GD/X 25mm Syringe Filter, 934-AH Filteration Medium, 1.5 um (150 pcs)
Whatman SKU: 6892-2515

Whatman GD/X Glass Fiber (GF) Syringe Filters, 1.5 µm, 25 mm, 150/Pk - 6892-2515

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Glass fiber withstands high-temperature pre-conditioning up to 500°C and stays biologically inert across diverse chemistries. Polypropylene construction holds extractable contribution low for sensitive analyses while preventing sample bypass under rated operating pressure and resists degradation from routine sample matrices. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Nominal depth retention with high dirt-loading capacity
• Withstands high-temperature pre-conditioning up to 500°C
