Brock And Michelsen Analytical Balance Appraisal

Brock & Michelsen Analytical Balance

This item is a vintage analytical balance, likely used for precise measurements in a laboratory or scientific setting. It is enclosed within a wooden and glass case designed to protect the delicate mechanism from air currents and dust, ensuring accuracy. The case appears to be constructed from a dark-stained hardwood, possibly mahogany or a similar rich-toned wood, with clear glass panels on the front, sides, and possibly the top, allowing for visibility of the internal components. The joinery of the wooden frame suggests quality craftsmanship, with visible seams indicating a careful construction. The internal balance mechanism itself is made of polished metal, predominantly stainless steel or possibly nickel-plated brass, given its reflective, silvery appearance. It features a central column supporting the balance beam, from which two pan hangers with circular weighing pans suspend. These pans also appear to be made of polished metal. On one pan, a set of small, cylindrical weights are visible, indicating the balance is either in use or set up for demonstration. Above the main balance mechanism, there is a prominent black digital display unit, suggesting a hybrid design or a later addition to an older mechanical balance, indicating either an electronic reading component or a very modern iteration of an analytical balance. Observable features include the manufacturer's name, "Brock & Michelsen Kopenhagen," inscribed on a metal plaque or label affixed to the front wooden frame above the glass door, indicating its origin. A small, black box with a round control knob is mounted on the right side of the wooden case, likely a control for the digital display or for adjusting the balance. The overall condition appears to be good for its age, though minor surface wear or patina on the wood and metal components would be typical for a vintage piece. The glass seems intact with no obvious cracks. This type of balance was commonly used from the late 19th to mid-20th century before fully electronic balances became widespread, though the digital display here indicates it could be a later model or a retrofitted one from the latter half of the 20th century.
