5Y Series 1 µg Microbalance
Model: XA 5Y.M.A / MYA 5YReadability down to 1 µg (0.001 mg) for weighing active pharmaceutical ingredients, reference standards and trace impurities. A built-in ionizer neutralises electrostatic charge during every weighing cycle, while automatic levelling and internal adjustment deliver a stabilisation time of about 3.5 s. Compliant with 21 CFR Part 11 and EU GMP Annex 11, with audit trail, user management and data encryption — ready for LIMS integration. The 5Y series is designed and manufactured by RADWAG.
