Description
Product Overview
The Whatman 1827‑055 glass microfiber filter is engineered for precision laboratory filtration where reliability and performance are paramount. Constructed from high‑purity borosilicate glass microfibres, the filter offers a smooth, uniform surface that captures particles down to 1.5 µm while maintaining a robust 5.5 cm diameter. This geometry provides a high loading capacity, allowing large volumes of liquid to be processed before the filter reaches its breakthrough point. The filter’s binder‑free design eliminates the risk of leaching, ensuring that downstream analytical results remain uncontaminated. Flow rates of 3.7 seconds per 100 mL are achieved without sacrificing retention efficiency, a balance that is essential for applications such as total suspended solids (TSS) determination, turbidity removal, and bacterial culture filtration. The product complies with Standard Methods 2540D, reinforcing its suitability for regulatory‑compliant water quality testing. With a temperature tolerance exceeding 500 °C, the filter can be employed in high‑temperature protocols, including certain sterilization and ashing procedures, without degradation of its structural integrity.

Usage
Designed for a broad spectrum of laboratory environments, the Whatman 1827‑055 filter excels in water pollution monitoring, where accurate quantification of suspended solids is critical for environmental compliance. Researchers conducting cell harvesting benefit from the filter’s fine retention capability, which efficiently separates cellular material from culture media while preserving cell viability for downstream processing. In liquid scintillation counting, the filter removes particulate interference, enhancing the clarity of the scintillation cocktail and improving counting efficiency. Air pollution monitoring laboratories also employ the filter to capture aerosolized particulates from air sampling devices, enabling precise mass‑based analysis of airborne contaminants. The filter’s chemical resistance allows it to handle a variety of solvents and reagents, making it compatible with diverse analytical protocols ranging from acidic digestions to organic extractions. Its ease of use—simply insert the filter into a standard filtration apparatus—reduces setup time and minimizes handling errors, contributing to reproducible results across multiple runs.

FAQ
What is the maximum sample volume that can be filtered before the filter clogs?
The filter’s high loading capacity typically allows filtration of up to 500 mL of water with a turbidity of 10 NTU before breakthrough occurs. For samples with higher particulate loads, it is advisable to monitor flow rate and replace the filter when a noticeable pressure increase is observed.
Can the filter be used with organic solvents?
Yes, the borosilicate glass microfibres are chemically resistant to a wide range of organic solvents, including methanol, ethanol, and acetone. However, for aggressive solvents such as chloroform or dimethyl sulfoxide, a short pre‑wetting step is recommended to ensure optimal wetting and prevent air bubble formation.
Is the filter compatible with standard vacuum filtration apparatus?
Absolutely. The 5.5 cm diameter matches the standard filter holder size used in most laboratory vacuum filtration setups, allowing seamless integration without the need for adapters or modifications.
How should the filter be stored to maintain its performance?
Store the filters in a clean, dry environment, preferably in their original sealed packaging. Avoid exposure to extreme humidity or direct sunlight, which could affect the glass fibre structure over prolonged periods.
What warranty or guarantee does Whatman provide for this filter?
Whatman offers a one‑year limited warranty covering manufacturing defects. If a filter fails to meet the specified performance criteria within this period, customers can contact technical support for a replacement or refund, subject to verification of the issue.
