ESKALAB SPECTROPHOTOMETER

Smith Kline Eskalab Spectrophotometer

This is an all-analog, early benchtop spetro-photometer for life sciences, part of the Eskalab family of prepared reagents and supplies. I guess this is a 1960s instrument. It has a 1P28 photomultiplier tube,  and uses dielectric transmission filters as its wavelength selection mechanism.  Ours had a myriad of faults and missing components, chronicled in the restoration video.
