Thermo Scientific SPECTRONIC 20+ Series Spectrophotometers
These Thermo Scientific SPECTRONIC 20+ Series Spectrophotometers are ideal for a wide range of research and classroom applications. Easy-to-use, reliable, and efficient. The SPECTRONIC 20D+features easy-to-read digital display, direct readout of concentration, and a simplified computer and printer interface that allows printing and RS-232C communication. The SPECTRONIC 20+ features improved 0%T and 100%T adjustments for faster settings, more stability, and greater accuracy. Its 14cm (51/2“) analog meter reads linear %T and non-linear A.
The RS-232C cable kit connects the SPECTRONIC 20D+ to an IBM*-compatible computer, or a 40-column printer. The accessory filter kit includes four stray light/second order filters and one didymium filter. Requires RS-232C cable for operation. SPECTRONIC standards kit requires 10mm square cuvette holder.
