1. Product introduction

The circular solid phase extraction device JC-GX-24S allows the liquid sample solution to pass through the adsorbent, retains the substance to be tested, and then selects an appropriate strength solvent to flush out impurities, and then quickly elutes the substance to be tested with a small amount of solvent, so as to achieve rapid separation Purification and concentration purposes. At present, it is mainly used in the analysis of organic substances such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in water, and the analysis of fruits, vegetables and herbicide residues.

2. Product parameters

1. Number of samples: 24

2. Control method: independent control

3. Pressure display: there is a pressure gauge

4. Vacuum degree: 0.098Mpa

5. Flow control valve: 24

6. Work area size: ∮240X138 (mm)

3. Product Features

1. The whole machine is made of transparent plexiglass, with strong corrosion resistance.

2. The wall thickness of the vacuum tank is uniform, so it can withstand high negative pressure above -0.096Mpa, and it will not deform after long-term high-pressure use.

3. The solid phase extraction instrument is uniformly pressurized everywhere, with good air tightness and strong stability.

4. The extraction speed is consistent, and the control and adjustment are convenient.

5. Multi-channel can be controlled independently, and the joint is corrosion-resistant.

6. The internal test tube rack of the solid phase extraction instrument is made of polytetrafluoroethylene, so it has high corrosion resistance.
