Genevac (UK) has announces the Puck - a new accessory that extends the sampling versatility of its Rocket™ Evaporator to simultaneously accommodate up to eighteen 60ml Accelerated Solvent Extractor (ASE®
) tubes.
For environmental, food and agricultural scientists that commonly employ solvent extraction techniques - concentration of extracted samples prior to analysis has traditionally been a time consuming manual process involving exposure to organic solvents.
Many RH instruments installed in high-humidity applications suffer from poor reliability because the electronics are exposed to the harsh, damp environment.
The miniature PCmini52 probe from Michell Instruments (UK) overcomes this problem with electronics that are encapsulated in a protective resin and so are completely protected from the atmosphere. This gives the instrument an IP65 rating and enables the probe to provide reliable measurements no matter how high the surrounding humidity.
The PCmini52 humidity transmitter uses a capacitive thin-film polymer sensor which either absorbs or releases water vapor as the relative humidity of the ambient air rises or drops. These sensors, developed by Michell’s Coreci division, offer both a fast response and excellent sensitivity to fluctuations in humidity.
The PCmini52 is a flexible option, offering different output voltages. In addition to its miniature size, it can be configured with both plastic and stainless steel housing for additional protection. A low power consumption of 3mA (output 0-1 Volt) makes the PCmini52 flexible enough for battery operated or wireless applications as well as fixed installations.

Benefiting from a new patented low temperature, low pressure steam heating technology developed by Genevac – the ASE Compatible Rocket Evaporator is able to uniquely achieve the dual goals of very fast evaporation with very precise temperature control thereby accelerating the safe concentration of extraction samples. Evaporation of ASE tubes is fast, safe and provides excellent recoveries of even the most volatile analytes. In addition Genevac’s patented Dri-Pure® prevents solvent bumping and cross contamination inherent with rotary evaporator and other vacuum evaporation systems.

Offering true unattended operation capability the Rocket Evaporator requires no training, even a beginner can competently use the system in less than 5 minutes. A 2-stage cold trap built into the Rocket Evaporator provides very high levels of solvent recovery, even with volatile organic solvents. Requiring no peripherals for operation the compact Rocket Evaporator fits neatly onto a laboratory bench or into a fume hood. All key components on the robust and reliable system are user serviceable ensuring a low the cost of ownership.
