Chemistry Related Antique Optical Instruments |
On this web page, you will see my collection of early optical instruments used in the chemical laboratory. The collection consist of spectroscopes, refractometers, polarimeters, and microscopes made specifically for use with chemicals. The instruments date from the late 19th to the early 20th century.Elsewhere on this web site, you can see my more extensive collection of antique brass microscopes dating from the end of the 18th to the beginning of the 20th century. I am always interested in acquiring new scientific instruments for these collections and will answer all inquiries. click on the images for more information |
