Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

Rotary evaporator RE2000-Pro

Product features:

The large LCD digital display screen can display temperature and speed at the same time, which is convenient for the optimization control of the distillation process;

When the power is cut off accidentally, the motor will automatically lift the evaporation bottle to a safe position above the heating pot;

5L water, oil bath dual-purpose heating pot, heating temperature up to 180°C, water, oil bath two heating mode switching is convenient;

When the temperature reaches 220°C, start the overheat protection;

When there is no water or oil in the heating pot, the power supply will be cut off automatically to start the protection against dry burning. The rotating speed range is 20 -280 rpm, which can be carried out alternately in forward and reverse rotation;

Condenser (condensation area 1700 cm2), excellent condensation effect;

The microprocessor accurately controls the temperature of the heating pot and has an over-temperature protection function; the evaporation bottle has an ejector for easy disassembly;

Double-layer modified PTFE high elastic sealing ring and compression spring design, excellent sealing performance; Optional explosion-proof glass;

Optional rotary steaming protective cover set, can be easily installed on the heating pot to prevent high temperature liquid splashing, to protect the safety of the operator;
