Pipetting Liquid into Centrifuge Tube - Laboratory Technique Guide #117108 (License: Personal Use)

This illustration shows a standard laboratory procedure where a pipette transfers a precise volume of liquid into a conical-bottom microcentrifuge tube labeled “1”. The open lid rests beside the tube, indicating readiness for sample addition or mixing. Such setups are common in DNA extraction, PCR preparation, and cell culture workflows.

Used on educational or protocol pages for life science labs, this image supports instructions for sample preparation, pipetting best practices, or equipment training-targeting students, technicians, and researchers seeking visual guidance.
