Microscope Seibert (c.1886)

Wilhelm (1840 - 1925) and Heinrich (1842 - 1907) Seibert began and trained alongside Ernst Gundlach and Edmund Hartnack in Germany in the second half of the 19th century. From 1867 to 1872 they worked as employees of the former until this year, and in collaboration with Georg Krafft, they bought the business from him after accumulating large debts due to mismanagement and emigrating to the USA. They manufactured a very good model of oil immersion objective which was very successful. After Heinrich's death, and after years of collaboration with Leitz, the company passed into their hands. By 1900 they had manufactured approximately 10,000 units.

Magnificent microscope built at the end of the 19th century in perfect condition, maintaining the final golden lacquer with hardly any marks. This specimen surely represents the culminating moment of the manufacturing stage of the Seibert brothers with specimens of great quality and beauty. The microscope is very complete, with all the original accessories and other additions from the same manufacturer and period. It has 4 eyepieces (0, I, II and III) as well as 4 objectives (0, I, II, and VII), all of them in good optical condition. Other accessories are a sub-base with diaphragm-iris and horizontal displacement, micrometer and condenser, as well as different light limiters. The serial number is 4655, which places it in 1886 and the height in the working position is 36 cm.
