Product Description
The Whatman Polydisc Filter GW | 10463400 is a high-performance in-line groundwater filtration device specifically engineered for the preparation of groundwater samples for dissolved heavy metal analysis. Designed to meet the requirements of environmental laboratories, this filter features a 0.45 µm nylon membrane combined with a 100% quartz fiber prefilter, ensuring efficient removal of suspended particles while maintaining exceptionally low background levels of trace metals. Each production batch is certified for trace element analysis, making it ideal for regulatory environmental testing.
The Polydisc GW incorporates a durable polypropylene housing with a large 20.4 cm² filtration area, allowing high sample throughput and excellent dirt-loading capacity even when filtering heavily contaminated groundwater samples. The integrated quartz fiber prefilter protects the nylon membrane from premature clogging, enabling faster filtration and improved operational efficiency. The device is compatible with 6–14 mm internal diameter tubing, making it suitable for field sampling as well as laboratory filtration systems.
The 10463400 model features a 50 mm diameter, 0.45 µm pore size, and is supplied as a non-sterile pack of 20. It is widely used in environmental monitoring laboratories, groundwater assessment projects, water treatment facilities, geological surveys, and research institutions performing trace metal analysis according to environmental standards such as US EPA Method 3005A. Its robust construction, low extractable content, and certified performance make it a trusted solution for groundwater sample preparation.
