Quantitative Filter Paper Discs, Ashless, 14-17um Retention, 110mm, Medium Speed, 100/Pk
GVS SKU: FP110DME43QANC01

Featuring an ashless cellulose depth medium made from refined pulp and pure cotton linters with a virtually 100% alpha-cellulose content, these 110mm quantitative filter paper discs deliver an even balance of medium retention and medium flow rate. The Grade DME43 medium has a nominal particle retention range of 14 to 17 microns and a thickness of 180 microns, with an ash content of less than 0.007% so no measurable contaminants are introduced during filtration. Each box contains 100 discs.

Key Cellulose Media Characteristics

• Ashless construction with less than 0.007% ash content for accurate gravimetric and inorganic analysis
• Nominal particle retention of 14 to 17 microns with medium filtration speed
• Manufactured from refined pulp and pure cotton linters at virtually 100% alpha-cellulose content for high purity
• 180 micron thickness providing dependable wet strength for routine and pressure filtration
• Suitable for Buchner funnel use and filtration under pressure

Key Construction Characteristics

• 110mm diameter circular disc format
• Hydrophilic cellulose medium for fast, even sample wetting
• Nonsterile, supplied 100 discs per box
• Comparable to Grade 43 quantitative ashless filter paper

This medium-speed quantitative grade maintains consistent retention across routine and demanding separations, supporting reliable, reproducible results. Its low ash content and high-purity cellulose structure help preserve sample integrity for gravimetric determinations and downstream instrumental analysis.

• Gravimetric Analysis The less than 0.007% ash content supports precise gravimetric determinations where filter residue must not contribute measurable weight.
• Soil Analysis Medium retention and flow make these discs well suited to separating solids from aqueous soil extracts.
• Air Pollution Monitoring The medium retains particulate collected for subsequent analysis, including XRF techniques.
• Foodstuffs Analysis The ashless cellulose medium clarifies and separates solids in routine food testing procedures.
• Inorganic Analysis Used across construction, mining, and steel industry methods for quantitative inorganic determinations.
• Sample Preparation for Instrumental Analysis Clarifies solutions prior to spectrometric and other instrumental measurements.
