Thwing-Albert Vapometer Cup Design Upgraded for Easier Sample Setup

Thwing-Albert Instrument Company has redesigned the Vapometer Cup for easier sample setup in the lab.  No more individual screws to tighten!  The original design of the Vapometer Cup used six knurled head screws to secure the flange in place.  Now, customers can find relief from the elimination of the need to secure 6 individual screws.  Thwing-Albert’s new 68-3000 EZ-Cup design consists of a lightweight aluminum cup and aluminum threaded flanged ring with two neoprene gaskets with a Teflon seal that hold the specimen in place. This design was specifically created to eliminate edge leakage and to provide fast secure sealing of the specimen between the gaskets.  Specimens are easily loaded and sealed in place by twisting the threaded upper aluminum flange in place.

Thwing-Albert Vapometer Cups comply with the ASTM E96 standard.  Samples up to 3 mm (1/8 in.) thick can be tested with this Vapometer model.  The cups are 63.5 mm (2.5 in.) wide and 50.8 mm (2 in.) deep.  This model will save operator time and increase productivity by cutting the setup time in half.  Serialization has been added to the Vapometer to allow test administrators to easily track the results of multiple samples.   

The Vapometer is used for determining the water vapor permeability of sheet materials such as specialty paper grades, polyethylene, building material, leather, weatherproof clothing, vinyl, foil, laminates and other thin sheet materials. This property is essential in determining if a material is moisture-proof or has the ability to protect contents from the transmission of water vapor.
