Spectrometer, Spectronic 20 (ChemPages Lab)   
(Instructional Material (1))
Spectrometer, Spectronic 20?: this is a resource in the collection "ChemPages Laboratory Resources". The Spectronic 20? is used to measure the absorbance (or transmittance) of solutions. A Spectronic 20? is capable of measuring % transmittance and absorbance over the range of 340 to 950 nm (the range 600 to 950 nm requires a special infrared filter and a different lamp). The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
Spectrophotometer, Scanning UV-Visible (ChemPages Lab)   
(Instructional Material (1))
Spectrophotometer, Scanning UV/Visible: this is a resource in the collection "ChemPages Laboratory Resources". A scanning ultraviolet/visible (UV/Vis) spectrophotometer operates on the same principles as a Spectronic 20?. They both can be used for qualitative and quantitative analysis. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
