Easy Microplate Viewing for Pipetting and Liquid Transfer The Pipettor Guide features a plastic sliding guide to help align your Pipetter with the microplate wells. The sliding guide is clearly marked with column letters for fast and easy orientation. The Guide is compatible with multi-channel pipetters. Use with or without the 30° angled stand. The Pipetter Guide is a great tool to reduce eyestrain and tedious pipetting work. The Pipettor Guide has been newly redesigned for ultimate versatility. Two guide heights can accommodate standard 96-well flat bottom microplates or 96-well v-bottom PCR plates.
