We explain the most important factors to consider when shopping for an appropriate chiller, including minimum temperature and cooling capacity.16 February 2019
We examine why rotovap implosions occur, the dangers involved, and what you can do to prevent rotary evaporator glassware implosions and resulting injuries.21 November 2018
We explain the considerations involved when deciding whether or not to use a fume hood with your rotary evaporator, plus offer some alternative options.21 August 2018
I've been asked a few times by customers if we offer rotary evaporator packages - in other words, systems complete with a chiller and vacuum pump. We do, but we do not offer many of them. There are a few good reasons for this, and you should consider these reasons if you're thinking about buying an "out-of-the-box" package.20 August 2018
We explain how a chiller can be jury-rigged and describe the advantages and disadvantages of such a setup.19 July 2018
We reveal why rotary evaporation is more efficient than standard distillation by examining the similarities and differences between the two methods.09 May 2018
Having a chiller not hold its temperature can be detrimental to the application it's being used for and frustrating for the user. We explore the potential reasons your chiller might not be holding temperature to help you identify the issue.18 April 2018
A rotary evaporation system is a complex set of apparatus. Find out about the separate components involved and the role each plays in the overall setup. We cover the rotary evaporator itself, glassware, chillers, vacuum pumps and controllers, and more.17 April 2018
A Woulff bottle can be a useful component in a rotary evaporator setup. Find out exactly what Woulff bottles are and how they're useful in rotary evaporator application.05 April 2018
Creating the most efficient distillation process using your rotatory evaporator doesn't always mean cranking up the speed. We explain the factors involved in choosing the optimal rotation speed for your evaporator to help you set up an efficient system.16 March 2018
Many rotary evaporators come with a choice of coated or standard glassware. We explain some of the benefits of safety coated glassware, address some common concerns associated with its use, and suggest when it should not be used.12 January 2018
Vacuum is an important component of a rotary evaporation system. We explain why a system may not hold vacuum, how to check it for yourself, and what to do if you discover there are issues.19 September 2017
We explore the importance of having a controllable vacuum source as part of your rotary evaporation system. We discuss the practical and safety benefits of evaporating under vacuum versus using heat alone.27 July 2017
When deciding which chiller pump to use with your rotary evaporation system, internal pressure is an important consideration. We explain the need to factor in the maximum pressure of your pump to help ensure you don't end up with broken glassware.
