The LockMailer is a tamper-proof multi-purpose compact container for transporting, storing, mailing or staining microscope slides. It is constructed of extra-strong and clear polypropylene and will hold up to 4 standard 1x3" or 25x75mm slides vertically. The inside slotted channels will keep the slide safely separated. It incorporates a unique tamper-evident leakproof screw cap made of HD polyethylene. The tamper-evident screw cap avoids manipulation of slides without your knowledge. The LockMailer can also be used without the tamper-proof feature. The caps on the LockMailer can be colour coded with the optional Capinserts, available in different colors: blue, gray, green, lilac and orange. The Capinsert is inserted in the top of the cap and has a write frosted area for sample identification.
The LockMailer is also an efficient staining vessel: the unique design has a reduced internal volume to decrease the amount of staining solutions needed; 14mL w/o slides. Only 12mL for 1 slide, 10mL for 2 slides, 8mL for 3 slides and 6mL for 4 slides of the staining solution is needed.
