Wisetube with Built in Desiccant Flip Top Cap

Wisetube Tube with Flip Top Cap
With Built in Desiccant Flip-Top Cap

This Desiccative functional tube is composed of strong and durable PP/PE plastic. The desiccant itself is built into the flip-top cap and is easy to open, it prevents healthcare and diagnostic reagent products from moisture damage and extends shelf-life. The cap’s desiccant is composed of white silica gel housed underneath the cap. This type of desiccant tube is widely used in products such as urinalysis testing strips, pH tests and other reagents so that their readings are as accurate as possible. It can also be utilized to protect camera film, cigars and other food products that require tube-shaped packaging and protection from moisture and other external elements.
