Superior Grade Filters for a Variety of
Biological and Environmental Methods
- Type A/E meets the requirements for suspended solids testing, as described in Standard Methods for the Examination of Water and Wastewater, current edition.
- 在过滤难以过滤或高度污染的溶液时，可以减少过滤成本和过早堵塞。
- 通过高容量预过滤器，延长过滤器寿命、减少最终过滤器更换频率。
- 消除样品污染。无粘合剂硼硅酸盐玻璃纤维无附加析出物。
- 利用一系列可选过滤器厚度，过滤各类颗粒负载和粘稠溶液。
- Filters with binder offer excellent wet strength for easy handling and filter integrity.
A/E 型玻璃纤维
- For testing dissolved and suspended solids in wastewater and gravimetric analysis of air pollutants.
- High flow rates, wet strength, and dirt (solids) holding capacities.
Type A/B Glass Fiber
- High dirt-loading capacity with 2.5 times thicker glass than Type A/C.
- Manufactured of the highest quality borosilicate glass microfibers.
Type A/C Glass Fiber
- For testing dissolved and suspended solids in wastewater.
- Useful for cell harvesting applications.
- Purity eliminates risk of unwanted contaminants leaching into the filtrate.
Type A/D Glass Fiber
- Excellent prefilters for solutions with a heavy load of large-sized particulate that must be removed.
- Large nominal pore size reduces membrane clogging.
Extra Thick Glass Fiber With Binder
- Preferred for prefiltration of viscous biological solutions.
- High particulate-holding capacity makes discs efficient depth filters and allows for filtration of large volumes of solutions.
Metrigard™ Glass Fiber With Binder
- Useful for prolonging membrane filter life in liquid systems that contain substantial amounts of particulate matter.
TCLP Glass Fiber
- Designed to meet requirements for use in U.S. EPA SW-846 Method 1311:Toxic Characteristics Leaching Procedure (TCLP).
