Description: | For measuring the refractive index of small liquid samples. Abbe refractometer principle; device for measuring the critical angle between glass and liquid sample. Black painted brass with an iron base. The viewing barrel has an adjustable focus varying from -60 to 60 in single units, marked every ten. This looks down on 2 prisms which can be separated and have an adjustable mirror below them. The angle of the prism can be adjusted using a screw handle at the side. There is a scale, from 1.30 to 1.70 in one thousandth units marked every 0.01, and a moving magnifier. At the side there is a screw fitting where the refractometer thermometer can be fitted. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1914-1950 | Source: | University of Aberdeen | Creator: | Name slightly obscured, possibly Bellingham & Stanley | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
