Cellulose Filter Paper, Folded, 185mm, Qualitative, Very Fast, 6-9um, Nonsterile, 100/Pk
GVS SKU: FP185DXF55CREC01

Featuring a crêped, very fast qualitative cellulose medium, these 185mm folded filter discs deliver rapid gravity and vacuum filtration for routine laboratory separations. The crêped surface increases the effective filtration area to improve flow rate and dirt-holding capacity, making the discs well suited to clarifying liquids and handling coarser precipitates. With a nominal particle retention of 6 to 9 microns, a thickness of 145 microns, and a basis weight of 65 g/m², each disc provides consistent, reproducible performance across general-purpose analytical and technical work. The hydrophilic cellulose structure wets readily with aqueous samples, and the low ash content of less than 0.1% keeps residue contribution minimal for qualitative identification tasks.

Key Cellulose Media Characteristics

• Hydrophilic cellulose construction wets quickly with aqueous solutions and common laboratory liquids.
• Crêped surface increases filtration area to improve flow rate and dirt-holding capacity.
• Very fast filtration speed for rapid separation of coarse particles and clarification of liquids.
• Nominal particle retention of 6 to 9 microns suits routine qualitative separations.
• Low ash content of less than 0.1% minimizes residue for qualitative identification work.

Key Construction Characteristics

• 185mm diameter discs supplied pre-folded for use in analytical funnels.
• Qualitative grade cellulose medium with a 145 micron thickness.
• Basis weight of 65 g/m² for consistent handling and flow.
• Nonsterile, packaged 100 discs per pack.

These folded discs maintain dependable, reproducible filtration across routine clarification and sample preparation tasks. The very fast crêped structure moves sample through quickly while capturing coarse particulate, helping protect downstream steps and preserve sample integrity. Consistent thickness and basis weight support uniform performance from disc to disc.
