There are many brands of rotary evaporators with different quality. Some of the instruments of the same model with the same function have very different prices.
1. Sealing ring: the service life of the rotary evaporator is determined by the airtightness. The rotary evaporator needs to be kept in a vacuum state when working. The wear-resistant and corrosion-resistant sealing ring is the key to ensure the airtightness. The rotary evaporators produced by Linbel Instrument are double sealed with PTFE and fluorinated rubber, which are corrosion resistant, zero pollution, and can maintain a high vacuum state, effectively extending the service life of the equipment and reducing the replacement frequency of the seal ring.
2. Glass: The condenser and rotary bottle on the rotary evaporator are all glass products. The thickness and density of glass sheet directly affect the overall quality of the instrument. All glass components produced by Linbel Instrument are made of GG-17 raw materials. The performance of GG-17 heat-resistant glass fully conforms to ISO3583 international standard. The internal structure of the glass body is stable and can withstand high temperature difference.
3. Motor and controller: the Linbel Instrument adopts DC brushless motor, which can work continuously for a long time, with high power and low noise. Control electronic stepless speed regulation, rotation control, temperature digital display, intelligent temperature control. The temperature sensor has fast temperature transmission, high accuracy and temperature difference of ±1℃.
4. Heating pan: the heating pan is made of 304 stainless steel, which can be used for both water and oil, and has a wide temperature range.
5. Other price factors: such as electric lifting or manual lifting, whether there is a vacuum meter, whether there is a valve in the feeding pipe, whether there is a discharge valve in the collecting bottle, etc.
