Description
Product Overview
The Whatman 1001-125 filter paper circles are engineered to meet the rigorous demands of modern laboratory environments where precision, consistency, and reliability are paramount. Constructed from high‑quality cellulose fibers, each circle provides a uniform 11 micron pore size that falls within Grade 1 specifications, ensuring that particulate matter is effectively retained while allowing clear liquids to pass through with minimal resistance. The 125 mm diameter offers a generous surface area, facilitating rapid filtration rates of 10.5 s per 100 mL per square inch, which translates to efficient workflow and reduced processing times for routine analytical procedures. These circles are supplied in a convenient pack of 100, making them an economical choice for laboratories that require a steady supply of dependable filter media. The product is certified by Whatman, a trusted name in filtration technology, and has been a staple in scientific research since its introduction in 2006. Its versatility extends across multiple sectors, including food safety testing, agricultural product analysis, air pollution monitoring, and educational settings where students learn fundamental qualitative separation techniques.

Usage
Designed for a broad spectrum of applications, the Whatman 1001-125 filter paper circles excel in scenarios that demand high clarity and reproducibility. In the food industry, they are employed to remove suspended solids from beverages, dairy products, and liquid extracts, ensuring that final products meet stringent quality standards. Agricultural laboratories use these circles to filter soil leachates and plant extracts, enabling accurate determination of nutrient content and contaminant levels. Environmental monitoring professionals rely on the consistent pore size to capture airborne particulates and waterborne pollutants, supporting regulatory compliance and research initiatives. In academic laboratories, the circles serve as an ideal teaching tool for demonstrating qualitative analytical separations, allowing students to observe the principles of filtration in real time. Their robust construction tolerates a range of chemical exposures, making them suitable for both aqueous and mildly acidic or basic solutions. The ease of handling, combined with the standardized dimensions, simplifies setup and reduces the potential for user error, thereby enhancing overall experimental reliability.

FAQ
What types of liquids can be filtered with the 1001-125 circles?
The circles are suitable for a wide range of liquids, including aqueous solutions, mild acids and bases, food extracts, agricultural samples, and environmental water samples. Their chemical resistance makes them adaptable to most routine laboratory filtrations.
How does the 11 micron pore size affect filtration performance?
An 11 micron pore size offers a balance between speed and retention, allowing liquids to pass quickly while effectively capturing suspended particles larger than 11 µm. This results in clear filtrates without the need for multiple filtration stages.
Can the filter paper be used for quantitative analysis?
While the 1001-125 circles are classified as qualitative filter paper, they provide consistent performance that can support semi‑quantitative assessments where particle size exclusion is a key factor. For fully quantitative methods, a filter with a tighter specification may be recommended.
Is there a recommended storage condition to maintain filter integrity?
Store the filter circles in a cool, dry environment away from direct sunlight and excessive humidity. Keeping them in their original packaging until use helps preserve their pore structure and prevents contamination.
What support is available if I encounter an issue with the product?
