Our 5 compartment comparison tray with dimples allows for easy comparison between multiple samples. Each compartment has an easy transfer flap which enables the user to move the sample back to the storage envelope or vial after viewing. The small dimple allows for testing or placement of grains of particular interest. The wide edge allows the user to write the depth or other information on it to ensure samples are not mixed up. Works great under a microscope. Available in three colours: black, white or clear.
