The molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation relying on the difference between boiling points. This is a kind of process of distilling and purifying the heat sensitive material or high boiling point material by making use of the difference of material molecular movement free path in high vacuum degree. The molecular distillation is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics, oil and other fields.
This Molecular Distillation has the following advantages
High evaporation efficiency, reducing retention time; with minimal time delay
The high precision glass tube allows the liquid to form a complete integrated film on the heated surface;
The MD molecular distillation system consists of borosilicate glass and PTFE and SS316L, so it has excellent corrosion resistance;
The stirring motor system adopts magnetic stirring system, no noise, higher stirring speed and faster film forming speed;
The squeegee film forming system is made of PTFE material and 316L, which has higher corrosion resistance;
the system's maximum temperature can reach 230 C;

RE-100L rotary evaporator is mainly used in the concentration, crystallization, drying, separation and solvent recovery of pharmaceutical, chemical and biological pharmaceutical industries. Its principle is: under vacuum condition, constant temperature heating makes the rotary bottle rotate at constant speed, and the material forms large area film on the bottle wall, so it can be evaporated efficiently. The solvent evaporation is cooled by the high-efficiency glass condenser and recovered in the collecting bottle, so as to greatly improve the evaporation efficiency. The utility model is especially suitable for concentrating and purifying biological articles with high temperature and easy decomposition and degeneration. Applications of the RE-100L Rotary evaporator RE-100L rotary evaporator is mainly used in the concentration, crystallization, drying, separation and solvent recovery of pharmaceutical, chemical and biological pharmaceutical industries.
Brief Introduction of the Jacket Glass Reactor The series of reactor kettles is my company according to the actual requirements of customers and the standard production of new double glass reactor with cylindrical glass reactor body, which absorb the international and domestic advantages of similar products, while bold and innovative, not only easy to use one can easily move, , And the structure of innovative and practical, beautiful appearance generous, leading domestic; for modern chemistry, fine chemicals, bio pharmaceuticals, new materials, such as the synthesis of experimental and production of the ideal equipment. Specific specifications from 1L to 200L optional. The working principle of the series reactor: double layer glass reactor inside the reaction material, but also can be vacuum to do the stirring reaction; sandwich can be connected to heat water, water or hot oil or electric sets to do heating or cooling; The reaction solution was controlled to evaporate and reflux. Jacket Glass reactor principle is two parts, in the inner glass,the mix bar is continous stirring to make mixing or evaporating reaction under negative vacuum pressue. The stirring is under speed controlling. The jacketed glass could supply heating or cooling material to help the chemical reaction. Recently glass reactors has been widely used in chemical, biological and pharmaceutical experiment and prodcuction.

Introduction: 4-hydroxyethyl piperazine ethosulfonic acid (HEPES) is an important hydrogen ion buffer, which has a good buffer ability in the pH range of 6.8 to 8.2, and can control a constant pH for a long time. Using a concentration of 10 ~ 50mmol/L, the general culture medium containing 20mmol/L 4-hydroxyethyl piperazine taurine can have a good buffer capacity, and has no toxic effect on cells. Application: HEPES (4-hydroxyethyl piperazinethesulfonic acid) is a non-ionic amphoteric buffer with high polarity, and is inert to a variety of chemical reagents and enzymes. It does not participate in and interfere with the process of biochemical reactions, and has no inhibitory effect on enzyme chemical reactions. Therefore, it can be used specifically for the research of proteins and enzymes that are highly volatile and ph-sensitive to organelles and very volatile. Buffer solution preparation: (1)hepes buffer can be directly added to the prepared culture medium according to the desired concentration, and then filtered to remove bacteria. 2.38 g HEPES was added to each 1000ml of culture medium, the pH was adjusted to 7.2 with lNNaOH after dissolution, and the bacteria were removed by filtration before use. At this time, the concentration of HEPES was 10mmol/L. (2) 100x storage solution (lmol/L) could also be prepared. Before use, 99ml culture solution was added to lml storage solution, and the final concentration was 10mmol/L. lmol/L (100x) hepes buffer was prepared as follows: 23.8gHEPES was dissolved in 90ml double distilled water, the pH was adjusted to 7.5-8.0 with lNNaOH, and then the water was fixed to 100ml, filtered to remove bacteria, divided into vials (2ml/ bottle), and stored at 4�ºC or -20�ºC. Purpose: 1.Biological buffer; Reaction buffer, prehybridization buffer and hybridization buffer for isolation and analysis of RNA nuclear fraction; For RNA with T4RNA 2.Molecular biology grade is used for RNA3' -end labeling with T4 RNA ligase 3.Cell-cell adhesion, short-term cell aggregation culture, cleaning of tissue and cell buffer
