GVS Filter Paper, Disk, 90mm, Low Ash-Very Slow, Grade 05, 100/PK FP090DXS05QALC01

Glass microfiber filter discs for laboratory and environmental sampling applications. Designed to retain particles at 1.6 µm, these 47 mm binder-free glass fiber discs provide fine retention with fast flow for water and air pollution monitoring, foodstuff analyses, protein filtration, and filtration of water, algae and bacteria cultures. The depth-structure large-surface-media offers high impurity retention capacity combined with low filter resistance and a high retention DOP of 99.998%.

Key Features:

• Diameter: 47 mm
• Filter media: Glass fiber (binder-free)
• Nominal retention / pore size: 1.6 µm
• Thickness: 260 µm
• Pack quantity: 100 discs per pack
• Retention DOP: 99.998%

Advantages:

• Fast flow performance for quicker filtrations while maintaining fine particle retention.
• High impurity-holding capacity and low filter resistance due to depth-structure glass microfiber media.
• Binder-free construction reduces extractables, making discs suitable for solvent filtration and gravimetric/analytical determinations.
• High retention DOP (99.998%) ensures reliable capture of target particulates for monitoring and analytical workflows.
