• For Drying, Preserving, Storing, and Shipping Samples
• Vacuum Pump Built Into Top

These plastic containers are ideal for drying, preserving, storing, and even shipping samples, including chemicals, powders, metals, foods, and electronics. Although we've found that they work best for preserving and drying your favorite mushrooms. There is a vacuum pump built into the top which removes air with manual strokes for a vacuum of better than 200 inches of water. Rubber O-ring sealed cover maintains the vacuum, and a release button on top allows air into the container to remove the lid. Use our drierite dessicant to keep your mushrooms crisp and dry.
