HydroBlokr® Pipette Protection Filter, 0.22µm, Female Slip/Male Slip, Nonsterile, 100/Pk SKU: LE-HYBK6-100

Featuring proprietarily designed, multi-layered series of membranes placed within an ultrasonically welded device which creates a check-valve effect when wet, delivering revolutionary protection against serological pipette cross-contamination and controller damage. The functional membrane within the series immediately reacts in presence of aqueous solution by stopping and blocking further passage, while extraordinarily high flow rates compared to other simple hydrophobic barrier filters creates a high-flow, less restrictive path for vacuum and positive pressure to pass. This 0.22µm hydrophobic barrier technology transforms standard pipetting operations into contamination-resistant protocols, preventing fluid re-introduction between aspirations while extending controller battery and motor life.

Key Multi-Layer Membrane Characteristics

• Once HydroBlokr™ is wetted it halts operation and locks out further usage until replaced, eliminating cross-contamination risks from compromised barriers
• 0.22µm pore size delivers precise particulate retention while maintaining optimal airflow for high-volume liquid handling applications
• Hydrophobic surface chemistry resists wetting during normal operation, providing reliable barrier protection until aqueous contact occurs
• The materials create a highly retentive pore structure which helps protect the user environment from aerosol contamination during aspiration cycles
• Immediate visual indication of filter saturation eliminates guesswork, ensuring timely replacement and maintaining sample integrity

Key Construction Characteristics

• HydroBlokr™ inserts in the device similarly to that of standard filters, generally in less than 1 minute for rapid changeout and minimal workflow disruption
• Compatible with most serological pipette and liquid handling controllers; metered bulb, motorized, premium or budget, imported or domestic configurations
• Female slip inlet and male slip outlet connections accommodate standard pipette controller interfaces without adapters or modifications
• Ultrasonically welded housing construction ensures leak-proof performance and maintains structural integrity during pressure cycling
• Nonsterile configuration optimized for general laboratory applications where sterility is not required, reducing cost per unit

LE-HYBK6-100 filters achieve superior contamination prevention through permanent blockage technology, eliminating the compromise inherent in traditional hydrophobic barriers that continue allowing flow after wetting. Indication of need-to-replace is plainly evident by halted operation, accelerating your quality control protocols while protecting valuable samples and expensive controllers. Revolutionary check-valve membrane technology maximizes your laboratory safety margins, providing fail-safe protection that transforms routine pipetting into validated contamination-control procedures for cell culture, molecular biology, and analytical chemistry applications demanding absolute sample integrity.
