PRINCETON, N.J., June 29, 2012 /PRNewswire-iReach/ -- There is an increasing trend in the biopharmaceutical manufacturing industry toward the use of disposables (e.g., flexible tubing and disposable bioprocess containers) in both clinical and commercial production.   The polymer components found in PendoTECH's single-use sensor offer a stainless steel replacement that can drastically shrink carbon footprints.  According to BioPharm International's The Environmental Impact of Disposable Technologies, disposability frees the user from the constant sterilization between batches and releases them from the high use of water and chemicals that can dramatically decrease water consumption by 87%.

While cumbersome pressure gauges and stainless steel pressure transmitters have been traditionally used in bioprocessing for pressure monitoring which in turn facilitates either manual or automated process control by making process adjustments based on the process pressure data.; consuming and heating large volumes of water to clean and sterilize stainless-steel equipment is more energy demanding than producing single use sensors.  The pressure sensing chip installed in the PendoTECH plastic flow-through devices is manufactured using a silicone micromachined piezoresistive element in a Wheatstone bridge circuit.  Having a sensor embedded into the wall of the fitting enables PendoTECH's Single Use Pressure Sensors to have an unobstructed flow path. 

In addition to significantly reducing the risk of contamination, these plastic sensors can have a second life as an energy source after being used.  With a heat value that is actually higher than coal, the plastic used in PendoTECH's Single Use Pressure Sensor waste is ideal for cogeneration.  According to the U.S. Clean Heat and Power Association, cogeneration systems decrease energy use by almost 1.3 trillion BTUs/year.  When single-use systems are incinerated, signif
