Product Description

• Hy-n-Dry stopper makes any vessel a desiccator, inexpensively. Allows sample storage for long periods, free from atmospheric moisture, even during overnight temperature changes or when refrigerating. Bottom of stopper has a porosity B (70-100 microns) sintered glass disc sealed-in. Fill stopper with 10-20 mesh drying agent, cover with plastic cap, insert into any jointed vessel. A pin hole in cap allows assembled unit to breathe with temperature fluctuations through, not around, the desiccant preventing pressure buildup.
