The laboratory corrosion-resistant vacuum filtration device is a professional model with different special suction filtration products and strong special purpose. There are many kinds of requirements for laboratory filtration, such as medium sterilization filtration, buffer removal of impurities, suspended solids and microscopic inspection and filtration, etc. These filters are generally not highly corrosive, and Electroplating solution filtration, mobile phase solvent purification and filtration, etc. all have certain or strong corrosiveness. If ordinary models are used, volatile gases are very easy to corrode the inlet and outlet valve sheets and other parts inside the vacuum pump, so that vacuum will gradually appear. Insufficient degree, abnormal machine noise, can not pump at all, until the machine starts to have no reaction.
For the filtration of corrosive samples, it is necessary to use CH300A anti-strong chemical corrosion filtering device such as St. Stephen's. The most notable feature of this model is the parts of the suction pump and the gas contact, including the joint, the pump body, The internal cavity, the inlet and outlet gas, the diaphragm and the like are all made of polytetrafluoroethylene (PTFE) material, which has excellent chemical corrosion resistance. The PTFE material will not be corroded in the case of perennial use, so this material is widely used in strong chemical corrosion applications in various industries.
The anti-strong chemical corrosion filter unit CH300A also has the following features:
1.CH300A corrosion-resistant vacuum filter unit is equipped with advanced diaphragm vacuum pump. The pump body includes pump tube interface, pump head, internal gas line, valve plate and diaphragm. All parts are made of PTFE with excellent chemical resistance. Made of ethylene (PTFE, commonly known as Teflon). With a 2-year free warranty and excellent quality, users no longer have to worry about corrosion damage after long-term use.
2. The filter bottle set is made of high quality borosilicate glass material. The sand core is made with excellent craftsmanship and good uniformity. When filtering, the filtration speed is significantly improved compared with traditional products.
3. The fixture for fixing the filter bowl and the sand core filter base is made of aluminum alloy and is anodized to have certain corrosion resistance.
4. Pay attention to detail design with tick marks for easy observation of liquid level.
5. Water-proof protector with anti-back suction can 100% avoid the filtrate directly into the pump, which is safer.
6. Optional corrosion-resistant vacuum control valve (Cat. No.: CH-VR) for easy observation of vacuum and adjustment of vacuum and filtration rate as needed.
