Lab equipment is used to test, analyze, sterilize, and preserve materials in professional laboratory environments. Autoclaves and sterilizers, ultrasonic cleaners, and labware washers clean instruments, parts, and equipment to help reduce contamination during experiments.
Evaporation. Evaporation requires heat (or air movement above the sample) to drive off a volatile solvent. If the substance is a solid mixed in a solvent, begin by filtering (or decanting). If the substance is dissolved in a solvent, then use crystallisation.

using a rotary evaporator. Preparation of the orange precipitate was similar to the red, except that 15 g of creatinine were dissolved. During the acidifi-cation step, the concentrated acid was added very slowly. Cry-stals were separated by filtration of the cold solution and dried in the rotary evaporator. Z. Klin. Chem. Klin.

About 20 mL of acid was added to the benzoate solution to pass the endpoint of the titration. The 2-naphthol took much more than the estimated amount of acid to complete the precipitation. . The rotary evaporator was used to evaporate the diethyl ether from the naphthalene mixture. The flask containing the naphthalene was also left to air dry .

A rotary evaporator is a device used for the efficient and gentle removal of solvents from samples by evaporation. Our LABOROTA Digital Rotary Evaporator with digital display and heating bath for water or oil (temperatures up to 180°C) is ideal for more complex distillations requiring insight into process parameters. The digital rotary .
A rotary evaporator (or rotavap /rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was .
Objective: To establish a testing method for determination of acid and peroxide value in nuts by potentiometric titration. Methods: The nuts samples were extracted by the petroleum ether, the reagent after filtration was recycled with the rotary evaporator, the acid and peroxide value of the extraction of oil were tested by potentiometric titration, and then the results of acid and peroxide .

The Heidolph Laborota 4001 Rotary Evaporator comes with a gliding heating bath, attached to the main body of the rotavapor, but with independent controls. The interior of this rotovaps heating bath is insulated to help maintain temperature, with a nonstick coating for easy clean up, and encapsulated elements to prevent scalding.
CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF EVAPORATORS. Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration, process. We define the evaporation process as one that starts with a liquid

Rotary evaporator is widely used in the laboratory. In addition, as an ideal equipment, it plays an important role in many fields, such as: chemical industry, medicine, pharmacy, food industry and biology.The rotary evaporator is controlled by current to make the flask run at a constant speed.Inside the flask frame, a motor can be used for lifting and lowering.
• In the event of solvent spillage open the windows to aid evaporation. If a spillage is serious, immediately evacuate the lab., and seek assistance from the lab. technician, or your supervisor • In the event of a water leak remove the apparatus from the heat source and turn off the water supply.
Nowadays, the rotary evaporator are widely used in factories and laboratories, It is mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. However, there are many problems during the distillation process. For example: lower distillation effect, distillation collision and so on.
