Solvent Filtration Apparatus Specifications & Operation
Product Name: Boro 3.3 Glass Beaker
Product Specifications: 250ml-5000ml
Product Material: High borosilicate glass
Product Introduction:
Mainly used for the filtration of aqueous, organic, and corrosive liquids, for the analysis of specific pollutants, particularly recommended for the filtration of HPLC mobile phases, with a certain degree of gas permeation to ensure the purity of the mobile phase and prevent blockage of the HPLC liquid path. It can also be used for sterile testing, culture sterilization filtration, and sterilization filtration of heat sensitive substances.
This filter is made of high-quality silicon glass, which is smooth and transparent, free of impurities and bubbles, corrosion-resistant, and has an annealing point of up to 500°C.
Its fixing device is a circular aluminum alloy clamp with high toughness, which can reliably resist distortion and deformation even after long-term use. The unique circular design allows for a tight fit between the center and the joint, ensuring high stability and preventing liquid leakage.
Operation method:
1
Firstly, insert the straight tube filter element into the mouth of the suction triangle bottle, gently downward and slightly rotate it to make it fit tightly.
2
Place the filter membrane in the middle of the sand core of the filter element, place the filter cup flat on the filter head, grind the flat surface to match, and clamp it with a clamp.
3
Connect the negative pressure nozzle of the Vacuum pump to the rubber hose, and connect the other end to the rubber hose connection nozzle of the suction triangle bottle.
4
When filtering, inject the solution into the filter cup, turn on the vacuum pump, and under vacuum, the solution flows through the filter membrane on the filter head into the suction triangle bottle for filtration.

Precautions
1. Choose the appropriate filter membrane according to the different filtration solutions.
2. First, turn on the vacuum pump, and then pour the solvent to be filtered into the filter cup for filtration.
3. During the filtering operation, do not make the liquid filtered in the triangular bottle too full, tilted, or fluctuating to prevent solvent from being drawn into the pump through the vacuum hose and damaging the pump core.
4. If there is leakage between the filter head and filter cup, check whether the grinding port is aligned, whether the filter membrane is flat, and whether the tightness of the clamp is uniform and reliable.
5. Slow down the filtration speed of the same solvent. Check if the filter membrane accumulates too many impurities that affect the filtration speed. If necessary, replace the filter membrane.
6. The solvent filter is a fragile item and should not be moved as a whole or with a clamp.
Frequently Asked Questions (FAQ)
What are the primary applications of the Solvent Filtration Apparatus?
It is mainly used for the filtration of aqueous, organic, and corrosive liquids, analysis of specific pollutants, and filtration of HPLC mobile phases. It ensures mobile phase purity, prevents HPLC liquid path blockages, and can also be used for sterile testing and culture sterilization filtration.
What materials are used in the construction of this apparatus?
The filter is made of high-quality Boro 3.3 borosilicate glass, which is smooth, transparent, free of impurities, corrosion-resistant, and has an annealing point of up to 500°C. The fixing device is a high-toughness circular aluminum alloy clamp.
How do I choose the correct filter membrane?
You should select the appropriate filter membrane based on the specific chemical properties of the filtration solutions being used.
How can I prevent solvent from damaging the vacuum pump during operation?
During filtration, do not allow the liquid in the suction triangular bottle to become too full, tilted, or to fluctuate. This prevents the solvent from being drawn into the pump through the vacuum hose and damaging the pump core.
What should I check if there is a liquid leak during the filtration process?
If a leak occurs between the filter head and the filter cup, check whether the grinding port is properly aligned, ensure the filter membrane is flat, and verify that the clamp tightness is uniform and reliable.
What should I do if the filtration speed slows down?
If the filtration speed decreases for the same solvent, check if the filter membrane has accumulated too many impurities. If necessary, replace the filter membrane to restore optimal speed.
