Q4: What is the main performance of the rotary evaporator?
A: Air tightness is the primary performance of the rotary evaporator, which directly affects the normal operation and life of the rotary evaporator. The airtightness is good or bad depends on the design standard, manufacturing standard and supplier's material selection. Take "actual vacuum degree" and "vacuum pressure holding time" as the standard.
|
|
|
Q5: What is the difference between a glass lift and a bathtub lift?
A: Lifting the bath is safer, because the glass parts associated with the rotary evaporator are less prone to damage and there is no need to lock it after lifting. Glass lifters are mainly suitable for rotating balloons of fixed size. Lifting height is fixed. After lifting, it must be locked.

Q6: What type of vacuum pump is best for a rotary evaporator?
A: A vacuum pump is a prerequisite for a rotary evaporator. We provide SHB-III vacuum pumps for 1L-10L laboratory rotary evaporators, SHB-B95 vacuum pumps for industrial rotary evaporators, and 2XZ vacuum pumps for rotary evaporators, etc. However, better corrosion protection can be provided by using cold traps or other methods.

Q7: How to improve the service life of the rotary evaporator?
A: (1) Please use the operating manual of the rotary evaporator.
(2) After the search is completed, please clean the rotary evaporator in time.
(3) The surface of the rotary evaporator should be kept clean.
(4) If you have any questions about the operation of the rotary evaporator, please contact our experts.

|
Q8: What payment terms do you accept?
A: Usually we accept TT, Paypal, Western Union and L/C. The exact period should be discussed at the time of transaction.
|
|
|
Q9: What is the difference between single-layer and double-layer glass reactors?
A: The single-layer glass reactor can be directly heated or cooled, similar to a water bath or an oil bath, and the temperature control is poor; while the double-layer glass reactor has an intermediate layer between the two layers, we can inject water or oil through the temperature control device to form circulation system, so whether it is cooling or heating, the temperature control performance is better.

Q10: What factors determine the operating efficiency of the evaporator at low temperature?
A: For the same type of equipment, it mainly includes: steam temperature, vacuum degree and cooling water temperature. Because of the thermal instability of certain materials, there may be certain limitations on the operating steam temperature. Therefore, high vacuum and low cooling water temperature are the two main factors to improve efficiency (cryopump can be selected to reduce temperature).
