For precise and reliable water analysis, the Hach® QT Filters are the ideal choice for environmental testing and laboratory applications. With a pleated design that enhances flow rates by effectively doubling the filtration area, these filters ensure optimal performance in gravimetric procedures when used with Büchner funnels and high vacuum setups. Featuring a pore size of 3 - 5 µm and a generous diameter of 185 mm, each quantitative filter is engineered for maximum abrasion resistance thanks to its optimized ashless hardened circles. Suitable for a variety of methods outlined in the Hach Water Analysis Handbook, these filters are a trusted solution for your critical wet chemistry needs, providing the accuracy and reliability required for thorough analysis.
