Glass Fiber Syringe Filters w/ GD-4 Pre Filter, 1.0um , 25mm, Nonsterile, 100/Pk
Tisch SKU: GD17171

Tisch Scientific Glass Fiber (GF) Syringe Filters, 1 µm, 25 mm, 100/Pk - GD17171

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Naturally hydrophilic glass fiber wets rapidly with aqueous samples while tolerating repeated high-temperature conditioning cycles and resists chemical attack across diverse solvents. The PP housing keeps the fluid path low in extractable contamination while preventing sample bypass under rated operating pressure and maintains a low-dead-volume internal flow path. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Inorganic construction suits demanding sample-preparation chemistries
• Nominal depth retention with high dirt-loading capacity
• Naturally hydrophilic surface wets rapidly with aqueous samples
• Biologically inert borosilicate fiber with broad chemical compatibility
• Withstands high-temperature pre-conditioning up to 500°C

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Tough polypropylene body tolerates repeated handling at the bench
• Resists stress cracking from aqueous salt and buffer solutions
• Plasticizer-free polyolefin construction keeps the fluid path clean

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
