Description
The major use of the glass microfiber filter disc is as a depth prefilter in clarification and sterile filtration. As a prefilter, it is placed directly on top of a membrane filter. The prefilter diameter must be the one specified for the chosen holder; larger diameters will intrude under the sealing ring of the holder and cause leakage.- Manufactured with a hydrophillic acrylic binder for defined strength
- Has a high particle loading capacity for filtering relatively dirty liquids
- Mechanically and chemically stable, with a temperature resistance up to 220°C
- Other filter characteristics:
- Weight: 73g/m2
- Extractable content in isopropanol: 1.54%
- Extractable content in water: 1.12%
- Pressure drop at 5.3cm/sec: 0.363kPa
- Total throughput at 1bar: 320mL/min./cm2
