Whatman 1827-082 Glass Microfiber Binder Free Filter, 1.5 Micron,

Description

Product Overview

The Whatman 1827 082 glass microfiber filter is engineered for demanding laboratory environments where precision, speed, and durability are essential. Constructed from high‑purity borosilicate glass microfibres, the filter provides a smooth, binder‑free surface that captures particles down to 1.5 µm with exceptional efficiency. Its 8.2 cm diameter and Grade 934‑AH composition deliver a flow rate of 3.7 seconds per 100 mL, allowing rapid processing of large sample volumes without sacrificing retention quality. The filter’s robust glass matrix endures temperatures exceeding 500 °C, making it suitable for high‑temperature applications and repeated autoclaving. Certified to Standard Methods 2540D, it meets stringent criteria for total suspended solids analysis, turbidity removal, and bacterial culture filtration. The pack of 100 units ensures consistent performance across multiple experiments, reducing variability and supporting reproducible results.

Usage

Designed for a broad spectrum of laboratory tasks, this filter excels in water pollution monitoring, where accurate detection of suspended solids is critical for environmental compliance. Researchers harvesting cells for downstream analysis benefit from the filter’s high loading capacity, which captures dense cell suspensions while maintaining gentle flow to preserve cell integrity. In liquid scintillation counting, the filter removes particulate interference, enhancing counting efficiency and reducing background noise. Air pollution monitoring labs also employ the filter to trap aerosolized contaminants before analysis. Its temperature resistance enables use in protocols requiring heat treatment, such as sterilization steps or high‑temperature extractions. The filter’s compatibility with standard laboratory filtration apparatus ensures seamless integration into existing workflows, minimizing the need for additional equipment.

FAQ

What types of samples can I filter with the 1827‑082?

The filter is suitable for aqueous solutions, cell suspensions, liquid scintillation cocktails, and aerosol samples collected for air quality analysis. Its high loading capacity and temperature tolerance make it versatile for both low‑temperature and high‑temperature applications.

Can the filter be reused after cleaning?

While the filter is designed for single‑use to guarantee maximum retention performance, it can be cleaned and re‑sterilized for non‑critical applications. However, reuse may reduce its retention efficiency, so for quantitative analyses a fresh filter is recommended.

Is the filter compatible with standard vacuum filtration apparatus?

Yes, the 8.2 cm diameter matches common laboratory filter holders and vacuum manifolds. It fits seamlessly into standard glass or plastic filtration setups, eliminating the need for adapter equipment.

How does the filter perform in high‑temperature sterilization?

The borosilicate glass microfibre construction withstands temperatures above 500 °C, allowing autoclaving at typical sterilization conditions (121 °C, 15 psi) without degradation of the filter matrix or loss of retention capability.

What quality certifications does the filter have?

The product complies with Standard Methods 2540D for total suspended solids determination and meets ISO‑9001 quality management standards. Each batch is tested for flow rate, particle retention, and thermal stability to ensure consistent performance.
