Today we bring you a new product, PFA rotary evaporator, we believe you have seen many in the market, so what is the difference between our rotary evaporator? how should we choose? whether it meets my experiment? Let’s talk about them!
How to choose?
1. What is the capacity of the rotating bottle of the evaporator?
2. Choose electric lift or manual lift?
3. The fastest speed should be 130, 150, 200, 310 rpm? (Crystal powder experiment requires high speed, is it necessary to have forward and reverse function?
4. Do high boiling point materials need oil bath heating? What if you choose a water bath for ordinary experiments?
5. Does the experiment involve acid and alkali, especially hydrogen fluoride, and glassware cannot be selected. Does the experiment have requirements for the purity of the container? (Is the experimental material easy to boil?) Do you need a vacuum controller? Do you want a timer function?
6. How much is the experimental cost budget?
7. The vacuum pump must be equipped (ordinary circulating water vacuum pump or anti-corrosion diaphragm vacuum pump is required), and it is recommended that users be equipped with a low-temperature cooling system for extraction experiments!
8. Does the distillation of flammable reagents require a host with a high safety factor?
What’s different about our rotary evaporators?
Binglab’s rotary evaporator is made of Teflon material, and the parts in contact with the sample are all made of PFA. I believe that customers who have learned about PFA material know that it is resistant to strong acids and alkalis, organic solvents and high temperatures, and has low background value. Dissolution and With less precipitation and less metal ion impurities, it is a kind of plastic container that is a better choice for experiments. This material has high transparency, and the reaction of the solution can be seen.
Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries. The principle is to heat at a constant temperature under vacuum conditions to make the rotary bottle rotate at a constant speed, and the material forms a large-area film on the wall of the bottle to evaporate efficiently. The solvent vapor is cooled by a high-efficiency glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency.
