Spare Vacuum Base with Sintered Disc , 47mm | For 1000mL Filtration Assembly

The 47mm Vacuum Base with Sintered Disc is a critical component for precision vacuum filtration. This spare unit is specifically designed to fit standard 1000mL filtration assemblies, providing a stable and chemically inert support platform for membrane filters.

Key Features

• Integral Sintered Disc: The base features a fused-in G1 or G2 grade sintered glass disc that ensures even distribution of vacuum and provides excellent support for 47mm filter membranes.

• Borosilicate 3.3 Glass: Manufactured from high-expansion borosilicate glass to withstand thermal shock and resist aggressive solvents and acids.

• Precision Ground Joint: Features a standard taper joint (typically 40/35 or similar) to ensure a vacuum-tight fit with the receiving flask.

• Easy Maintenance: The glass disc is designed for easy cleaning and is fully autoclavable for sterile applications.

Usage Information

Essential for Modern Laboratory Applications

The 47mm Sintered Disc Base is a critical component in various scientific protocols, including:

1. HPLC Solvent Filtration: Removing particulates to protect sensitive columns and pumps.

2. Microbiological Analysis: Utilizing membrane filters to capture and culture bacteria.

3. Gravimetric Analysis: Providing a stable platform for precise solid-matter measurement.

For best practices on maintaining vacuum integrity and choosing the right membrane pore size, refer to the ASTM International standards for filtration.

Installation & Care Instructions

To extend the life of your Spare Vacuum Base:

• Inspection: Always check for hairline cracks or “stars” before applying vacuum pressure to ensure lab safety.

• Cleaning: Clean immediately after use. For stubborn residues, soak in a mild cleaning solution or ultrasonic bath. For more specialized cleaning tools, see our Laboratory Cleaning Supplies .

• Autoclaving: This borosilicate base is fully autoclavable; ensure it is cooled slowly to prevent thermal shock.
