A rotary evaporator is a device commonly used in chemical laboratories for the efficient and gentle removal of the volatile solvents from samples by evaporation. They are found in almost every organic laboratory. The rotation flask rotates and shapes a thin film in negative pressure condition by heating; it evaporates; and then the vapor is condensed, liquefied, and recollected for separation.
A jacketed vessel is a container that is designed for controlling temperature of its contents, by using a cooling or heating “jacket” around the vessel through which a cooling or heating fluid is circulated. The jacket has ability to permits the uniform exchange of heat between the fluid circulating in it and the walls of the vessel.
Freeze drying, also known as lyophilization or sublimation, they are synonymous. Freeze drying is a low temperature dehydrate process that typically used to preserve perishable materials, to extend shelf life, or make the material more convenient for storage or transport. Freeze drying works by freezing the material, then reducing the surround to allow the frozen water(ice) to sublimate.
Freeze drying has been used in a number of applications for many years, most commonly in the food and pharmaceutical industries. There are, however, many other uses for the process including the stabilization of living materials such as microbial cultures, preservation of whole animal specimens for museum display, restoration of books and other items damaged by water, and the concentration and recovery of reaction products.
Single layer glass reactor is composed of a mechanical part, the governor, the heating portion and the glass part of the four major components of its structure. The key pieces of machinery parts, main pole, chassis, etc made of high quality stainless steel shell, with good corrosion resistance, high temperature resistant glass blocks all with borosilicate glass production.
Molecular distillation is a special liquid liquid separation technology, operating under extremely high vacuum.He is according to,the molecular motion of a different material has different mean free path of the physical characteristics and achieve the purpose of separation,and the liquid at a temperature below the boiling point will be the separation,and is especially suitable for the separation of high boiling point,heat sensitive and easily oxide system.
