These risks include the handling of hot glassware for an extended period, often three to eight consecutive minutes, depending on the sample; the use of a liquid-in-glass thermometer for an extended period; and the possibility of incurring a repetitive stress injury RSI risk, if multiple samples are to be tested. Using the semi-automatic apparatus eliminated the constant wrist movement while testing, requiring the operator to only prepare the apparatus and record the result.
