Watch Glasses are shallow polypropylene laboratory covers used for protecting beakers, holding small samples, covering prepared liquids, and supporting simple evaporation or observation work where plasticware is suitable. This pack includes 75 mm polypropylene watch glasses, supplied in a pack of 10 for routine classroom, preparation room, and general laboratory use.
The lightweight polypropylene construction makes these watch glasses easy to handle and less prone to breakage than glass alternatives. They are practical for schools, universities, and busy bench areas where users need a simple cover for beakers or a small surface for non-critical sample handling. The 75 mm size suits everyday laboratory tasks where compact coverage or small-item holding is required.
Polypropylene watch glasses are useful for covering beakers to reduce dust entry, limit splash during gentle handling, hold small solid samples, or support short-term bench observation. They should be selected only where PP is compatible with the liquid, sample, cleaning method, and temperature involved. For higher heat, aggressive chemicals, or precision evaporation work, users should confirm suitability before use.
For best practice, watch glasses should be cleaned after use, stored flat or stacked carefully, and inspected for warping, staining, or surface damage. They should not be used with incompatible solvents, strong oxidising chemicals, or conditions outside the supplier’s stated material limits. ASTM D4101 covers polypropylene materials suitable for injection moulding and extrusion, while ASTM D543 covers evaluation of plastic resistance to chemical reagents. These references support the material-selection context only and should not be used as product-specific compliance claims unless supported by manufacturer documentation.
For LabChoice Australia customers, Watch Glasses provide a practical, low-cost choice for Australian schools, universities, laboratories, and preparation areas needing 75 mm polypropylene covers for routine beaker covering, small sample holding, and everyday bench organisation.
