Desi-Vac™ Containers

Desi-Vacâ„¢ Containers

Plastic container with a vacuum pump is ideal for drying, preserving, storing and even shipping samples. Vacuum pump built into the top removes air with manual strokes. Rubber O-ring-sealed cover maintains vacuum.

Achieves a vacuum of better than 200 inches of water (15 inches of mercury). A release button on top allows air into the container to remove the lid. Sample Humidity Sponges™ desiccant drying packets are included with the larger, rectangular containers.

Keep your powder dry
Ideal for storing chemicals, powders, tissues, plant sections, electronics and weighing samples. Vacuum and desiccants keep material dry.

Humidity Sponge™

Regenerable/Indicator

Humidity Spongeâ„¢ Humidity Sponges™ meet all drying requirements
The latest in drying technology turns any container into a desiccator. Indicator bag particles show when moisture capacity has been reached.

Nontoxic and ideal for clean rooms
Humidity Sponges™ meet FDA requirements for use in direct contact with food and drugs. Desiccant (sodium calcium aluminosilicate hydrate) is nontoxic and is a GRAS (Generally Recognized as Safe) material. Ideal for storing food/pharmaceutical samples, electronics, PC boards, optics, chemicals and equipment. Outer material is made of DuPont’s Tyvek breathable, high-density polyethylene. Zero-Dust bags are certified as Class M3.5 (formerly Class 100) clean room compatible.

Retains 16% moisture, guaranteed
Drying capability depends on volume, temperature and moisture. As a benchmark, one bag will maintain dry conditions in a container with a volume of two gallons (476 cubic inches/7800 cubic centimeters). Bags are guaranteed to retain 16% moisture by weight; typical results are 37% moisture absorption. Each bag measures 3 x 3 x 1/4 inches and weight is 3/8 ounce.

Indicator Humidity Sponges™
Indicator Sponge has one side of clear film and one of white TTY. It contains blue particles which turn pink when the desiccant has reached its moisture capacity and needs to be replaced. Indicator Humidity Sponge™ cannot be regenerated.

Regenerable Humidity Sponges™
Regenerable Sponge has white Tyvek on both sides and may be regenerated and reused continuously. Regeneration requires heating in an oven at 220°F (104°C). Included in each pack is a Relative Humidity Card which changes from blue to pink to show when bags need to be regenerated.

Traceable® Humidity-On-A-Card

Traceable® Humidity-On-A-Card

Unique humidity card indicates both the current humidity and the maximum humidity attained. Easy-to-read cards are ideal for use with bottles, chemicals, plastic bags, electronics, desiccators and storage containers. Easily monitor humidity levels in shipments, optics and packaging.

Colors change as humidity rises/falls.
Dual ranges are Current and Maximum. Current range is 0 to 100% relative humidity. Color changes from blue to lavender in increments of 10% RH. Reversible indicator changes color as the humidity increases and decreasses. Readable to an accuracy of ±5% RH at 75°F (24°C).

 
Shows maximum RH% reached.
Maximum relative humidity attained is indicated by the highest numbered hole containing dissolved crystals. Dissolved crystals cause the paper around the hole to turn blue. Once dissolved, the reading will not change. (NOTE: for crystals to dissolve properly, the humidity must be maintained at or above the indicated value for a minimum of 24 hours). Each card is individually sealed in a clear moisture-barrier bag with a Humidity Sponge™ desiccant to keep the card dry and provide for an extended shelf life. To assure accuracy an individually serial-numbered Traceable® Certificate is provided. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Card size is 4 x 4 inches.
