Zeiss Ikon - Crecelius & Seifert - Medizinisches Instrument - D Blutzucker-Kolorimeter nach Crecelius-Seifert - Metall, Glas, Bakelit - Blutzucker-Analysator

Seltenes Zeiss Ikon D Blutzucker-Kolorimeter nach Crecelius-Seifert, Deutschland, dating to approximately the 1940s.

Developed for the colorimetric determination of blood glucose, this optical laboratory instrument was used to compare the colour intensity of chemically treated blood samples with a calibrated reference standard, representing an important stage in the evolution of medical diagnostics before the advent of electronic glucose measurement.

Manufactured in painted metal and optical glass, the instrument is presented in its original fitted case with burgundy lining. The optical components and lenses have been inspected and are clear and functional (einwandfrei). The instrument retains its characteristic industrial design and scientific appeal. Measuring approximately 16.7 × 10.5 cm and weighing about 630 g, it is both an attractive display piece and a historically significant example of early laboratory technology.

A rare and increasingly sought-after instrument for collectors of scientific, medical and optical antiques.

The instrument will be carefully packed with ample protective materials and shipped fully insured and with tracking to ensure safe delivery.
