1DESCRIPTION

Produced by Shanghai Bono Biotechnology Co., LtdBIONOON-VRFVacuum concentration freeze dryer, both its vacuum centrifugal concentrator and vacuum freeze dryer are "Bono"BIONOON”Brand, using independently developedBIONOONThe operating system provides unified control, making device interfaces and software compatible and easy to operate. A set of instruments can not only run simultaneously to solve the dual needs of sample freeze-drying and centrifugal concentration. At the same time, it can also be operated separately for freeze-drying or centrifugal concentration of samples, which can be said to kill two birds with one stone.This instrument combines the dual advantages of high-throughput small volume sample vacuum concentration and large volume sample freeze-drying, with a wide range of applications, and can solve the concentration of thermosensitive samples, general laboratory samples, and freeze-drying. satisfiableRNA/DNAProtein and other thermosensitive samples require low-temperature concentration, while also meeting room temperature concentration requirements. The temperature control range is wide, and the chamber temperature can be supported-10℃~100℃, different types of rotors can be selected according to the sample size during useEPTube, glass test tube, various centrifuge tubes, chromatography bottles, centrifuge bottles or96Orifice plates and freeze-drying bottles, etc.

IIWorking principle

1.The working principle of the concentration system: When the pressure decreases, the boiling point of the solvent also decreases. When the pressure drops to a certain level, the solvent can boil and evaporate under relatively low temperature conditions. In order to avoid sample evaporation and cross contamination, high-speed centrifugal rotation technology is used to ensure that the sample is in the sample tube and will not spray out.

2. Working principle of freeze-drying system: The freeze-drying principle is mainly based on the three state change law of substances. When a substance reaches a certain level at low temperatures, its molecular motion slows down and forms a solid state. In a vacuum environment, the influence of external pressure on water molecules decreases, and the intermolecular distance increases, allowing water molecules to sublime directly from the solid state to the gas state, achieving the purpose of drying. This drying method can preserve the original nutritional content and color of the material, while avoiding the oxidation and deterioration of some heat sensitive substances.

3、 Application scope

This set of instruments is suitable for fields such as medicine, pharmaceuticals, biological research, chemical engineering, and food. Samples processed by centrifugal concentration and freeze-drying are easy to store for a long time, and can still maintain their original biochemical characteristics after solvent recovery.
