Manual Rotary Evaporator

Manual rotary evaporator



1. Uses:
The device through electronic speed control, the flask in the most appropriate under the constant speed of rotation, under the vacuum in the heating temperature, so that proliferation of evaporation of the solution bottle, and then condensation solvent recovery. Is a biological, pharmaceutical, chemical, food, higher institutions and scientific research, laboratories and other units for the concentration, crystallization, separation, recycling and other essential equipment ideal.


2. Main technical indicators:
1. Host speed :0-150 r / min, electronic variable speed. (RE-52B :0-100 r / min).
2. Vacuum: 0.096MPa above.
3. Maximum lifting distance: 150 mm. (RE-52B 200 mm)
4. Power Supply: AC 220V 10%, 50HZ, input power 1KW. (RE-52B 2KW)
5. Dimensions: 370 530 750 (length width height). (RE-52B 550 490 730)


3. Features:
1. Is simple with automatic up and down lifting devices, touch up the host keys up, down button touch down console, hand-off button that stops, easy to operate. Another available emergency hand wheel, when the lift motor failure will hand wheel rotation, the host can increase or decrease.
2. A unique seal structure and selection of sealing materials, vacuum good performance.
3. Temperature from the digital display, control achieved by the metal probe sensor, when the sensor into heating tank (water bath), the water temperature to the temperature of the power will automatically cut off the heater when the water temperature below the selected temperature will automatically be connected heating power, so turn to control the temperature, constant temperature. dipswitches 100 temperature controller to set the median "O" position.
4. Heating use high-quality stainless steel tank, 220 120 diameter cylinder, a heating power of 1KW, closed-end resistance heater can be installed 2L flask pot rotation. (RE-52B 280 180 , 2KW, 5L flask )
5. High evaporation rate of the vertical condenser system, walls are hunting two-loop cooling water pipes made of glass. When the rotating flask, the solution evaporated in the inner spread, and then evaporation of large diameter pipe into the large diameter condenser tube to speed up evaporation.
6.RE-52B, RE-52D use all stainless steel, corrosion-resistant, high-quality utility.


4. Installation
1. Installation angle of the first adjustment of the nose, as long as the right to send the boot lock wrench head can be adjusted, usually to the right under the slope of 30 or so, when adjusting the other hand to lift up the nose, must be locked after adjustment. and support the fixed plate (14) installed in the head on the left (the factory to install good), then vertical bar in (14), temporary and do not tighten screws.
2. Spindle (1) Installation: each port interface, and the sealing surface grinding, seals must be cleaned, painted before installation, require a layer of vacuum grease to prevent leakage. The nut (2) The first set of the spindle (1) on , then clamping ring (3) sets of slots cut into the shaft Shen Department (to be embedded in the grooves), and Qian into the spindle sleeve (4) within the screw on the nut (2) then a small hex wrench (5) Qian people The search for sunken hole in the head following hole then tighten (2), looking for rotation with the other hand when the nut (2), to wrench Shen holes then tighten (2), so that spindle lock Instead you can remove the spindle. or rotation (2) spindle sleeve (4) follow the turn.
3. Stone bottle (11) installation: the large plastic nut (9) the first set into the four-way bottleneck, then spring ring (10) is also set into bottlenecks, the bottleneck on the side of the card firmly, and then press install map to Seal Block (7) sets in (1), the PTFE "8. Four Fluorine...... Enclose seats in type" circle seat (8) sets in (1), the last bottle on the Stone large nut screwed into the nose.
4. Condensate bottle (16) Installation: First put on stainless steel support clip ring (18) to (16) Qian (11) the mouth, and rotate in close contact with what made the interfaces at this time (18) set into the vertical bar ( 15), the adjusted position after (14) and tighten the screw. mounted on the vacuum port connector (17).
5. Feeding tube (12) and the deflation switch (13) the factory has been fitted together, turn the handle 90 degrees to play a role in closed or open, and finally install the evaporator liquid bottles and bottle collection and use clamps.

6. Nose threaded flange 7. Sealing seat 8. PTFE -ring seat 9. Large plastic nut
10. Spring ring 11. Stone bottle 12. Feeding tube 13. Deflation switch 14. Support the fixed plate 15. Vertical bar
16. Condensate bottle 17. Vacuum connector 18. Support clamping 19. Insurance screws (RE-52B are equipped)


5. Usage:
1. Height adjustment: manual lifting, rotating machine column above the hand wheel, cis to rise, reversing the decline. Electric lift, touch up the host keys up, down button touch down the host.
2. Condenser has two external connectors are then used in cooling water, a water access, the other head on the water, usually running water, condensing water temperature, the lower the better. Mounted on the vacuum port connector, then vacuum skin vacuum tubes used.
3. Start before the first speed control knob to the minimum L, press the power switch indicator light, and then slowly to the right at the required speed, generally large evaporating bottle, the low speed, a lower viscosity solution speed. flask is a standard interface, 24, were attached to 500ml, 1000ml two flasks, liquid volume is not more than 50% fit.


6, note:
1. Glass parts tipping should be gently, before loading washing clean, dry, or drying.
2. The grinding mouth, sealing surface seals and joints are needed before installing a layer of vacuum grease coating.
3. Heating tank water before power does not allow water and dry.
4.RE-52B must be made (of 19) screwed into the hole insurance, the insurance, so as not to damage the flask.
5. Such as vacuum and do not need to check up
(1) the connector, the interface is sealed
(2) ring, the sealing surface is valid
(3) vacuum grease between the spindle and the ring is coated well
(4) vacuum pump and the skin tube air leaks
(5) whether there are cracks in the glass cases, fragmentation, damage to the phenomenon of
