Product Details

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.

Product features: XD-52AA(RE-52AA) type rotary evaporator, the main metal parts are made of stainless steel, rust-proof aluminum alloy, compact structure, exquisite appearance, durable, and strong practicability. The sealing system adopts fluorine glue double PTEF imported material and glass rotating shaft Combination, no slag, wear-resistant and extend the service life.

Temperature range: room temperature -99 ℃. The temperature is higher than the set temperature heating tube automatically stops heating. 4L water bath pot adopts one-time forming SUS304 Teflon composite pot, which is easy to clean.
