HydroBlokr Serological Pipette Protection Device, 0.8µm, Male-Male, Check-Valve, 100/Pk SKU: LE-HYBK3-100

Featuring advanced multi-layered membrane technology that creates a check-valve effect when wet, delivering superior cross-contamination protection for serological pipette controllers. Stops, blocks and locks upon wetting to help reduce cross contamination via re-introduction of fluids from one aspiration to the next in serological pipette devices. High-flow 0.80µm porosity configuration provides unrestricted vacuum and positive pressure pathways while maintaining device compatibility with most serological pipette and liquid handling controllers.

Key Membrane Protection Characteristics

• Proprietarily designed multi-layered series of membranes within ultrasonically welded housing delivers superior barrier performance over traditional single-layer filters
• No further aspiration is possible once wetted, and blockage cannot be "blown out" ensuring complete controller protection from sample infiltration
• Immediately blocks flow in either direction upon wetting unlike traditional filters that become compromised after repeated exposure
• Hydrophobic surface chemistry maintains airflow integrity during normal operation while providing instant liquid barrier activation
• Plainly evident indication of need-to-replace by halted operation eliminates guesswork and prevents accidental controller damage

Key Construction Characteristics

• Male slip connection geometry ensures broad device compatibility with standard pipette controller configurations and filter housing systems
• Creates less back pressure which helps extend battery life and reduces wear and tear in motorized units compared to restrictive traditional barriers
• Inserts in device similarly to standard filters, generally in less than 1 minute for rapid maintenance and minimal workflow disruption
• Non-sterile packaging accommodates routine laboratory applications while maintaining cost-effectiveness for high-volume usage
• Ultrasonically welded construction withstands repeated vacuum and pressure cycling without structural failure or membrane displacement

LE-HYBK3-100 devices achieve higher retention than standard single layer devices while maintaining the high-flow characteristics essential for efficient pipetting operations. Compatible with most serological pipette and liquid handling controllers including metered bulb, motorized, premium and budget models, these protection devices transform standard controllers into contamination-resistant systems. Revolutionary check-valve technology addresses the fundamental weakness of traditional hydrophobic filters, providing laboratory personnel with reliable safeguards against costly controller damage and cross-contamination incidents that compromise analytical results.
