69 Sample Preparation & Processing Safeguarding Samples from Potential Thermal Degradation
Genevac has announced the latest version of its proprietary autostop when dry control software which allows it’s EZ-2, Rocket and HT-Series evaporators to automatically detect when the samples are dry and then shut it down, safeguarding valuable samples from potential thermal degradation.
Combined with Genevac’s continuous running condensers, autostop when dry control software allows easy unattended operation offering the possibility of significant increases in productivity through use of overnight evaporation runs.
Until the introduction of autostop when dry control software - evaporators users had to constantly monitor or estimate the drying time for a given sample. Genevac autostop when dry control software overcomes this problem by using one of two methods to determine when dryness has been reached and then automatically shutting down the evaporator without further user intervention.
With Genevac evaporators the software detection of sample dryness is determined either by the rate of heat flow into the sample or by temperature convergence using pre-positioned probes in sample holder and sample. Either method gives significant time savings over traditional manual methods as well as freeing up operator time for other more productive tasks.

Next Generation Hotplate and Stirrer Announced
Wiggens’ innovative technology has been used to produce the new generation round top hotplate-stirrer WH240 series. The hot plate uses unique infrared technology with a power of up to 600W and the ceramic glass has a high infrared transparency which results in a very high heating efficiency in a standard round top plate of 135mm diameter. Optimised PID parameters allows many different kinds of applications.
A specially designed stainless steel protection ring, sealed outer shell of the top plate, and the robust ceramic glass can resist a thermal shock of 700? guaranteeing an enhanced longevity of the instrument. The control system has been updated to a higher level using a bright LCD display with adjustable backlight for user friendly monitoring and setup.
Adjustable safety temperature setting using independent safety temperature circuit ensures a high safety level. A well-chosen design with reliable embedded temperature sensors inside the ceramic glass top plate makes the control more stable and accurate. A wide range of accessories suitable for the standard top size can provide uniform heating for multiple size vials in parallel reactions with a superior stirring effect as well. The products are now available for the international market with various voltage standards.
