The Woulff bottle, a seemingly simple piece of glassware, is a two-necked bottle (which also has a three-necked variant) first described by Peter Woulfe (1727-1803). In this blog post, we’ll delve into the world of Woulff bottles, exploring their design, applications, as well as both the advantages and disadvantages of using them in your lab […]
What are Azeotropes? An azeotrope is a liquid mixture with a unique feature: its vapor phase possesses the same composition as the liquid phase at its boiling point. This means that boiling an azeotrope does not alter the relative concentrations of its components. Unlike typical mixtures where the more volatile component evaporates first, azeotropes boil […]

In today’s no-holds-barred blog post, we’ll be facing off rotary evaporation and classical distillation: the different advantages each one presents over the other, and the key differences in efficiency, the process itself, the equipment used, and applications. Some of the advantages of using rotary evaporation 1-Faster Evaporation: One of the primary advantages is the […]
When using your rotary evaporator, you are at a constant risk of glassware implosion. In this blog post, we’ll go over the different reasons why glassware implosions occur, the different dangers that are involved, and the different mitigative measures that you can undertake to prevent or reduce the risk of glassware implosions. Why does rotary […]
In rotary evaporation, as in a lot of other things happening in your lab, time is of the essence. Maybe you need those APIs purified ASAP, or maybe your clients needed that ethanol removed from the cannabis they sent you yesterday. Bottom line is a rotary evaporator can only spin so fast, but we got […]
It is a common occurrence for samples being evaporated in a rotary evaporator to foam up, or starting bumping. This usually leads to sample loss, and possibly contamination. Foaming occurs when the sample’s surface tension decreases, leading to the production of bubbles. Bumping however refers to the sudden and vigorous release of vapor bubbles from […]
Years after “Star Wars: Episode 1 – The Phantom Menace ” was released, George Lucas revealed that the title was a reference to Palpatine concealing his identity as an evil Sith Lord behind the façade of a good-willing public servant. And while dry ice slurries aren’t nearly as evil as Sith Lords, they do pack […]
Don’t worry about the dry ice supply chain going dry – with Ecodyst If you’ve been keeping up with logistics news, you might have heard of the dry ice supply chain, and how it’s taken a significant hit during the COVID-19 pandemic: with vaccines requiring temperatures as low as -70°C during transport and storage, the […]
Using a vacuum source with your rotary evaporator comes with a significant set of advantages, like making your processes safer, more efficient, cleaner, and overall, easier. In this blog post, we’re going through all the reasons why owning a rotary evaporator is typically paired with using a vacuum source (either built-in or a vacuum pump). […]
