There’s no need to bother with two workstations when one will do. Spectronics’ Spectroline Bi-o-vision Series of transilluminators feature two workstations, producing both 312-nm ultraviolet and white light. The Td-1000r model offers fixed-intensity while the Tvd-1000r model offers variable intensity control of either UV or white light. They are continuously adjustable from 100 per cent down to 50 per cent and have two adjacent workstations, each with a filter area of 20 x 20 cm. Suitable for viewing fluorescent gels or visible blots. Spectronics Corporation
