Filter Holder for Glass with Silicon Stopper 47mm (BOROSIL®)

The “Filter Holder for Glass with Silicon Stopper 47mm (BOROSIL®)” is a specific piece of laboratory equipment designed for vacuum filtration processes using filter paper or membranes with a diameter of 47mm. Here’s a breakdown of its features and usage:

1. Filter Holder Components:
   • Glass Funnel: The filter holder includes a glass funnel with a diameter of 47mm. This funnel is where the filter paper or membrane is placed to trap solid particles while allowing liquids to pass through.
   • Silicone Stopper: The silicone stopper is used to secure the glass funnel to the neck of a filtration flask or bottle. It forms a tight seal to prevent leakage during vacuum filtration.
   • Connection: The filter holder is designed to fit securely onto the neck of a compatible filtration flask or bottle, allowing for a seamless connection between the funnel and the vessel.
2. Usage:
   • Place the glass funnel with the filter paper or membrane into the filter holder.
   • Insert the silicone stopper into the neck of a filtration flask or bottle.
   • Securely attach the filter holder to the neck of the flask or bottle using the silicone stopper.
   • Connect the filtration setup to a vacuum source using vacuum tubing.
   • Apply vacuum pressure to the filtration setup, which draws the liquid through the filter medium, trapping solid particles while allowing the liquid to pass through into the flask or bottle.
   • Collect the filtered liquid in the flask or bottle for further processing or analysis.
3. BOROSIL®: BOROSIL® is a renowned brand known for manufacturing high-quality laboratory glassware made of borosilicate glass. Borosilicate glass offers excellent resistance to chemical corrosion, thermal shock, and mechanical stress, making it ideal for use in laboratory applications, including filtration.

Overall, the Filter Holder for Glass with Silicone Stopper 47mm (BOROSIL®) provides a reliable and efficient solution for vacuum filtration processes, ensuring accurate separation of solids from liquids in laboratory settings. It is designed to securely hold the glass funnel in place while creating a tight seal to prevent leaks during filtration.
