4. ... the balance is ready for weighing. To calibrate the balance for the weighing range press CAL button and the display will show “C” during the calibration. Mop up any spilt liquids and brush any spilt chemicals from the weighing chamber. Good Weighing Practice™ (GWP®) ... Standard Operating Procedures for balance testing of sensitivity, repeatability and eccentricity . Weighing balances, pH meter etc.) 1.0 Objective: ... 4.14 Place the weighing vessel on the pan of the balance and tare the weight. Acceptance Criteria: ± 0.1 % of actual standard weight. Select the correct weights to test your balance, choose from 50 µg to 5000 kg and optimize your calibration processes with our accessories. 5.30 Instruments designed for calibration, weighing, monitoring, testing , that are critical for semi-finished products and pharmaceutical active substances, should be calibrated according to written procedures and set schedules. 4.3.4.1 press the cal key to start calibration. The scale should be checked with weight standards on the centre and all four corners of the pan in turn during each calibration check. weighing much smaller amounts of sample as required and might not be needed. is not necessary. Updated on: 25/03/2020. b. 5.0 Repeat steps 1.0 through 4.0 for the 1000 gram and 5000 gram weights. Weighing scales, weighing instruments, weighing balances… different resources are using different terminology. In the calibration record no activity shall be mentioned. Home Quality Control SOP for Operation and Calibration Procedure For Analytical Balance SOP for Operation and Calibration Procedure For Analytical Balance Mubarak Patel June 10, 2020. Draw the linearity curve for the above readings and find out the correlation factor. Accuracy: Check the accuracy of the balance by using following standard weight 20mg, 50mg, 100mg, 200mg, 500mg, 1g, 2g, 5g, 10g, 20g, 50g, & 100g. Clean the Weight Scale’s measuring surface, the surface the scale is laid on, and wear gloves when handling the weights to be used. Pretest Weight Cart Inspection 4.1. Whenever possible, the calibration weight range should bracket the user range of the balance. Approval Date SOP Developer: _____ 5.3 calibration : 5.3.1 daily calibration: 5.3.1.1 with the balance turned on, press and hold ‘mode’ key until “cal” is displayed. 5.3.1.4 place the indicated span calibration mass of 300g on the pan. Weighing and Calibration Procedures for Weighline 5 SETUP Soft Key Pressing the SETUP soft key first prompts you for Setpoint #1 value fol- lowed by Setpoint #2 value. Finally, most quality assurance procedures along with GLP/GLP and ISO specifications clearly specify external calibration only. 4.3.4.2 the balance display displays cal in and performs calibration.prevent vibration and drafts from affecting the balance. The XPR2 microbalance with a repeatability of 0.5 μg fulfills the requirements perfectly. In our SOP now some balances have one calibrated mass(es) and others two mass(es). Balances • Calibrate balance daily if it is equipped with an on-board internal calibration feature • Verify balance accuracy monthly with at least 2 external ASTM class 1 (“S”) weights (1 in mg range; 1 in the g range) • Record weight measurements, maintenance and corrective action in a logbook c. Keep the balance calibrated using the standard calibration procedures against daily, weekly, and monthly schedules. Repeat this exercise for 10 times. 4.15 Follow the pipetting technique as described in section 4.0. CarePac® weight sets contain only two weights – which is all that is required for routine balance testing between calibrations. If suitable testing facilities for the calibration … 7.0 If any of the weight readings are out of the scale requirements, immediately take the calibration record to the Quality Assurance Manager for their review. It should weigh … RAW MATERIAL STORE CEPHALOSPORIN BLOCK Page No. The check-weight may be any object whose mass remains constant and does not exceed the load limit of the balance. BRAWN LABORATORIES LIMITED.
