HydroBlokr™ Serological Pipette Protection Device, 0.22µm, Male Slip Connection, 10/Pk SKU: LE-HYBK4-10

Featuring revolutionary multi-layered barrier technology that reduces serological pipette sample cross contamination and device failure. The advanced multi-layered series of membranes within an ultrasonically welded device creates a check-valve effect when wet, delivering unprecedented contamination control for critical liquid handling applications. The functional membrane immediately reacts in presence of aqueous solution by stopping and blocking further passage, ensuring complete sample isolation during serial aspirations.

Key Multi-Layer Membrane Characteristics

• Multi-layer barrier demonstrates higher retention than standard single layer devices while maintaining optimal flow characteristics
• 0.22µm pore size provides superior particulate retention for sterile filtration and sensitive biological applications
• Extraordinarily high flow rates compared to other simple hydrophobic barrier filters create a high-flow, less restrictive path for vacuum and positive pressure
• Once wetted, halts operation and locks out further usage until replaced, providing clear contamination indication
• Hydrophobic membrane technology resists aqueous solutions while permitting unrestricted airflow during normal operation

Key Construction Characteristics

• Ultrasonically welded housing ensures leak-proof seal and maintains structural integrity throughout extended use
• Creates less back pressure which helps to extend battery life and reduces wear and tear in motorized units
• Compatible with most serological pipette and liquid handling controllers; metered bulb, motorized, premium or budget, imported or domestic
• Inserts in the device similarly to that of standard filters, generally in less than 1 minute for rapid filter replacement
• Multiple design configurations available to match the geometry of a standard filter for broad device compatibility

LE-HYBK4-10 protection devices achieve maximum contamination prevention by completely blocking bi-directional flow upon contact with aqueous samples, eliminating the risk of sample carry-over that compromises traditional hydrophobic barriers. Indication of need-to-replace is plainly evident by halted operation, providing immediate visual confirmation when filter replacement is required. This revolutionary technology transforms your serological pipetting workflow into a fail-safe system, delivering reliable sample isolation for cell culture, molecular biology, and clinical diagnostic applications where cross-contamination prevention is critical to analytical accuracy and experimental integrity.
