Laboratory Techniques Wall Chart, 75 x 100 cm

This reference wall chart gathers the foundational techniques of laboratory work onto a single sheet, giving students and instructors a quick visual guide to the procedures used across a general science lab. Measuring 75 x 100 cm, it is printed in color on a polyart plastic sheet and fitted with a plastic roller for hanging and rolled storage, a format suited to repeated classroom use.

The chart is organized into clearly bordered panels, each walking through one procedure step by step. Opening sections cover measuring liquid volumes, including reading a graduated cylinder at the meniscus and the distinct roles of beakers, volumetric flasks, and volumetric pipets, alongside weighing solids and the common balance types, from two-pan and triple-beam to electronic and analytical, with correct weighing practice noted throughout.

Further panels demonstrate lighting and adjusting a laboratory burner, including how to recognize a correctly adjusted flame, collecting gas by water displacement, and setting up a distillation. Glass-working techniques are illustrated as well, showing how to cut, fire-polish, and bend glass tubing safely.

Additional sections detail heating a liquid without bumping, filtering and decanting with folded filter paper, using beaker and crucible tongs, transferring liquids and solids, correct pipetting technique with the standing caution never to pipet by mouth, and manipulating a buret stopcock to dispense dropwise near the endpoint of a titration. Closing panels address lab housekeeping, cleaning and drying glassware, and a labeled reference of common laboratory equipment, so the chart works as both a procedure guide and an equipment identification aid.
