Borosilicate glass microfiber Filters 42.5mm 1.5µm BIOSupplyHouse

Description

Product Overview

Our Borosilicate glass microfiber disc filters are engineered for the most demanding laboratory filtration tasks. Constructed from high‑purity borosilicate glass, each 42.5 mm disc offers a nominal retention rating of 1.5 µm, delivering consistent and repeatable results for suspended‑solids analysis. The filters are pre‑washed, binder‑free, and feature a uniform 0.43 mm thickness with a basis weight of 64 g/m², ensuring minimal pressure drop while maintaining structural integrity. The product complies with SM 2540D and EPA 160.2 protocols, making it suitable for both research and compliance testing environments. Packaged in a tamper‑resistant sealed container, the 100‑filter bulk supply provides a cost‑effective solution for high‑throughput laboratories.

Usage

These disc filters excel in a variety of real‑world applications. In water quality labs, they are used to filter river, wastewater, and drinking water samples prior to gravimetric or spectrophotometric analysis. Their high temperature resistance up to 475 °C allows use in hot‑plate digestion and thermal extraction workflows where conventional polymer filters would melt or deform. The binder‑free construction eliminates the risk of leaching contaminants, making the filters ideal for trace‑metal and organic compound studies. Whether you are performing routine monitoring, method development, or validation studies, the 42.5 mm size fits standard filter holders and vacuum manifolds, providing seamless integration into existing protocols.

FAQ

What is the maximum temperature these filters can withstand?

The filters are rated for continuous operation up to 475 °C, making them suitable for high‑temperature digestion and thermal extraction applications.

Do the filters require any additional preparation before use?

No additional preparation is needed. They arrive pre‑washed, dried, and ready to install directly into compatible filter holders.

Are these filters compatible with standard vacuum filtration equipment?

Yes, the 42.5 mm diameter matches the most common laboratory filter holder sizes, allowing seamless integration with existing vacuum manifolds and filtration rigs.

How do these filters meet EPA Method 160.2 requirements?

The 1.5 µm nominal retention, combined with the binder‑free glass composition, ensures that the filters capture suspended solids without introducing extraneous material, satisfying the performance criteria outlined in EPA Method 160.2.

What is the benefit of purchasing a 100‑filter pack?

Buying in bulk reduces the cost per filter, guarantees a consistent supply for high‑throughput labs, and minimizes the risk of running out of critical consumables during important testing cycles.
