Cleaning laboratory glassware properly is essential for accurate, safe, and repeatable lab work. This guide explains how to remove stubborn residue from beakers, flasks, bottles, volumetric glassware, and other lab glassware, including grease, dried salts, biological residue, stains, and burnt deposits. It also covers safe cleaning methods, common mistakes, drying and storage tips, and when damaged glassware should be replaced.
Pipette calibration helps laboratories confirm that liquid handling results remain accurate, repeatable, and traceable. This guide explains how pipettes are calibrated to ISO 8655 standards, including gravimetric testing, environmental control, correct tip selection, volume testing, calibration records, and common mistakes to avoid. It also covers when to use in-house calibration and when an external calibration service may be more suitable.
