I recently dismantled a small microplate reader and rather than just scrapping the science element of it i thought i'd offer it here in case someone could re-purpose or reuse it as it's a self-contained unit and is functional.

There is a motorised tray which loads the microplate into the system, a halogen light source passes through a selection of filters. The light then passes to the underside of the microplate through optical fibers, the light from a microplate is then collected by a series of photodiodes in an array. The control board, LCD screen and keyboard control the operation. It connects to a PC through RS232 where a small DOS app controls it entirely through serial commands. I will include the original software on 3.5" floppy disk.

looking for £25 including shipping in the UK or you can collect it from south Manchester for £20

With a bit of effort that's the beginnings of a nice X-Y table I think.

No, I don't want it, far too much on my plate right now but a very nice piece of tech.

A couple of comments

  • The insides should be soaked with 70% Isopropanol before touching with ungloved hands. These are often used in biological labs and the insides are seldom sanitized.
  • Those filters are going to be very high quality microscopy grade filters, useful for fluorescence detection or absorption detection.
  • The photodiodes are going to be very solid quality as reproducibility is going to be critical for this instrument.
  • Depending on the model, that XY stage could have EXTREMELY high accuracy and repeatability. They are designed to read and move to the exact same spot every single time at the expense of range.

Hi,

As a biomedical student interested in electronics (and currently working on such devices ... well, greatly simplified) that would be a great project to learn more!  :)
Unfortunately I'm from Belgium... If it is possible to ship it, I'd be interested.

Thanks!
