Description générale
The 934-AH RTU contains the trusted binder-free, high purity borosilicate glass microfiber filter mentioned in Standard Methods 2540D. It comes pre-washed and pre-weighed, this eliminates filter pre-treating and streamlines your laboratory process. Each RTU filter is packaged within an aluminium pan with the filter weight clearly printed on a heat resistant label.
The fine particle retention of this popular grade is superior for its high retention efficiency at high flow rates and its high loading capacity. This is a smooth surface, high-retention borosilicate glass microfiber filter which withstands temperatures over 500°C.
Used for determining total suspended solids in water, removal of turbidity, and filtration of bacterial cultures. Grade 934-AH is used for a wide range of laboratory applications. It is recommended for water pollution monitoring, cell harvesting, liquid scintillation counting, and air pollution monitoring.
Features and benefits:
- Fast and convenient: use the pre-washed, pre-weighed filter immediately, no need to pre-treat
- Excellent fine particle retention: allows high particle retention efficiency when filtering large volumes
- Binder-free, high-grade borosilicate glass microfiber: enables use with temperatures up to 550ºC
- Available in a wide range of sizes: in circle and sheet formats
- High loading capacity: capable of processing very turbid streams
- Low fiber shedding: improves quality assurance of test results
Applications:
- Determination of total solids in water
- Water pollution monitoring
- Air pollution monitoring
- Cell harvesting
- Liquid scintillation counting
