New Pressure Sensor Technology Provides Ten Times Greater Accuracy and Stability
SamplePrep & Pesticide Reference Materials
2010 Geno/Grinder The ultimate plant tissue homogenizer, proven to increase throughput and extraction effi ciency for pesticide residue analysis.
SPEX CertiPrep off ers ISO 17025 and ISO Guide 34 accredited pesticide reference materials for GC, GC-MS and HPLC.
The new TERPS (Trench Etched Resonant Pressure Sensor) technology platform from GE Sensing & Inspection Technologies (UK) allows accuracy and stability greater by a factor of ten over existing piezoresistive pressure sensors, while significantly extending the pressure range capability conventionally associated with resonating pressure technology (RPT) sensors. TERPS technology is the result of extensive research and development into the design and manufacture of silicon resonating pressure sensors with a wide range of applications, from aerospace to sub-sea and from process engineering to industrial instrumentation.
As Steve Sajben, product manager for pressure sensors, explains, “Through our Druck heritage, we have been able to offer a resonant silicon product in the RPT Series for some years. Over this time we have continued to develop our sensor expertise, both within GE and in collaboration with Universities. The technology and manufacturing process developments we have explored and created now allow us to produce a pressure sensor with all the inherent accuracy and stability of resonant silicon, but with significantly greater capability in terms of pressure range, temperature range, and mechanical packaging.”

New Mixer Improves Comfort and Convenience in the Laboratory
Velp Scientifica (Italy) introduces the Vortex WX with orbital movement that doesn’t need any pressure to maintain vibration. Thanks to the revolutionary “Sensor” mode, an infrared system (IR) detects the presence of the test-tube and the instrument automatically starts vibrating.
The Vortex WX has adjustable vibration frequency and can reach up to 3000 rpm, according to need. The Vortex WX features a low profile and ergonomic design for increased lab bench stability.

New Miniature IR Temperature Sensors
The MI3 from Raytek (Germany) is a rugged, IP65 stainless steel miniature pyrometer with integrated electronics measuring in the temperature range from minus 40 to 1650°C. Just 14 mm in diameter and 28 mm long, the single piece OEM version is the smallest fully functional, stand alone infrared temperature sensor for fixed installation on the market today. Compared to most IR temperature sensors on the market, where the measurements are transferred from the head to the electronics as analog µV signals, the new MI3 sensors allow calibrated, digital temperature output directly from each sensor head.
Infrared thermometers, such as the MI3, are the fastest, safest and most cost- effective way to measure critical temperatures necessary for process control and automation. The broad temperature range and expanded feature set allow the Raytek MI3 to satisfy the requirements of nearly any industrial application and enables seamless installation into existing control equipment or OEM systems.
