Glass Solvent Filter Application and Installation

Glass solvent filter is a filtration apparatus for micro-filtration, separation of liquid and particles. It is made of borosilicate glass and can be autoclaved at 121℃, the full set include:

1. 300ml glass funnel.
2. 1000ml glass collection bottle.
3. Anodized aluminum spring clamp.
4. Support frit and base.

Installation of Glass Solvent Filters

  1. Choose the Right Filter:
    • Select a glass solvent filter with the appropriate pore size based on the type and size of particles you want to remove. Consider the solvent compatibility of the filter material.
  2. Inspect the Filter Housing:
    • Before installation, inspect the glass solvent filter housing for any damage. Ensure that all parts, including seals and o-rings, are in good condition.
  3. Prepare the Filter Assembly:
    • Assemble the glass solvent filter according to the manufacturer’s instructions. This typically involves placing the filter in the housing, ensuring proper alignment, and securing any additional components.
  4. Flush the System:
    • Before connecting the filter to the solvent source, flush the filter and the connecting lines with a small amount of solvent to remove any loose particles and prepare the system for use.
  5. Connect the Inlet and Outlet:
    • Connect the glass solvent filter to the solvent source using appropriate tubing. Ensure that the inlet and outlet connections are secure and leak-free.
  6. Bleed Air from the System:
    • If there is air in the system, bleed it out by opening the system briefly to allow solvent to flow through. This ensures proper flow and prevents air bubbles from interfering with the filtration process.
  7. Initiate Filtration:
    • Start the solvent filtration process according to the desired flow rate. Adjust the system parameters as needed for the specific application.
  8. Monitor Performance:
    • Monitor the performance of the glass solvent filter during use. Check for any signs of clogging, pressure changes, or other irregularities that may indicate the need for maintenance or replacement.
  9. Replace as Needed:
    • Glass solvent filters have a finite lifespan and should be replaced periodically based on usage and the manufacturer’s recommendations. Regularly replace filters to maintain optimal filtration efficiency.

Application of Glass Solvent Filters

  1. Solvent Purification:
    • Glass solvent filters are commonly used to purify solvents before they are used in analytical techniques such as High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), or other sensitive laboratory procedures.
  2. Particle Removal:
    • These filters are effective in removing particles, debris, and impurities from solvents, preventing potential damage to equipment or interference with analytical results.
  3. Protecting Instruments:
    • Solvent filters serve as a protective barrier for sensitive laboratory instruments. By ensuring that solvents are free from contaminants, they help extend the life and performance of equipment.
  4. Enhancing Column Life:
    • In chromatography applications, using filtered solvents helps to prevent the introduction of particulates into columns, thereby extending the life and efficiency of chromatographic columns

Always follow the manufacturer’s guidelines and instructions for the specific glass solvent filter model you are using. Additionally, adhere to laboratory safety protocols and practices when working with solvents and filtration systems.

It is always suggested using together with a vacuum pump for better filtration efficiency, and micro-porous membrane filter also used when filtration.

The filter used for filtration of micro-particles and bacteria. 0.22 and 0.45-micron membrane filter suggested mostly. The glass solvent filter is suitable for liquid chromatography, ion chromatography, chemical analysis, sanitary inspection, environmental monitoring, biological products, product industry, scientific research, etc.

Advantage of the borosilicate glass made glass solvent filter is high filtration precision, low absorption, no interference, no leakage and anti-corrosion (acid and base) and with fast filtration efficiency.
