HydroBlokr Serological Pipette Protection Filter, 0.22 µm, Male Slip, Nonsterile, 100/Pk SKU: LE-HYBK4-100

Featuring advanced multi-layered membrane technology delivering unparalleled contamination protection for serological pipette controllers and liquid handling systems. Proprietarily designed, multi-layered series of membranes placed within an ultrasonically welded device creates a check-valve effect when wet, with the functional membrane immediately reacting in presence of aqueous solution by stopping and blocking further passage. High-flow, less restrictive design allows vacuum and positive pressure to pass while extending battery and motor life compared to standard hydrophobic barrier filters.

Key Multi-Layer Membrane Characteristics

• Unique stop-block-lock mechanism halts operation and locks out further usage once wetted, unlike simple hydrophobic filters
• Highly retentive pore structure with 0.22 µm porosity provides enhanced protection for user environment
• Membrane immediately reacts to aqueous solutions by stopping fluid passage, with no possibility of blockage being "blown out"
• Multi-layer barrier construction demonstrates higher retention than standard single layer devices
• Visual indication system makes filter wetting plainly obvious, with replacement necessity clearly evident by halted operation

Key Construction Characteristics

• Universal compatibility with most serological pipette and liquid handling controllers through multiple design configurations matching standard filter geometry
• Simple installation requiring less than 1 minute for replacement, inserting similarly to standard filters
• Reduced back pressure design extends battery life and minimizes wear on motorized units
• Male slip to male slip connection configuration provides secure fitting in standard pipette controller systems
• Hydrophobic membrane construction maintains barrier integrity until activation by aqueous contact

LE-HYBK4-100 filters stop, block and lock upon wetting to dramatically reduce cross contamination incidents via fluid re-introduction between aspirations, significantly reducing the harmful effects of overdraw and accumulated wetting. Unlike traditional pipette filter barriers that become compromised after wetting and allow sample infiltration into controller handles, HydroBlokr technology immediately blocks flow in either direction upon contact. Filter halt operation clearly indicates replacement time, allowing your pipette controller to continue functioning with maintained protection integrity throughout your critical liquid handling and analytical protocols.
