Clinical scales designed for general use in the clinical laboratory; they include appropriate top surfaces, trays, or platforms. A great variety of laboratory scales exist, and their capacity ranges from 0.5 to 200 kg (1 to 440 lb), with a readability range of 1 to 100 g (0.0025 to 0.25 lb). Laboratory scales are used to determine the weight of bulk materials, solutions, or large discrete objects when it is not necessary to have the accuracy of a laboratory balance, when the weight is beyond the range of a laboratory balance, or when specimens must be weighed in special conditions (e.g., in fume hoods).
