Gold Seal Plain Microscope Glass Slides 25x75x1mm thick pack of 144

Package Size: 144
These water white (low fluorescence, low iron, soda lime) corrosive resistant glass slides are the highest quality manufactured. Finished slides are sealed with a desiccant in an air-tight package, keeping the slides dry during shipping and storage. This sealed environment protects against surface deterioration, spotting and sticking. All slides are precleaned and ready for use.
For UV microscopy, use the UV transparent SPI Supplies Quartz Slides.
All glass microscope slides, with time, can develop a condition called "glass corrosion", that is, the surfaces start to take on a slightly discolored and frosted appearance. So far as we know, there is nothing in the way of storage conditions that can forestall that phenomenon. We suggest not purchasing slides in quantities that larger than what you are likely to use in one year's time.
Glass slides are at times known to "stick together" and seem to pose challenging problems in terms of separating them. Again, this is a generic problem with all glass microscope slides and we offer some suggestions for their separation.
The clump of slides sticking together should be dipped in liquid nitrogen. Once cold they tend to pull apart without difficulty. If slides are washed and then stacked while still wet, this liquid nitrogen treatment solves the problem.
Another common method is to warm the stacked clump of slides on a hot plate.
Now some users of slides say this is all a lot more difficult than just using the edge of a razor blade or scalpel blade to separate them. We do not recommend that method because of the possibility of breaking off a sharp metallic edge of the blade. But if you do decide this is the method for you, be sure to wear appropriate eye protection.
