Experiment 1 - Use of the Analytical Balance Analytical balances should only be used by trained personnel, and require regular calibration and maintenance. This laboratory experiment aims to familiarize the students on the proper use of the analytical balance, to study the A&D Weighing. To use the analytical balance effectively, the analyst must have a thorough knowledge of the construction, design, and operation of the balance. Shopping for an analytical balance requires being familiar with some of the advanced features available today as well as the proper use of these precision instruments. 8.2.2 Procedure for Mettler XS205 (#2) 1. As per USP, balance calibration parameters are Internal adjustments, Linearity, Sensitivity, Repeatability (Uncertainty), and Accuracy, etc. 2. Press ADJUST INTERNAL in the bottom left hand corner of the screen. An ISO 9001:2008 manufacturer, OHAUS lab balances, industrial scales, lab equipment and lab instruments are precise, reliable and affordable, and backed … Press the ‘tare’ button and wait for a ‘*’ or a similar symbol to appear on any of the top corners. OHAUS Corporation is a leading manufacturer of an extensive line of weighing scales, lab equipment, lab instruments, calibration weights and printers that meet the weighing, sample processing and measurement needs of various industries. And because of the fact that the weighing pan on an analytical balance is covered by a draft shield, they are not considered to be a 'top loading' balance. Experiment 1 - Use of the Analytical Balance - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Use gloves when handling heavy weights. 3. – Use an ionizing blower to neutralize static electricity as needed. Ensure all doors are closed, the balance is zeroed, and that there is nothing on the balance. Turn off the power switch and remove the power cord during cleaning. A balance is an integral component of lab work, and choosing the correct equipment is essential to obtaining efficient performance and accurate results. SOP for Analytical Balance: Operation and Calibration 1.0 PURPOSE Analytical Balance and Pipette Calibration Check Laboratory Notebook. Eliminate the temperature difference between a sample and the environment. Check the balance leveling gauge to make sure bubble is inside the target. A balance compares the mass of two sets of objects, while a scale determines the mass of an object or set of objects. Basic lab balances are used for routine measurements of solid and liquid chemicals, whereas analytical balances can be used for sub-milligram measurements with high accuracy and precision. The difference between a balance and scale is typically capacity and readability. 2. You can use automatic internal calibration (isoCAL) but additionally to this, it is recommended to calibrate the balance with external certified weights as well. The analytical balance is used to measure the mass of objects and chemicals until the 0.0001 gram accurately and precisely. Buy Analytical Balance from Able Scale for your Laboratories. This is why analytical balances have draft shields. Most analytical balances are so accurate, even just minor breezes caused by someone walking by would disrupt the reading. Free shipping on many items | Browse your favorite brands | affordable prices. Because of this, they are generally set up in a separate, interior room of the laboratory, out of the way of general foot traffic, chemical spills, flying objects, vibrations, and other disturbances. Repeat the same step for all the other weights. How to Use the Analytical Balance 7. Typically balances use a force restoration mechanism that when a force is applied (i.e. If using an electronic balance, allow to warm up for at least 60 minutes. CHAPTER II METHODOLOGY Materials and Equipments Analytical Balance Soft cotton cloth Coupon bond (substance 20, divided into 4 equal parts) Presto Cream Vanilla Sandwich Cookies three (3) one peso, five peso, and ten peso coins (one is placed at room temperature, one in cold temperature and the other exposed under direct sunlight) How to Use the Analytical Balance 1.

This mass, accurate to the nearest 0.1 mg, can be stated in your laboratory reports. Furthermore, the correct use and interpretation of measurements made with the balance is dependent on the understanding of the absolute precision with which samples can be weighed. balance in subsequent use will promote the reliability of your weighing results. Record the observations in Monthly calibration record of analytical balance. If there is a problem, use the underhook on the bottom of the balance to suspend the material away from the influence of the magnet. 4. They use an electromagnet to generate a force to counter the sample being measured and outputs the result by measuring the force needed to achieve balance. Its readability ranges between 0.1- 0.01 mg. Due to its sensitivity, it comes with a draft shield that prevents air currents from affecting the measurement of small samples.
