Applications

ANALYTICAL INSTRUMENT FOR AIRBORNE PARTICLES

CUSTOMER CHALLENGE

The manufacturer of a device to analyze air contaminants needed a fluid transfer system to dispense samples in a liquid carrier onto an identification card. Their combination of tubing, valves and pumps from different suppliers was too large for the instrument and too imprecise to control the sub-micro liter fluid volumes required.

IMI SOLUTION

IMI engineers designed an integrated system that comprised Kloehn syringes, syringe pumps, rotary valves and drivers, solenoid valves and all the tubing and acrylic assembly required. The sub-assembly was engineered to meet specific customer requirements – no costly extras – and to integrate easily into the customer’s instrument.

PORTABLE VENTILATOR & RESPIRATORY THERAPY DEVICE

CUSTOMER CHALLENGE

A customer was designing a respiratory therapy device and required an pneumatic handling solution in a very small footprint that needed to be portable and therefore lightweight with limited power consumption.

IMI SOLUTION

The IMI assembly integrated an accumulator, valves, pressure transducers, a custom block and built-in filter assembly. This manifold assembly was created to fit into a compact housing. Integrating the accumulator and filter allowed the assembly to fit the small footprint and reduced weight thereby enabling portability. Valves were designed and manufactured by IMI’s FAS division for manifold mounting and combined with and IMI KIP manifold solution delivering a single-source turnkey assembly, simplifying customer sourcing.


DNA ANALYSIS SYSTEM

CUSTOMER CHALLENGE

In this lab on a chip application, the OEM needed to move small biological samples and multiple reagents at high speeds with high reliability.

IMI SOLUTION

IMI recommended, designed and manufactured an acrylic manifold because of the complexity of air channels routed to multiple locations. An acrylic laminated manifold allowed IMI to deliver a complicated but compact structure at a reasonable cost. The four-layer laser-bonded manifold holds nearly 60 valves, each meeting different requirements for speed, longevity and salt and moisture resistance depending on their function. The manifold had to be designed to mate with a chip, so dimensional stability was critical.
