Product Description

Filter paper Grade: 44, 125 mm

  • Accurate ash-free dry mass measurements
  • Fine nominal particle retention rating of 3 micro-m
  • Filtration speed (Herzberg 995 s)

Typical thickness of 180 micro-m

GE Healthcares Life Sciences business offers other ashless grades with different particle retention ratings, as well as hardened ashless grades to ensure accurate measurement during analyses of samples that are strongly acidic/alkali.

Fast gravimetric analysis of fine particles

Gravimetric analysis can be time-consuming when the filtration of fine particles is required. Because of its reduced thickness, Grade 44 ashless filter paper from GE provides faster filtration of fine particles when compared with thicker papers of similar retention rating, such as Whatman Grade 42 paper.
