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.


The left and right side plates, back plate, bottom plate, door plate and drawer plate of the main body are all made of 8mm thick high-quality pure PP (polypropylene) plate, which is resistant

Strong acid-base performance. The top edge is widened and stable, and the load-bearing performance is better. The butt joints are all welded with the same color welding rod by professional manual seamless welding.

It is resistant to strong acid and chemicals, impact resistance, no corrosion and no rust.

The table top is made of 8mm thick high-quality pure PP (polypropylene) board with strong acid and alkali resistance, or solid physical and chemical board (12.7mm thick) is used.

Impact resistance, corrosion resistance, formaldehyde to reach E1 level standard.

All the internal connecting devices of the connecting part shall be hidden and corrosion resistant, there shall be no exposed screws, and the external connecting devices shall be corrosion resistant.

Learn to corrode stainless steel parts and non-metallic materials.

The overall color of the cabinet body is porcelain white, the handle and hinge are blue, and the test bench is composed of a single unit cabinet body with double cabinets and single cabinets.

Cabinet, water cabinet, main cabinet, vacancy, keyboard, single draw, etc., can be customized in size.



The slide rail adopts a self-sliding system with the same cabinet material PP board device, which is smooth and free, has good load-bearing and long service life, and has strong acid and alkali resistance.

Good corrosion performance, no metal and other parts.

The hinges, beads and screws are made of PP material with good performance such as strong acid and alkali resistance, and the cabinet door opening angle is 180 degrees.

The handle is made of the same cabinet material PP board, and the handle is U-shaped pockmarked surface.

One maintenance window is reserved for the back plate of other cabinets to facilitate troubleshooting.


It has beautiful features, easy disassembly and assembly, overall high temperature resistance of less than 100 °, corrosion resistance, no rust, and long service life. It is the best choice for chemical laboratory configuration.
