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:

Ball milling mouth condenser tube, fast cooling and recovery, quick installation and disassembly;

Feeder: valve type feeding pipe is connected with Teflon pipe and water retaining ring:

Integrated control panel, stable speed, accurate temperature;

One-time forming 4L Teflon composite pot, corrosion resistance, fast heating, easy to clean:

Manual, automatic dual-purpose lifting function easy to operate:

Temperature and speed are displayed on the same screen: the shaft combination does not drop slag and is wear-resistant to extend the service life:

Sealing parts: fluorine glue double PTEF imported materials and glass;

The main metal parts are made of stainless steel, rust-proof aluminum alloy, compact structure, high precision, durable.

The equipment has a protective cover (heat preservation, energy saving, splash proof, explosion proof).
