The Spinning Flask: A Brief History of Rotary Evaporation

From Ancient Distillation to Modern Laboratory Staple The rotary evaporator has become a ubiquitous tool in modern laboratories. It represents the culmination of decades of innovation in distillation techniques. This seemingly simple device, with its rotating flask and efficient condensation system, has revolutionized the way chemists and scientists process their samples. To fully appreciate its […]

The Truth about Greasing Glass Joints in your Setup

Grease: It protects our bicycles from rust, keeps our doors from sounding like a horror movie soundtrack, and ensures smooth operation of countless machines. But when it comes to the world of rotary evaporators, the question of whether to grease ground glass joints remains a cause for debate. Unless you’re reading this blog post. So […]

Beyond the Muddle: Rotary Evaporation in Mixology

Jerry Thomas and Lyman C. Craig might seem like a really odd pairing: Jerry “The Professor” Thomas, considered the founding father of American mixology, belonged rigidly in the world of bartenders and craft cocktails, while Craig, the inventor of the rotary evaporator, was a respected chemical researcher. In recent years, the boundaries of rotary evaporation […]

How did Pumps with Condensers Become Common?

The Power of Reduced Pressure: Why Vacuum Pumps Matter Vacuum pumps create a low-pressure environment within the rotovap. This pressure reduction lowers the boiling point of the solvent, enabling faster and more efficient evaporation at lower temperatures. This becomes particularly advantageous when working with heat-sensitive samples, minimizing thermal degradation. (We have a whole separate blog […]

Should you Use a Woulff Bottle with your Rotary Evaporator?

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?

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 […]
