LabExact® HydroBlokr™ is a novel filter technology which reduces serological pipette controller sample cross contamination and device failure with a check-valve effect when wet and blocks further passage of over aspirated aqueous solutions.

• LabExact® HydroBlokr™ is a novel filter technology which aids in the reduction of serological pipette sample cross contamination and device failure
• HydroBlokr™ liquid barrier functions via use of proprietarily designed, multi-layered series of membranes placed within an ultrasonically welded device which creates a check-valve effect when wet
• With six models available compatable with most controller heads
• The functional membrane within the series immediately reacts in presence of aqueous solution by stopping and blocking further passage
• The materials create a highly retentive pore structure which helps protect the user environment
• Unlike simple hydrophobic barrier filters, once HydroBlokr™ is wetted it halts operation and locks out further usage until replaced, stops, blocks and locks

No further aspiration is possible and the blockage can not be 'blown out', thus helping to protect your sample and making it plainly obvious the filter has become wet and replacement is necessary helping reduce incidents of cross contamination via re-introduction of fluids from one aspiration to the next in serological pipette devices.

The 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 with less back pressure, helping 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 and inserts in the device like standard filters, generally in less than one minute.

Porosities available: 0.80 μm high-flow and 0.22 μm.

These unique devices stop, block and lock the device requiring a filter change so operator cannot miss the possibility of cross contamination.
