Protecting pipette liquids from particles and microorganisms is a top priority in many laboratories - when preparing samples, dispensing media and buffer solutions or when conducting microbiological analyses with non-pathogenic microorganisms, to name but a few examples. BRAND’s automatic "Liquid Handling Station flow" pipetting system on show at LABVOLUTION 2019 is designed to make this process easier. Closing the gap between electronic pipettes and costly pipetting robots, this innovation provides laboratories with their very own compact cleanroom.

The newly developed FlowBox in "Liquid Handling Station flow" ensures the work area is kept clean. When the door is closed, the drawn-in air passes through an HEPA filter (HEPA 14 to DIN EN 1822) and is subsequently directed via laminar horizontal layers across the consumables before exiting via special openings in the front door. All the while, the air inside the cabinet is cleaned and replaced 260 or so times per hour, thereby adhering to the cleanroom specifications set out in ISO 14 644-1 (Class 5) and GMP Annex 1 (Class A). But that's not all. Before pipetting begins, the software initiates a three-minute rinsing process using cleaned air, which ensures particles (particle sizes 0.5 μm to 5 μm) are no longer detectable. What's more, the air flow automatically increases as the front door opens, providing the samples with extra protection during this procedure too. "Liquid Handling Station flow" is of course designed to offer the well-established benefits of BRAND's Liquid Handling Station. The solution requires very little space and is quick and easy to use. After just a few clicks of the mouse, the pipetting process can begin in line with the lab worker’s specific requirements.
