The Hot Plate Which Has It All
The Wiggens WH220-R is an exceptionally versatile multi-functional hot plate / stirrer. It incorporates a round glass ceramic top plate and uses infrared technology for heat generation. The glass ceramic top plate has very good heat conductivity characteristics, which results in a safer and more efficient heat transfer from the heat source to the solution. In addition, it can resist up to 700°C of thermal shocks which comes in handy when the occasional spillover meets the fully heated top plate, a situation which often leads to cracks in conventional ceramic top plates. The infrared heater works way more efficient than traditional hot plates. It heats up quicker, can reach a higher maximum temperature, and create a much more stable temperature curve than its peers.
The round top plate fits perfectly to the wildly used 500ml and 1l beakers. Most importantly, it is shaped ideally for the addition of heating blocks. Wiggens offers a great number of heating blocks for flasks of all shapes and sizes. These heating blocks are all manufactured in-house so as to provide only units of the highest quality standards and to be able to provide custom-made solutions.
In addition, specifically selected stir bars make it possible to stir multiple flasks at once and by inserting a temperature sensor directly inside the heating block, utmost precise temperature measurement is possible. To top it off, the WH220-R employs a large LCD display with individual control and monitoring of the heating and stirring processes as well as a timer function.

Independent Scientific Reports Evaluate Air Versus Water Condensers
New scientific evaluations from the Department of Chemistry, University of Uppsala and the Australian National University report on their testing of the performance of the Asynt CondenSyn air condenser versus traditional water-driven condensers and an alternative commercial air condenser in ‘real-world’ laboratory conditions.
Synthesis labs are aware that water-driven condensers use a large amount of water which is wasteful / expensive and offer the possibility of leaks from the condenser which can result in flooding thus are keen to find an alternative.
In the two independent reports the Asynt CondenSyn air condenser displayed comparable performance to even the most efficient water-driven condensers and outperformed the alternative air condenser designs tested. For low-boiling solvents such as dichloromethane the Asynt CondenSyn was seen to provide superior performance to the water-driven condensers.
Given the advantages of the CondenSyn such as eliminating water consumption, less cluttered
working environments and ease of setting up and cleaning up reactions, both reports conclude that the CondenSyn is a superior choice to water-driven condensers. In addition by combining the CondenSyn with a heating block system, reflux set-ups can be prepared quickly and easily with no chance of water or oil spillages.

Recirculating Chillers Improve Bioreactor Yield and Reduce Operating Cost
PolyScience offers almost two dozen recirculating chillers designed to maintain bioreactors at the constant temperature required for optimal bacterial and yeast growth. A highly reliable and cost-effective alternative to expensive, inconsistent and wasteful tap water cooling, PolyScience Benchtop Chillers and 6000 Series Chillers help ensure maximum yield in the bioproduction of pharmaceuticals, antibodies and vaccines.
PolyScience Benchtop Chillers offer a compact and easy-to-operate solution for cooling bioreactors up to 10 litres in size, maintaining temperature with ±0.1°C stability and delivering cooling capacities as high as 1610 watts. Seven different models are available; all feature a space-saving design, large easy-to-read LED display and a choice of pumps.
For bioreactors larger than 10 litres, PolyScience 6000 Series Chillers are recommended. They also maintain temperature with ±0.1°C stability and feature large, dual displays that present temperature and pressure or flow rate simultaneously. These chillers are available with cooling capacities as high as 2900 watts, compressor sizes from ¼ to 1 HP, and positive displacement, centrifugal, or turbine pumps.
All chillers feature readily accessible, reusable fluid and air filters, which are easily removed for cleaning, helping simplify maintenance and ensuring energy efficiency. Find the right chiller for your application with the interactive product finder. Or for more information, visit
