33 Ovens, Furnaces & Heating Equipment Best Practice Guide for Safely Using Laboratory Heating Blocks
Asynt announce an updated 2020 version of its popular best practice guide for safely using laboratory heating blocks. Used by laboratory scientists worldwide, when utilised properly, heating blocks provide a safe, convenient and productive tool for heating round bottomed flasks, tubes and vials. Typically used in combination with a standard hotplate stirrer - heating blocks are proven to provide superior heat-conducting properties compared to oil baths. They also pose a far lower fire risk and their use makes the clean-up of glassware far easier as there is no residual oil contamination on the outside of the reaction vessel. Today it is widely acknowledged that heating blocks can not only accelerate your chemical reactions - but also ensure that you can work in a safer, cleaner, healthier working environment.
Dr Ffion McKeague, Technology Manager at Asynt, said: “Our original best practice guide was written in conjunction with internationally respected experts from the Department of Chemistry, University of St Andrews and Advanced Chemical Safety Inc. The 2020 Laboratory Heating Blocks - Best Practice Guide has been updated with new improved illustrations and technical data to lead you through best practices for glassware inspection, setting up your reaction, heating your reaction and the post-reaction cool down phase.”

No 971 is an electrically-heated, 500ºF/257ºC class 100 cleanroom cabinet oven from Grieve, currently used to sterilise glassware at the customer’s facility. Workspace dimensions measure 36” w x 36” d x 39” h. 20kw are installed in incoloy sheathed tubular elements to heat the unit, while a 1200 CFM, 1-1/2 HP recirculating blower motor provides horizontal airflow to the workload.
This Grieve cleanroom oven features 4” thick insulated walls throughout and a type 304, 2b finish stainless steel interior with 1/2” inside radius corners, all seams welded, ground and polished. The stainless steel exterior has a #4 brushed finish. The unit is equipped with front and rear access doors for pass-through to the cleanroom plus an integral wall sealing flange. A red pilot light onboard the oven signals when the opposite door is open. All door hardware is chrome plated.
For class 100 cleanroom compliance, this cabinet oven has a 12” x 12” x 6” thick HEPA fresh air filter with 2” prefilter and a 30” x 24” x 6” thick stainless steel high temperature HEPA recirculating filter.
Controls on No 971 include a Minihelic pressure gauge and DOP validation port across each set of filters, digital programming temperature controller, manual
reset excess temperature controller with separate contactors, recirculating blower airflow safety switch, 10” diameter circular chart temperature recorder, fused disconnect switch and an SCR power controller. A stainless steel loading truck with six removable pans and a transfer dolly with oven-to-dolly and dolly-to-truck latches are also furnished with this Grieve oven. More information online:

PRESTO W56 - The New Power Pack With the PRESTO W56, JULABO supplements the PRESTO family with the currently most powerful model within the 1-stage, highly dynamic temperature control systems.
The W56 power pack offers a cooling capacity of 25.8 kW at 20°C and, at 27 kW, has the greatest heating capacity among the 1-stage, highly dynamic temperature control systems of the PRESTO series. With a temperature range of -56°C … +250°C at temperature stability of down to +- 0.05°C, the PRESTO W56 convinces with faster cool-down and heat-up times.
The new W56 is particularly economical due to its high output. The use of the latest thermodynamic technologies supports energy effi ciency by automatically adjusting the cooling capacity to the current power requirement. A new extension kit from the accessories range enables pressure-superimposed temperature control with THERMAL HL30 up to an operating temperature of +150°C.
The PRESTO W56 power pack controls temperatures within reactor temperature control, during material stress tests or temperature simulations with high precision and guarantees extremely fast temperature changes. Thanks to its very high cooling and heating capacity, the W56 is ideal for particularly large, external applications. The magnetically coupled pump allows the pump capacity to be optimally adapted to the application, even over greater distances and heights and in pressure-sensitive applications. Depending on the requirements, the pressure and fl ow rate within the application can be further increased with the booster pump from the range of accessories.
By using highly effi cient components, the PRESTO W56 compensates for exothermic and endothermic reactions even faster. A continuously monitored pressure build- up protects applications and investments. Permanent internal monitoring and self- lubricating pumps ensure a long life-time.
The integrated 5.7-inch industry-grade touch panel
provides a clear and concise presentation of all vital information and thus increases the functionality. Up to eight temperature profi les are freely programmable for automated processes. Modern interfaces support straightforward networking and optimal integration of the devices as well as reliable test monitoring. The sophisticated design offers quick access to the controls and interfaces housed on the front and back.
