Glass Micro Fibre Filter Circles GF121 47mm 100/Pk

Glass Micro Fibre Filter Circles (GF121/GF/A, 47mm, 100/Pk) are high-efficiency, binder-free borosilicate glass filters with 1.6µm retention and fast flow rates.

They are primarily used for environmental analysis (water/wastewater, air pollution monitoring), gravimetric analysis, algae/bacteria culture filtration, and protein analysis.

Key Uses and Applications: Environmental Monitoring: Essential for testing total suspended solids (TSS) in water and wastewater.

Air Sampling: Used for gravimetric determination of air particulates, stack sampling, and air pollution monitoring.
Laboratory Filtration: General-purpose, fast-flow filtration of fine particles.
Life Sciences: Suitable for filtering algae/bacteria cultures and protein filtration.
Chemical Analysis: Foodstuff analysis and radioimmunoassay of weak \(\beta \) emitters. 
Product Specifications: Material: Binder-free Borosilicate Glass Microfibre.Retention: 1.6 \(\mu m\) (nominal).
Size: 47 mm diameter.Thickness: Approx. 260 \(\mu m\).
Quantity: 100 circles per pack. 
These filters offer high loading capacity and can withstand high temperatures.

Biological and Chemical Research
Biochemical Cultures: Used in the filtration of algae and bacteria cultures.
Biomolecule Purification: Applied in protein filtration and radioimmunoassay of weak beta emitters.
LSC Techniques: Often used in Liquid Scintillation Counting (LSC) techniques that require high loading capacity.

Industrial and General Lab Use
Foodstuff Analysis: Utilized for food quality testing and monitoring.
Membrane Prefiltration: Serves as a prefilter to protect more expensive or sensitive membranes, extending their usable life.
High-Temperature Stability: Capable of withstanding temperatures up to 500°C, making them suitable for processes involving hot fumes or ignition.

Product Specifications (GF121 47mm)
Material: Pure borosilicate glass fiber without binders.
Diameter: 47 mm.
Retention: Equivalent to Grade GF/B, providing finer particle retention than standard grades like GF/A (approx. 1.0 µm to 1.6 µm depending on specific manufacturer standards).
