London Branch owns one of the OU's polarising microscopes that was part of the home kit for S260, which was the predecessor to S276. The Branch also has four sets of thin sections, from S236, S260, S338 and S339. S236 was the predecessor to S260, as was S338 to S369.

The microscope and/or thin sections are available on loan to Branch members, and would be a useful supplement to the virtual microscope provided for those studying S276, S339 or S369 who want some "hands on" practical experience. For those new to microscopes, a basic demonstration of their use can be arranged. Please note only two sets of thin sections may be borrowed at one time.

To arrange to borrow the microscope and/or thin sections, please email info@lougs.org.uk
