IMIDAZOLE CHEMICAL CRYSTALS (POLARISED LIGHT MICROSCOPY) KEYRING (K10)

A solution of imidazole (a chemical which is very close in structure to the amino acid Histidine) was evaporated on a microscope slide to form crystals. By viewing these crystals using polarised light microscopy, amazing and interesting colours and patterns are seen. This is due to the crystals forming regular arrays and interfering with the light path to give the colours seen (no colours were changed using Photoshop).

Silver coloured high quality metal keyrings with a colourful dye-sublimation printed picture of a microscope image on one side that gives a durable and scratch resistant finish.

Keyrings measure 42x25mm (measured without including ring).

Supplied in a presentation box with a label describing the image.
