Set water bath temperature to 60oC – It does not need to be higher 2The cooling water temperature should be below 20oCAdjust the needed vacuum for a solvent boiling point of 40oC according to list below.

Autoclaves are also known as steam sterilizers and are typically used for healthcare or industrial applicationsAn autoclave is a machine that uses steam under pressure to kill harmful bacteria viruses fungi and spores on items that are placed inside a pressure vesselThe items are heated to an appropriate sterilization temperature for a given amount of timeThe moisture in the steam efficiently transfers heat to the items to destroy the protein structure of the bacteria and spores.
Below is a photograph of a rotary evaporatorImportant Features of the Rotovap1 The vacuum pump is the source of reduced pressure in the system2 Spin speed and bath temperature control knobsPlease do not use the rotovap if the finger is not cold.
Feb 15 2021nbsp018332The rotovap is operated under a vacuum to lower a compound’s boiling point whilst the sample is heated at the same timeWhen the pressure of a liquid decreases the boiling point reduces and the solvent can be vaporized at a lower temperature than their standard boiling pointA cold finger is used to condense the vapors to a liquid which is.
In a previous post we introduced the rule of 20 also known as the 204060 rule or Delta 20 ruleHere we explain the rule in greater detail and discuss how to put it into practice.
In some cases the 204060 version of the rule is taken literallyIn that case you set your bath temperature to 60°C set your coolant to 20°C and then tweak your vapor temperature to 40°C using your vacuum controller.
Jan 01 2015nbsp018332Active MemberWhich is why I believe ethanol coupled with rotary evaporation can be some of the most quotterpene richquot extracts I have personally come acrossI have read elsewhere that ethanol as a polar solvent has the ability to extract more components than a nonpolar solvent such as butane.
Nov 08 2015nbsp018332I recently did a distillation of dicyclopentadiene bp 166 176C to get cyclopentadiene bp 40 176CThe setup as instructed by my supervisor consisted of a simple watercooled Liebig condenser.
Once the flask changes in temperature and becomes cool to the touch lower the mechanism into the water bath or lift the water bath to the evaporation flask depending on the rotovap you are usingMake sure that the solvent level is equal to the water bath levelNever put the flask so low that the Keck clip touches the water.
Our PressureTemperature Nomograph tool is an application of the ClausiusClapeyron equation which assumes the heat of vaporization is a constant over a pressure rangeThe Antoine equation gets around this assumption by using empirical data for each unique liquid under considerationEnter the pressure and temperature in any of five units of.
Small Lowtemp ConstanttemperatureStirring reaction bathIt can replace dry ice and liquid nitrogen to have low temperature reactions and has high precision of temperature controlIt is mainly used for cooling and heating up flasks beakers and tubes and so on and ensuring them constant temperature etc.

Sep 17 2020nbsp018332For imbibers who love the taste of peppers but can’t handle the heat the rotovap allows the bar team to create uniquely flavored distillates and cocktailsEmpirical Spirits Ayuuk made with a rotovapSimilarly at Empirical Spirits a flavorfocused microdistillery in Copenhagen the team uses largescale lowtemperature.
So why are these temperatures advised The main reason for having these guidelines is to help you strike a balance between process efficiency and energy usageDistillation efficiency increases when you have a higher bath temperature and lower coolant temperatureHowever the higher your bath temperature and lower your coolant temperature the more energy you use.
Solvent Boiling Points Chart all boiling points at standard pressure Solvent Boiling Point 176C Solvent Boiling Point 176C Acetic Acid 118.
The most advanced and highest efficiency designed rotary evaporator on the market brought to you by Summit ResearchEasily surpassing all as the king of rotovaps with bone crushing recovery speeds this is the fastest 20 liter rotovap on the marketOnly five main components including roto ball.
The Rotavapor174 R300 meets the highest expectations of convenience and versatility in rotary evaporationIts modular design allows the R300 to be extended to a fully integrated system where a central interface regulates each componentEvaporating flask size 50 – 5000 mLLift mechanism Manual or automaticTemperature range 20 – 220 176C.
The rule of 20 provides a general guideline for the temperatures at which to set your bath and coolantIn general your bath temperature should be 20°C higher than the boiling point of the substance you want to evaporateAnd your coolant should be 20°C or more lower than the vapor temperature.
The standard temperature for an autoclave is 121 degrees CelsiusTo get an idea of how hot this is consider that corresponds to approximately 250 degrees FahrenheitIn other words it is hotter than boiling waterThe reason for this is that simply bringing something up to the temperature of boiling water 100 degrees Celsius 212 degrees.

You want to use the rotovap at room temperature adjust the water bath temperature to 23 degCIf the unit is attached to a positive pressure vacuum unit check that the main pressure valve valve 1 blue valve on the pump valve 2 and the top valve on the rotovap manifold valve 3 are all OFF perpendicular to the line.
You8217ve probably heard of pressure cookers They were all the rage until microwave ovens became popular in the 1980sThey8217re like oversized saucepans with lids that seal on tightly and when you fill them with water they produce lots of highpressure steam that cooks your food more quickly if you want to know more please see the box at the bottom of this pageAutoclaves work in a similar way but they8217re typically used in a more extreme form of cooking to blast the bugs and germs on things with steam long enough to sterilize them.
