Laboratory Plasticware

Polypropylene suits general use and autoclaving, while polystyrene is common for disposable petri dishes and single-use items.

Not all plastics resist every solvent, so check a compatibility chart before using plasticware with strong acids or organic solvents.

Reusable plasticware saves money over time, while disposable items reduce contamination risk between samples.

Stock a spread of sizes, from small tubes to large beakers, to cover the full range of practical work.

Good quality graduated plasticware is accurate enough for most classroom and general lab work, though glass remains the standard for the most precise volumetric measurements.

Polypropylene items are generally autoclave-safe, but always check the specific product's temperature rating first, since some plastics soften or deform under autoclave heat.

No, resistance varies by plastic type. Always check a chemical compatibility chart before using plasticware with strong acids, bases, or organic solvents.

Many plastic items like beakers and flasks are reusable and can be washed, while items like petri dishes and pipette tips are designed for single use only.

Plastic is unbreakable, lightweight, and often cheaper, making it a practical choice for busy classrooms or fieldwork where glass is a risk.
