LabExact® HydroBlokr™ reduces serological pipette sample cross contamination and device failure.   HydroBlokr™ 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.
HydroBlokr™ liquid barrier has a multi-layered membranes within an ultrasonically welded device which creates a check-valve effect when wet.  The membrane immediately reacts in the presence of aqueous solution by stopping and blocking further passage.   No further aspiration is possible, and the blockage cannot be "blown out”.  It is plainly obvious the filter has become wet, and replacement is necessary.  The filters have a high-flow, less restrictive path for vacuum and positive pressure to pass extending battery and motor.  Compatible with most serological pipette and liquid handling controllers, it inserts in the device like a standard.  Once inserted the function of the filter is no different from a standard hydrophobic filter until it becomes wetted. 

Features

• HydroBlokr™ Stops, blocks and locks upon wetting to help reduce incidents of cross
  contamination via re-introduction of fluids from one aspiration to the next in serological pipette devices.
• HydroBlokr™ is an advanced filter device offering significant improvement over the
  often overlooked insufficient components in use by many operators.
• HydroBlokr™ is a multi-layer barrier which demonstrates higher retention than
  standard single layer devices.
• HydroBlokr™ creates less back pressure which helps to extend battery life and reduces wear and tear in motorized units.
• HydroBlokr™ inserts in the device similarly to that of standard filters, generally in less than 1 minute.
• Indication of need-to-replace is plainly evident by halted operation.
• Multiple design configurations are available to match the geometry of a standard filter for broad device compatibility. 
• Compatible with most serological pipette and liquid handling controllers; metered
  bulb, motorized, premium or budget, imported or domestic.
• Once inserted the function of the filter is no different from a standard hydrophobic filter until it becomes wetted.
• Porosities available: 0.80µm high-flow and 0.22µm, sterile and non-sterile versions.
