Laboratory glassware supports preparation, measurement, transfer, storage, and drying of samples and reagents. This category covers media bottles, beakers, desiccators, funnels, Erlenmeyer (conical) flasks, volumetric flasks, pipettes (volumetric and serological), measuring cylinders, and test tubes. Items are typically manufactured from borosilicate or soda-lime glass and feature options such as graduations, GL threads, ground-glass joints, and amber variants for light-sensitive materials. A-grade and certified volumetric pieces are available for calibration traceability in analytical, teaching, and QC workflows.
