Featuring a binder-free borosilicate glass microfiber depth medium, these 150mm filter discs deliver 1.5um nominal particle retention for demanding gravimetric and clarification work. The hydrophilic, slow-flow construction provides a large internal surface area that captures fine particulates throughout the depth of the medium rather than only at the surface, supporting high dirt-holding capacity and reliable throughput on heavily loaded aqueous samples.
Key Glass Fiber Media Characteristics
- Nominal retention: retains particles down to a 1.5um nominal rating, making it well suited to demanding particulate work rather than absolute sterilizing-grade filtration.
- Hydrophilic depth structure: wets readily with aqueous samples and traps particulates throughout the medium for high particulate loading.
- Binder-free borosilicate: 100 percent borosilicate glass microfiber with no binder, minimizing extractables for solvent filtration and gravimetric analysis.
- High loading capacity: the open depth matrix sustains throughput on heavily loaded samples and serves effectively as a prefilter to protect downstream membranes.
- Slow flow speed: the tighter 1.5um grade favors finer particulate capture and clarity.
Key Construction Characteristics
- Format: 150mm diameter filter disc.
- Grade: DFAAH glass microfiber.
- Sterility: supplied nonsterile.
- Packaging: 100 discs per pack.
These discs maintain consistent retention and flow across the medium for repeatable results in suspended solids and gravimetric procedures. The pure borosilicate composition preserves sample integrity by limiting media migration and extractables, helping deliver clean filtrate and dependable performance run after run.
