Microfluidic Back Pressure Controllers

Bronkhorst® model IQP-700C Back Pressure Controllers are miniature devices which are ideal for use in cramped environments or in systems requiring minimum internal volume e.g. desktop equipment. The Pressure Controller has a chip-based (MEMS) sensor and is suited for pressure ranges between 0,1…0,5 bar and 2…10 bar absolute or gauge. Communication with the devices can be either in analog mode or digital over RS232 or RS485.

The ultra compact IQ+FLOW instruments are typically recommended for integration in analytical, bioprocessing and medical equipment.
