The Desi-Vac™ is a plastic container with a vacuum pump that is ideal for drying, preserving, storing, and even shipping samples. Vacuum pump built into the top removes air with manual strokes, while rubber O-ring-sealed cover maintains vacuum. Achieves a vacuum of better than 200 inches of water. A release button on top allows air into the container to remove the lid.
Use dessicants to teep your powder dry—ideal for storing chemicals, powders, sample tissues, and plant sections, and for weighing samples. Diameter of all three sizes is 4-1/8 inches.
