Procedure for Micro Balance Operation and Calibration 1.0 PURPOSE: To describe the procedure for operation, calibration, and performance check of the Micro Balance. Weighing should be performed using a balance that is calibrated over the operating range and meets the requirements defined for repeatability and accuracy. • ±1x10-6 per degree Celsius or: ... • Use below balance weighing 24. Wait till zero reading is displayed on the screen. Detailed guidance on the balances can be learned through OIMLR76-1 Non-automatic Weighing Instruments. If any balance has operating range from 0.01 mg to 110 gm then it should be used for weighing the material from 0.01X50 = 0.50 mg to 110X80% = 88.00 gm. Avoid errors Non-level balance One of the worst errors that occurs during weighing is caused when the balance is out of level. … S.R., There are three terms being used for balances. Analytical Scale Calibration using a set of standard weights. To lay down the procedure for the calibration of weighing balances. Before calibrating the balance, clean the weighing platforms. USP chapter 41 “Weights and balances” has been revised recently in 2013 for repeatability and accuracy of weighing balances This USP chapter 41 makes it mandatory for pharmaceutical manufacturers to use use a test weight between 5% and 100% of balance capacity . SOP Number . 2. It can be stated that there are no two homogenous weighing processes, there are various models of balances in use, dynamics of ambient conditions changes is different, and different samples are weighed.

T.1.2.5 Non-self-indicating instrument . range of testing to simulate your production process options and provide assurance that systems and operating documentation are capable of subsequent process validation activities. Per USP <791> pH, purchased buffers traceable to NIST and having a stated pH value accurate to 0.02 pH may be used. As the new USP Chapter 41 requirements do not differ very much from those of the former chapter, you can expect that your balance will meet these new ones. 3. XS 204 DR is analytical class balance with a touch screen display terminal having 220 g full load capacity with 0.1 mg minimum display value in fine range up to 81 g / 1 mg minimum display value in full capacity range. Standard Operating Procedure for Calibration and Maintenance of Weigh Balances. Even the slightest breeze or vibration can affect the readings. USP Chapter 41 now defines that weighing shall be performed using a balance that is calibrated over the operating range and meets the requirements defined for repeatability and accuracy . device. EQ-03-08 Date Revised 02-03-17 Page 1 of 6 . Record the range values in a suitable control chart for weight cart calibrations. 2.0 SCOPE: The SOP applies to […] Allow to stabilize for 15 … Scope: Applicable to all weighing balances except analytical balances. Analytical balances are accurate and actual equipment used to evaluate public. 0.41d8*000 to balance max. Use the trolley balance for material weighing within its verification range only. September 2013 25 ααα 400µm. Switch ON the balance. T.1.2.5 Non-self-indicating instrument . Responsibility: Department Head. It is used to establish and or confirm; 1. The mandatory General Chapter <41>, "Balances", describes three key requirements that a balance needs to fulfill when weighing analytes for quantitative measures: weighing should be performed on a calibrated balance that meets repeatability and accuracy requirements. Instrument with a self-indicating weighing range, in which the operator intervenes to alter the limits of this range. USP (United States Pharmacopeia) defines a weighing guideline that uses a minimum weight requirement; however, it is important to note that while this particular guideline is only relevant for pharmaceutical laboratories which must be in compliance with USP, it is only one example of a minimum weight guideline and is not the sole definition. If the balance power has gone off and then has come back on, as in a power outage, certain types of balance may display a message indicating that the balance must be calibrated before a weighing is made. so operating range 82 - 220 g. SOP No. T.1.2.6 Electronic instrument . Title Calibration and Maintenance of Weigh Balances Scope Describes process for use, calibration, and quality control of weigh balances and reference weights. It is even possible that you are allowed to weigh even smaller amounts under the new regulations. USP Chapter 41 does not reference minimum sample weight any longer, rather it defines Repeatability and Accuracy, which is of crucial importance to determine the Operating Range of a balance. The start point (which can be compared to what was … that operating conditions of such balances do not have to be as strict as, for example, in case of microbalances. But according to USP <41> Weights and Balances, a simple theoretical calculation can be used to calculate the minimum weight for any balance … However the case may vary depending on the organizations views and the availability of balances for a wide renge of weighing porposes with different precisions/ accuracy level requirements. Unless otherwise specified, when substances must be “accurately weighed”, the weighing should be performed using a balance that is calibrated over the operating range and meets the requirements defined for repeatability and accuracy.” This is accomplished by defining and requiring the observance of a minimum weight standard as defined in USP Chapter 1251. They are recommended for calibration of balances using optical or electrical methods for accurately weighing quantities below 20 mg. Instrument in which the position of equilibrium is obtained entirely by the operator. They are meant to detect very fine increments of the materials being weighed. Repeatability The new USP requires that the repeatability of a balance be determined based on at least 10 comparable weighed val-ues. They are available in various denominations from 1 to 500 mg. … T.1.2.6 Electronic instrument . The tolerance for any denomination in this class is 5 µg. From primary to complicated analytical with a weight of programs, Essae Analytical balances are the right choice for your business. Thermo Scientific Orion pH buffers meet these criteria. They have a readability range between 0.1mg – 0.01mg. Ensure that the standard weights used for verification and calibration are within the range and within the due date of certification. Set the standard weights for various balances based on the capacity of the balance as mentioned in table – I. In the revised Chapter 41, the USP does not refer to a minimum weight; this has been replaced by the requirement to determine the balance’s ‘operating range’, which is limited above and below by the maximum capacity of the balance and begins at the point at which the balance’s repeatability is less than or equal to 0.10%. Power Supply: DC Adaptor,input 100 ~ 240 0.8A output 13V / 15.A, 50-60Hz: Compliance: ISO, GLP / GMP USP Compliance: Balance Size (W x D X H) mm: 342.5 x 212 x 341 / Chamber Height 228.5: Weight Approx: 9.3 kg Weighing balances, 1) Do we require to establish 'operating range' ; If yes, what are the principles/requirements and references outlining the same. wide range of balances and scales. this has been accepted and is a un written rule followed as per my knowledge. Measurement Good Practice Guide No. The frequency of the balance check depends on the risk of the application and the required weighing tolerance." If a the balance will not be damaged. Determine the calculated differences per SOP 8 and calculate the range between the largest and smallest numerical mass value differences.
