Developed for my PhD work.
Expansion tray for use with 30mm x 25mm x 1-1.3mm glass slides. This can expand the capacity of other slide holders made for standard thin-section sized slides or can be used alone for desktop organization.
These trays fit inside a standard thin-section sized slide holder tray by stacking two rows of 100 slides. We use them in our lab for apatite fission track slides.
