat operating manual
Model Variations
- Aggressive gases (MBQS, see below)
Also available:
- Standard configuration, up to 160 psia (MB)
- Low pressure drop, max 60 psia (MWB)
Corrosive Gases (MBQS series)
Instruments in the high-pressure MBQ series are also available with an optional “S” configuration (MBQS) for use with corrosive gases. In this configuration, we upgrade the flow body and sensor to 316L stainless steel and the elastomers to FFKM.
Build Options
- Communications protocols (RS-232, RS-485)
- Displays (monochrome or color)
- Process connections (NPT, SAE, AN, BSPP/G, welded compression or VCR/VCO fittings)
- Elastomers (Viton, FFKM, EPDM, Silicone)
Alicat’s MBQ series is suitable for use with non-corrosive gases.
