The LockMailer is a tamperproof multi purpose compact container for transporting, storing, mailing or staining microscope slides. Constructed of extra-strong, clear polypropylene it holds up to 4 standard 1 x 3 in. or 25 x 75 mm slides vertically. The inside slotted channels keep slides safely separated. It incorporates a unique tamper evident leakproof screw cap made of HD polyethylene. The LockMailer can also be used without the tamperproof feature.
The LockMailer is also an efficient staining vessel; the unique design has a reduced internal volume to decrease the amount of staining solutions needed; 14 mL w/o slides. Only 12 mL for 1 slide, 10 mL for 2 slides, 8 mL for 3 slides and 6 mL for 4 slides of the staining solution is needed.
