Thermo Scientific SPECTRONIC™ 20+ and 20D+ Visible Spectrophotometers Renowned instruments for quantitative analysis ●
Included optical filters reduce stray light SPECTRONIC 20+ Analog Spectrophotometer (02660-50 and -49) features wavelength selection, power/zeroing knob, and T/A control. Analog output is adjustable from 0 to 1.0 VDC. SPECTRONIC 20D+ Digital Spectrophotometer (02660-10 and -09) simultaneously displays wavelength and either %T, A, or concentration. Determine relative concentration. 1⁄2"
What’s included: twelve diameter test tube cuvettes, sample adapter, dust cover, and a 6-ft power cord with plug (U.S. standard or European).

Jenway Visible Spectrophotometer Compact footprint takes up minimal bench space This easy-to-use spectrophotometer is ideal for the busy technician. Wavelength calibration is automatic at start-up and includes an auto-zero (% transmittance) function—a significant time saver. Spectrophotometer is fully GLP (Good Laboratory Practice) compliant. Internal software program saves date and time with each sample reading. Connect spectrophotometer to your printer or computer with optional RS-232 interface cable, then simply push the print key to send data. Use the analog output to connect the unit to a chart recorder. For more sophisticated data manipulation, optional Collect software lets you place data directly into a spreadsheet with time and date. Simultaneously read photometric result (transmittance, absorbance, concentration, or factor value) and wavelength. Dual-line LCD shows error messages, prompts, mode indication, and concentration units (ppm, mg/L, g/L, M, %, and blank). Order optional accessories and replacement parts at right. What’s included: holder for 10-mm pathlength cuvettes, 100 disposable polystyrene cuvettes (10-mm pathlength), and a 6-ft power cord.
