The LP Sampler™ (Large Particle Sampler – Union Biometrica) is an automated sample introduction device, which we use to transfer zebrafish larvae from 96 well format into the VAST BioImagerTM and back into a 96 well daughter plate. The LP Sampler™ can handle objects, which range from 10 to 1500 microns in diameter and it is also capable to load from and dispense into a variety of standard plates including 24, 96 and 384 well format.
