The STEM Integrity 10 Reaction Station from electrothermal enables you to conduct 10 different reactions simultaneously within the same unit, each reaction being conducted within its own cell, at its own individual temperature and stir rate.
If desired, fast heating and cooling rates can be selected, with temperature ramps of between 0.1°C/min to 5°C/min. There is also a crash function for even faster temperature changes, which is ideal for kinetic determinations. Extreme temperature accuracy is guaranteed, with a temperature stability of ± 0.5°C and a minimal set point overshoot of 0.5°C. The temperature may be maintained either through the block itself or by using a probe within each cell’s solution.
This accuracy can be maintained over a wide temperature range of -30°C to 150°C, with precise, independently controlled temperature profiles, and homogeneous sample mixing may be assured with stirring rates of between 350rpm to 1200rpm using magnetic stirrers. With working volumes of between 2ml to 25ml, the STEM Integrity 10 is an excellent screening tool for most laboratories and can also be used to establish ideal process conditions.
The STEM Integrity 10 Reaction Station is a very time efficient way of conducting chemical experiments, speeding up investigative chemistry by up to 10-fold. Chemical reactions, involving either synthetic chemicals or naturally occurring substances, are universally impacted by heat and the STEM Integrity 10 lets you assess the impact of both temperature and stirring rate upon reactions. The beauty of the STEM Integrity 10 is that it combines flexibility with accuracy: It allows you to run 10 experimental variants simultaneously within the same unit, whose temperature and stir rate you can precisely
and individually control. You can design temperature profiles for each individual experiment and record everything electronically; all results are captured and stored automatically, so you can be working (or relaxing) elsewhere whilst the STEM Integrity 10 has everything under control.
You can add further refinements to increase the usefulness of this apparatus, for example, by adding reflux condensers to maintain sample volumes. As an accessory ,PTFE gas inlet/outlet heads permit working under vacuum conditions or inert gas conditions with a nitrogen or argon blanket. The possibilities for attachments are endless, and to illustrate this, we have developed a Clarity System which utilises the STEM Integrity 10 to conduct solubility and rystallisation studies.
Whilst there is obvious potential for screening reactions in investigative chemistry or drug discovery laboratories, let’s not forget about process monitoring laboratories. The STEM Integrity 10 can be very useful for establishing the ideal reaction conditions of many industrial chemical processes and can more than earn its keep as a great trouble-shooter, pinpointing the cause of process malfunctions due to temperature. It saves time, bench space and electricity, is easy to clean, and since the working volume of each reaction cell is between 2 and 25ml, it is very economical on reagents as well.
