Description

[table id=520 /]

MEDILAB Sintered Discs are precision-manufactured filtration components made from high-grade Borosilicate Glass 3.3. Designed for integration into laboratory glassware, these discs provide controlled filtration, particle retention, and efficient separation of liquids and solids. Their consistent porosity and chemical inertia make them essential for research laboratories, QC/QA environments, pharmaceutical operations, and industrial filtration systems that demand accuracy and reliability.

Key Features

• High-precision porosity (Grades 0–5 available on request) for reliable and repeatable filtration performance.
• Excellent chemical and thermal resistance—suitable for acids, alkalis, solvents, and temperature variations.
• Durable sintered construction ensures long service life and maintains pore integrity under routine lab use.
• Uniform particle retention thanks to consistent pore distribution.
• Autoclavable and reusable, enabling long-term, cost-efficient operation.
• Compatible with most laboratory glassware assemblies, including filtration setups, Gooch crucibles, and custom apparatus.
• Non-reactive and contamination-free, supporting high-purity analytical work.
