Vial Barcode Reader Automatic method identi¡cation of barcoded sample vials is an exciting feature of HI802. The HI802 visible spectrophotometer scans an inserted barcoded vial and automatically detects both method type and method range, signi¡cantly reducing the risk of errors and aiding measurement procedure. Vial Rotation Vial rotation during measurement allows for method identi¡cation and for a number of absorbance readings. The instrument then converts the readings to concentration units and the result is shown on the LCD display. This rotational averaging of signals during measurement (with the lamp on) ensures improved method accuracy. Shared Single-Zero Measurement Use of a single-zero measurement across multiple vial methods where blank correction is done with DI water. This ensures that sample features, rather than instrument changes, are reected in the instrument’s measurements and contributes to ease of use and stable readings. 10 Photometers 10.10 | www.hannainst.com iris® Spectrophotometer
