Solvent Filtration Apparatus Details
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
-
Step 1Firstly, 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.
-
Step 2Place 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.
-
Step 3Connect 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.
-
Step 4When 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 filtering aqueous, organic, and corrosive liquids. It is highly recommended for HPLC mobile phase filtration to ensure purity and prevent blockages. It is also suitable for sterile testing and sterilizing heat-sensitive substances.
What material is the filter apparatus made of?
The apparatus is made of high-quality Boro 3.3 high borosilicate glass, which is smooth, bubble-free, highly corrosion-resistant, and has an annealing point of up to 500°C. The fixing clamp is made of high-toughness circular aluminum alloy.
How do I prevent liquid leakage during the filtration process?
To prevent leakage, ensure the glass grinding ports are properly aligned, verify that the filter membrane lies completely flat on the sand core, and check that the aluminum alloy clamp is securely and uniformly tightened.
What should I do if the filtration speed slows down?
A slow filtration rate usually indicates that the filter membrane has accumulated too many impurities. Check the membrane and replace it with a new one if necessary to restore optimal filtration speed.
How do I protect my vacuum pump from damage during use?
Avoid overfilling the suction triangle bottle, and prevent it from tilting or shaking. This prevents the filtered liquid from being drawn into the vacuum hose, which can damage the pump core.
