Heavy, clear soda-lime glass jars have a standard screw threaded neck and a linerless white polypropylene cap that reduces solvent evaporation and spills during storage.

Wide, flat, circular base facilitates manipulation of sections attached to slides. Screw cap permits sealing jar for preservation and minimum loss through evaporation. The smaller jar holds ten 75 x 25 mm (3 x 1") slides, which extend above the opening allowing for manipulation without forceps. The larger jar holds five 75 x 25 mm (3 x 1") slides vertically or 10 slides back-to-back.
