Whatman
Pura Disc 13mm H-PTFE Syringe Filters 0.2um, Hydrophilic, 100/Pk SKU: 6772-1302

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 13mm - 6772-1302

Eliminate the risk of microbial contamination in your upstream workflows with the Hydrophilic Polytetrafluoroethylene (PTFE) Whatman Puradisc™ Syringe Filter, 13mm, 0.2µm, 100/pk, optimized for sterile filtration protocols. Central to this performance is a hydrophobic Hydrophilic Polytetrafluoroethylene (PTFE) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Hydrophobic

• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Research & Development - Supports protocols that need to filter contaminants, providing the ability to optimize sample clarity
• Analytical Sample Prep - Optimized to ensure data integrity by effectively filtering contaminants before instrumental analysis
