R-1020EX large-scale Rotary evaporator is a large-capacity, large-diameter swirl/spin evaporation equipment with a large evaporation area. The instrument achieves effective evaporation of the solvent by placing the swirl/spin bottle in a bath, heating it while swirl/spin, and cooperating with a pressure-reducing device. In order to meet the conditions of use in explosive gas environments, this model specially adopts an explosion-proof design protected by a flameproof shell "d", which is suitable for pilot tests in the fields of biology, chemical industry, food, etc. It can be used with circulating water-type multi-purpose vacuum pump, diaphragm vacuum pump, circulating chill down device, thermostatic circulator, Cryogenic coolant circulating pump and other supporting devices.
1. Adopt "Teflon + FV rubber, fluorinated rubber double sealing ring" technology to ensure the negative pressure index. 2. Equipped with an automatic switching valve, it can be continuously collected without affecting the negative pressure index of the system and solvent distillation. 3. Teflon discharge valve, corrosion resistance, no pollution. 4. The motor, heating device, and electrical control box are all explosion-proof, and the Explosion-proof level is DII BT4. 5. The electrical control box is installed independently for easy operation. 6. A protective cover is provided outside the bath to prevent burns. 7. One stretch forming 304 bath, corrosion resistance.
When the instrument is working, the large-capacity swirl/spin bottle containing the sample is placed in the heating bath, and the swirl/spin bottle is driven by the motor at a constant speed swirl/spin to increase the evaporation area. At the same time, the bath heats the sample and cooperates with the vacuum system to reduce the system pressure, so that the solvent evaporates quickly at a lower temperature. The evaporated solvent vapor is condensed by a high-efficiency condenser pipe (vertical, main cooling + auxiliary cooling, effective three-return flow) and flows into the collection bottle. Through the automatic switching valve design, the continuous collection of solvents can be realized.
Pilot tests in the fields of biology, chemical industry, food, etc
Explosion-proof level Exd ⅱ BT4
1. Place the instrument in a stable and well-ventilated environment, and connect the vacuum, chill down and other supporting devices. 2. Fill the sample to be evaporated into a 20L swirl/spin bottle and install it on the instrument main unit. 3. Set the heating bath temperature (RT +~ 99 ℃) and swirl/spin speed (20~ 130rpm) according to the boiling point of the solvent. 4. Turn on the vacuum system to achieve the required Vacuum Level. 5. Start the heating and swirl/spin function to start the evaporation process. 6. During the evaporation process, the condensed solvent can be continuously collected through the automatic switching valve. 7. After the experiment, turn off the heating, swirl/spin and vacuum systems in turn. After the system returns to normal pressure, remove the swirl/spin bottle and the collection bottle.
• This instrument is explosion-proof equipment, motor, heating device, electric control box Explosion-proof level is Exd ⅱ BT4, need to meet the Explosion-proof level requirements of the explosive gas environment. • Operating Environment Temperature should be in the range of 5~ 35 ℃. • Before operation, make sure that the instrument is well grounded and the electrical connection (3~, 380V, 50Hz) is correct and reliable. • There is a protective cover outside the heating bath, but you still need to pay attention to high temperature during operation to prevent burns. • The lifting mechanism is manually operated, the lifting Travel is 0~ 190mm, and the operation needs to be stable. • The bottom of the instrument is equipped with a lockable caster. Please lock the caster after moving it in place to ensure stability. • Regularly check the integrity of PTFE + Teflon-fluorinated rubber double swirl/spin sealing and arc-coated fluorine flange sealing to ensure Vacuum Level (vacuum system boost rate ≤ 2kPa/h). • Do not use medium that has strong corrosion to 304 stainless steel bath. • Please disconnect the power supply during cleaning and maintenance. • Do not exceed the Maximum capacity of the swirl/spin bottle (20L) and collection bottle (10L).
