Weights & Accessories includes laboratory weights, weight sets, carriers, hangers, and weighing boats used for basic mass work, balance demonstrations, force experiments, and routine sample handling. This category is suitable for science classrooms, teaching laboratories, preparation rooms, and general laboratory areas where practical weighing and measurement accessories are needed.

The range includes hexagonal cast iron weights with rings, laboratory weight sets with tray and hooked experiment options, slotted iron weights with hangers, slotted brass spare weights, slotted weight carriers, and slotted weight sets with brass and aluminium components. These products support common classroom and laboratory activities such as loading experiments, balance work, mass comparison, suspended weight demonstrations, and force-related practicals.

Polystyrene weighing boats are also included for non-graduated laboratory transfer tasks. They provide a simple way to hold or transfer suitable powders, granules, or small samples during weighing and preparation work. Users should select weighing boats based on sample compatibility, size, and laboratory procedure requirements.

For technical reference, ASTM E617 covers laboratory weights and precision mass standards, including physical characteristics and metrological requirements. OIML R 111-1 covers weights of accuracy classes E1, E2, F1, F2, M1, M1-2, M2, M2-3, and M3. NIST Handbook 105-1 provides specifications and tolerances for field standard weights. These references are useful for understanding laboratory weight classification, but should not be used as product-specific calibration, accuracy, or certification claims unless supported by the manufacturer’s documentation.

For LabChoice Australia customers, Weights & Accessories provides a practical range for schools, universities, science departments, and laboratory users needing weight sets, slotted weights, hangers, spare carriers, replacement weights, and weighing boats for hands-on measurement, weighing, and teaching workflows.
