Product Introduction
20L Rotovap is commonly used in scientific research and development, process optimization, and industrial production.A 20L Rotovp is a laboratory device used for efficiently removing solvents from liquids through evaporation. It is a flask-based evaporator that is typically designed to hold 20 liters of liquid. The flasks rotate during the evaporation process, which helps to mix the liquid and improve heat transfer, leading to faster evaporation times.
The structure of a 20L Rotovep typically includes a motorized base that houses the drive train and speed controller for the flasks. The flasks themselves are made of glass or high-quality plastic and are designed to fit snugly into the base. The flasks have a conical bottom that allows for easy draining of the remaining liquid after evaporation.
The heating elements that provide heat to the flasks are typically located around the base and are designed to transfer heat efficiently to the flasks and the liquid contained therein. The entire assembly is typically covered by a protective cover to keep any foreign objects from entering the unit and interfering with the evaporation process.
The materials used in the construction of a 20L Rotovep vary depending on the specific model and manufacturer, but typically include high-grade stainless steel, glass, and plastics that can withstand the high temperatures and corrosive solvents often used in laboratory evaporations. The motorized base and heating elements are typically made of sturdy metal alloys that provide long-term durability and reliable performance.
Product Parameter
► 20L Rotovap: It is a laboratory instrument used for evaporating and concentrating liquids in scientific research and development, process optimization, and industrial production. Its common parameters mainly include the evaporation rate, the evaporation time, the stirring rate, the heating power, the flask capacity, and the materials of the flask and the rotor.
► Evaporation rate: It refers to the rate at which the solvent in the liquid is evaporated per unit time under certain temperature and pressure conditions. The evaporation rate of Rotovep is generally between 0.01 and 5 ml/min. The evaporation rate can be adjusted by controlling the heating temperature and the stirring rate of the flask.
► Evaporation time: It refers to the time required for evaporating all the solvent in the liquid. The evaporation time of Rotovep is generally between 0.5 and 2 hours, but can also be adjusted according to different experimental requirements. The shorter the evaporation time, the higher the production efficiency, but it also needs to consider whether the evaporation time is long enough to avoid too much heat causing damage to the liquid.
► Stirring rate: It refers to the speed at which the flask is stirred during evaporation. The stirring rate can be adjusted between 0 and 1500 rpm. The stirring rate can improve the heat transfer performance between the liquid and the flask wall, so as to improve the evaporation rate and uniformity of the remaining solution after evaporation.
► Heating power: It refers to the maximum heating temperature of Rotovep under maximum heating power. The heating power of Rotovep is usually between 50 and 600 W, which can be adjusted according to different experimental requirements. The higher the heating power, the faster the evaporation rate, but it also needs to consider whether too much heat will cause damage to the liquid or affect the quality of the remaining solution after evaporation.
► Flask capacity: The standard capacity of Rotovep flask is usually between 50ml and 500ml, but there are also some Rotoveps with flask capacity between 1000ml and 2000ml, which can meet different experimental requirements. The greater the flask capacity, the greater the amount of liquid that can be processed at one time, but it also needs to consider whether there will be sufficient heat being transferred to the liquid to ensure a reasonable evaporation rate.
► Materials of flask and rotor: Rotovep flasks are made of glass or high-quality plastic materials that are chemically inert and can withstand high temperatures and pressures. Rotor is made of stainless steel or other wear-resistant materials, which can ensure long-term use and reliable performance. The materials used in Rotovep flasks and rotors have a significant impact on their mechanical strength, chemical inertia and heat resistance, which will ultimately affect Rotovep's performance and longevity.
In short, it common parameters have different effects on its performance and longevity, so it is necessary to choose appropriate parameters according to different experimental requirements to ensure Rotovep's good performance and longevity.
