Mass Flow Controller
High-performance mass flow controllers and meters are available from Sensirion, Stafa, Switzerland. The SFC5500 mass flow controllers are calibrated for multiple gases and come with push-in fittings, which can be easily swapped out from a list of compatible parts. They are available in ranges from 50 sccm to 200 slm. The SFM5500 is a valveless version. The pressure-resistant mass flow meters are available in four flow ranges: 50 sccm, 0.5 slm, 2 slm, and 10 slm. The sensor is based on the micro-thermal measurement principle and uses the company’s CMOSens® MEMS technology. The mass flow controllers/meters are suitable for applications such as gas mixing in medical instruments.

Smart Pipette
Festo, Islandia, NY, has developed a closed-loop smart-pipette for automated, high-speed dispensing systems. The new DHOP smart pipette with DHAP low-force-tip family is designed for automated pipette applications where precision, validation, and process monitoring are needed. The DHOP’s three pressure sensors validate the performance of every dispense. Sensor data can be used to track dispense volumes and fluid characteristics. The pipettes can alert to clogged tips and sense liquid levels. The DHOP closed-loop technology and the DHOE open-loop pipette is based on pressure over liquid technology. It allows the operator to program in engineering units (μl, ml), and the pipette accurately and repeatably dispenses that volume utilizing multiple pressure and temperature sensors and sophisticated software feedback.

Media Isolation Valve
A solenoid-operated device from Clippard, Cincinnati, OH, uses a flexible diaphragm to isolate the actuation mechanism from the fluid path. All wetted areas of the NIV Series media isolation valve are either PEEK or PTFE, making this series ideal for use with corrosive media. A unique feature of the series is the one-piece valve stem that functions as a sealing membrane while also supporting and centralizing the poppet in the seating area. This multifunctional poppet/ diaphragm/stem results in a simplified design with fewer parts (only two for the 2-way and three for the 3-way), longer life, and zero dead volume. Four orifice sizes are available as 2-way normally closed, 2-way normally open, or 3-way selector/diverter.
