HydroBlokr® Serological Pipette Protection Device, 0.8µm, Female/Male Slip, 10/Pk SKU: LE-HYBK5-10

Featuring proprietary multi-layered membrane technology delivering revolutionary liquid barrier protection for serological pipette controllers. Multi-layered series of membranes placed within an ultrasonically welded device creates a check-valve effect when wet, preventing cross-contamination between aspirations and protecting expensive pipette controllers from fluid damage. 0.8µm high-flow porosity maintains optimal vacuum and positive pressure flow while providing superior contamination protection compared to traditional hydrophobic barriers.

Key Multi-Layered Membrane Characteristics

• Functional membrane immediately reacts in presence of aqueous solution by stopping and blocking further passage, eliminating fluid carryover risks
• Unlike traditional hydrophobic barriers, HydroBlokr™ immediately blocks flow in either direction upon wetting for definitive contamination prevention
• Extraordinarily high flow rates compared to other simple hydrophobic barrier filters reduce system back-pressure and extend controller battery life
• No further aspiration possible once wetted, and blockage cannot be "blown out" ensuring fail-safe operation
• Indication of need-to-replace is plainly evident by halted operation providing clear visual confirmation of filter status

Key Construction Characteristics

• Installs in less than 1 minute with standard female slip to male slip configuration for universal compatibility
• Compatible with most serological pipette and liquid handling controllers including metered bulb, motorized, premium or budget systems
• Multiple design configurations available to match standard filter geometry for broad device compatibility
• Nonsterile construction optimized for routine laboratory applications requiring contamination protection without sterility validation
• Hydrophobic surface chemistry maintains barrier integrity while allowing unrestricted airflow during normal operation

LE-HYBK5-10 devices deliver exceptional protection against the costly effects of over-aspiration while maintaining the high-flow performance critical for efficient pipetting operations. Proprietary technology stops, blocks and locks the pipette controller once wetted, significantly reducing the harmful effect of overdraw and accumulated wetting due to repeated aspiration. ASTM E934¹ compatible design ensures seamless integration with standard serological pipette workflows, transforming your liquid handling procedures with definitive cross-contamination prevention and enhanced controller protection for demanding cell culture, molecular biology, and analytical laboratory applications.
