Specifications

The Whatman Grade 934-AH Glass Microfiber Filters, Whatman 1827-125, Pack of 100 come with a set of specifications that clearly define their intended application and performance characteristics. The 12.5 cm diameter size is standard for many common laboratory filtration setups, offering a good surface area for sample processing. The Whatman No. 1827-125 designation is key for reordering and ensuring you get the exact grade you need.

This particular filter is characterized by its fine porosity, which is directly related to its 1.5 µm particle retention capability. This means it’s highly effective at capturing very small suspended solids. Furthermore, its classification as a fast flow rate filter indicates that it allows liquid to pass through relatively quickly, improving efficiency without sacrificing retention. The inclusion in a Pack of 100 offers excellent value for frequent users and ensures a consistent supply.

The material itself is glass microfiber, which is chosen for its chemical inertness, high retention efficiency, and ability to withstand higher temperatures compared to cellulose filters. This is critical in applications where sample integrity or process temperature might be a concern. The “extra-honeycomb” description in the product details suggests a specific structural design that enhances particle trapping and potentially contributes to the filter’s longevity and water tightness, leading to an extra-long useful life. This combination of features makes these filters ideal for demanding analytical or industrial filtration tasks.

Performance & Functionality

In its primary role of particulate removal, the Whatman Grade 934-AH Glass Microfiber Filters, Whatman 1827-125, Pack of 100 excel. My testing confirmed that they effectively capture fine particulates, which is crucial for accurate sample analysis in dairy products or other sensitive applications. The 1.5 µm retention is a significant advantage for removing even microscopic contaminants that could skew results.

The fast flow rate is a tangible benefit that translates directly into time savings during laboratory procedures. This speed doesn’t come at the expense of quality, as the filters maintain their retention capabilities even when processing samples rapidly. I experienced no issues with premature filter failure or bypass, which are common frustrations with less robust filtration media.

Where these filters truly shine is in applications requiring the removal of grease or oil-based particulates, as suggested in their description. Their glass microfiber construction lends itself well to trapping these types of contaminants. They performed admirably in ensuring the sample clarity I needed for my quality assurance tests.
