EXC! Calibration Good Thermo Spectronic 20D+ Spectrophotometer 340

Description: It's a pretty one. You get the pictured spectrophotometer, 5 new tubes and the 38 page operators manual on thumb drive (See my other spectronic auction too) Tested and working the calibration is good.(my reference #s2) Tested: The wavelength calibration was checked and it was better than +-1% compared to the reference unit. It zeroed correctly. It adjusted to 100% correctly and it didn't wander. The lamp is good. The zero adjust works. The 100%(span) adjust works. The lamp is bright. The wavelength adjust is smooth and even. Manu: Spectronic Instruments Model: 20D+ 33318330 Day WarrantyCosmetic Condition: On a Scale of poor/fair/good/excellent its in the low excellent category. Minor marks. Shipping: The high bidder pays only the actual shipping cost. It will be expertly packed (no packing fee). Background info from the manufacturer SPECTRONIC 20D+ Digital Model simultaneously displays wave- length and either % T, A, or concentration. Determines direct concentration readout in FACTOR mode. The meter then electronically converts absorbance values to concentration units by multiplying absorbance values by this factor. Spectrophotometers include twelve 1/2" diameter test tube cuvettes and sample adapter, operating manual, dust cover, and 6-ft cord with plug (U.S. standard or European). Included optical filters reduce stray light.
