Scientific Instrument Auctions & Valuation

We hold three specialist auctions for Scientific Instruments each year and offer fre pre-sale valuations Monday to Friday 9am-5pm by appointment.

We advise on a wide range of items from microscopes, slides, telescopes, barometers and drawing instruments. Binocular microscopes are especially popular, with some fetching thousands, when complete with their fittings and cases. Rare examples of sundials by famous makes such as John Rowley are always worth looking out for.

Naval instruments such as sextants and octants have always been desirable items for collectors and are a regular feature in our auctions. Although sat-nav is now king, these incredible instruments helped our Navy and Merchant fleets, navigate the worlds oceans for centuries

Barometers and barographs combine science and aesthetics. Elegant classics, such as the stick barometer are still much sought after by our buyers. Orreries and Globes have fascinated scientific collectors and enthusiasts for centuries and are also highly desirable. 

If you are thinking or selling items please call us on 0191 4303000 or fill out the form below and we will reply, usually within 48 hours.

Scientific Instrument Valuations

Auction is always the best way to realise the true value of your possessions.

All of our Scientific Instrument auctions offer live online bidding which, together with our extensive worldwide database of collectors, dealers and enthusiasts, ensures that your items have every opportunity to obtain the best possible price. We act as your agent at all times and are here to maximise your return, for which we take a fixed percentage commission.

Please be wary of firms that recommend that you don't sell at auction, but instead, steer you towards selling privately, for a fixed price, to their 'awaiting buyers/collector's'.  They themselves are often the ones actually buying the items from you, at a less than generous price, to sell on for a large profit.

Fill out the online valuation form below for a free pre-sale estimate or ring 0191 430 3000 to arrange a valuation at our Newcastle salesroom.
