High Accuracy Alternative to Mechanical Syringes For Laboratories

Laboratories can now use a higher accuracy alternative to mechanical syringes InterTech Development Company’s MicroPulse – a solid state means of producing small, short pulses of various gases.

The high accuracy compact (145x52x35mm) MicroPulse contains a miniature heat exchanger and precision temperature control that can be fitted into process control circuits without adding volume.

InterTech’s MicroPulse delivers gases up to 1.75scc/m at STP. The required flow during the pulse period is automatically controlled via an 8-bit digital interface by a PLC or other external controller.

The user can pre-set flow direction (inward or outward), volume-flow (cc/minute) or mass-flow (standard cc/minute) pulses over a wide pressure range. Overall accuracy and repeatability of 0.1% can be
achieved over extended periods of fully-automatic operation.

The multiple advantages of InterTech MicroPulse technology include: no moving parts or pneumatic valves to stick or wear; no small gaps or orifices to get clogged; no compressed-air source is required; application can initiate a flow pulse automatically, at any interval; and multiple different flow values can be produced in quick succession, as required by application.

Engineering analyses of testing application requirements and expected savings at specified gage R&R using InterTech patented test technology and customised software are available at no charge.
