Rotovap is the mani products of ZZKD,from the type, it is divided into large scale rotovap and small scale rotovap,the capacity include: 2L rotary evaporator, 5L rotary evaporator, 10L rotary evaporator, 20L rotary evaporator, 50L rotary evaporator,etc.
Pay attention to the safety of use during the use of the rotovap.Rotovap has not only become the standard configuration of laboratories in the pharmaceutical, chemical and biopharmaceutical industries, but also play a great role in the processing of high-value samples.Because the use of liquid and vacuum heating makes the rotovap a safety hazard in the laboratory, many people regard additional safety features as the most important condition.Let me introduce to you how to ensure safety when using a rotovap.

In traditional distillation equipment, the distilled liquid medium can only reach the heat source at the wall of the distillation vessel.This contact may cause overheating and make the boiling evaporation process uncontrollable; this will also bring safety hazards to equipment and personnel.At the same time, too high temperature will also affect product quality or all samples will be scrapped.The vacuum (boiling and evaporation at low temperature) and rotation (to avoid overheating) of the rotary evaporator can completely control the removal process of the diluent.

The company uses polytetrafluoroethylene and rubber composite seals to maintain high vacuum; high-efficiency condensers ensure high recovery rates;Digital constant temperature control of water bath; reasonable structure and careful use of materials;The mechanical structure adopts a large number of stainless steel and aluminum alloy parts;All glass parts are made of high temperature resistant high borosilicate glass;
1.About the degree of vacuum:

The vacuum degree is the most important process parameter of the rotary evaporator, and users often encounter the problem that the vacuum degree cannot be hit, which is often related to the nature of the solvent used.The biochemical pharmaceutical industry often uses acetic acid, ethanol, propanol, ethyl ester, ethyl ether, petroleum ether, chloroform, water, toluene, etc. as solvents, but general vacuum cannot withstand strong organic solvents, and you can choose a special vacuum pump with strong corrosion resistance first. (Recommended to use circulating water vacuum pump)

2.About the temperature rise of the motor

The motor adopts E-class insulation, and the winding adopts polyester high-strength enameled wire.The operating environment and altitude do not exceed 1000 meters, and the ambient temperature does not exceed 40°C,Continuous use of the motor surface temperature rise does not exceed 45 ℃ is normal, can be used with confidence.If the temperature rise exceeds 45℃, check the relevant transmission lubrication system. If the ambient temperature is very high and the temperature of the water bath is also very high, the user can use a fan for cooling.

Heating mantle: Use deionized water or low-viscosity clean silicone oil to change weekly.
Glass components: The glass ground joints are cleaned with ethanol every week and vacuum silicone grease is applied.
Sealing ring: It is recommended to check the wear of the sealing ring quarterly (the vacuum value can be used to judge).
Host: Keep the shell and panel dry.
Cleaning: Please disconnect the power when cleaning and maintaining the instrument. Please use detergents containing surfactants or use isopropyl alcohol to clean inert stains.
