Glass Solvent Filter


A glass solvent filter is an essential laboratory apparatus designed for the purification of solvents and other liquids by removing impurities and particulates. Constructed primarily from high-quality borosilicate glass, these filters ensure chemical durability and resistance to thermal shock, making them suitable for various laboratory applications.​

Key Components:

  • Funnel: Typically available in capacities ranging from 300 mL to 1000 mL, the funnel holds the liquid to be filtered.​

  • Filter Support (Frit): A sintered glass disc, often with a porosity of 10–15 µm (medium grade), facilitates the filtration process by trapping particulates while allowing the solvent to pass through.

  • Receiver Flask: Collects the filtered solvent. Common volumes include 500 mL, 1000 mL, and 2000 mL.​

  • Clamp and Adaptor: Securely connects the funnel to the receiver flask, ensuring a leak-proof seal.​

Compare

Glass solvent filters are devices used in laboratories to filter solvents and other liquids to remove impurities and particles and ensure the accuracy and cleanliness of chemical experiments and analyses. It typically consists of a funnel section, filter media, support base, and clamp, and is designed to facilitate the rapid and efficient filtration of large volumes of solvent while maintaining a good seal to prevent contamination. We can also provide filter membranes of various materials(Nylon, PTFE, PVDF, PES ), pore sizes(0.22μm, 0.45μm) and diameters(13mm, 25mm, 47mm, 50mm, 90mm). Welcome to discuss.

 

Application

◆ Solvent Purification

In chemical synthesis and preparation, solvents need to be pure to avoid the introduction of unnecessary impurities. Glass solvent filters are used to remove particles and other impurities from solvents.

◆ Sample Preparation

In analytical chemistry, such as chromatography and spectroscopy, samples need to be clean and particle-free. Use glass solvent filters to ensure sample purity.

◆ Biological and Biochemical Experiments

When working with sensitive biological samples, such as cell culture media, sterile and particle-free solvents and buffers are required. Glass solvent filters can be used in such applications, especially those equipped with sterile filtration media.

◆ Laboratory Safety

Glass Solvent Filter Uses filters can reduce harmful particles and aerosols that may be generated during experiments and improve the safety of laboratory work.

 

Features
▶ Solvent Filter is widely used almost able to meet almost all the filtration needs of the laboratory.
▶ Large effective filtration area, save the cost of filter film use, and improve the filtration rate.
▶ Good pressure resistance, which can be used for high temperature and high pressure.
