Nanotech research syringe replaces mechanical syringes

(September 16, 2010) — InterTech Development Company’s MicroPulse is a solid state means of producing small, short pulses of various gases for research in nanotechnology fields. The high-accuracy, compact (145 x 52 x 35mm) 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.  

With MicroPulse, there are no moving parts or pneumatic valves to stick or wear. There are no small gaps or orifices to get clogged. No compressed-air source is required. Application can initiate a flow pulse automatically, at any interval. 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 customized software are available gratis from the company.
