Whatman 1821-070 Glass Microfiber Binder Free Filter, 1 Micron, 12 s/100mL Flow Rate, Grade GF/B, 7.0cm Diameter (Pack of 100)

• Diameter: 7.0cm
• Grade GF/B; retention: 1.0µm
• Three times thicker than Whatman grade GF/A, higher wet strength; significantly increased loading capacity
• Combines fine particle retention with good flow rate; particularly useful where liquid clarification or solids quantification is required for heavily loaded fine particulate suspensions
• Can be used as a finely retentive membrane prefilter; used in LSC techniques where high loading capacity is required

Highly resistant to chemical attack; absence of binders ensures that no impurities or changes arise from source. Unaffected by and will not denature biological/biochemical fluids; does not absorb macromolecules even at very low molecular concentrations and are easily sterilized. Wide, useful temperature range which can be used at 500°C and at low temperatures.
