Superlab Bundasmann Tester - Advanced Water Repellency Assessment Apparatus , Four Sample Holders With Adjustable Tilt And Transparent Testing Window

Determination of water repellency, resistance to wetting (in term of water absorb) and resistance to penetration (in tern of water penetrated) of fabric done by an instrument known as Bundasmann type apparatus.

The SUPERLAB Bundasmann Tester apparatus is made of four specimen holders, which holds four specimens of fabric under test, the specimen holders are rotated at the fixed. RMP by means of a worm reduction gear box and an electric motor. The four specimen holders are mounted on the assembly so that the specimens are tilted at specified angle to the horizontal. Each sample holder are provided with four wiper arms fixed at right angle to each other and rotating about the axis of the cup. There are two tanks one at the bottom where the sample holder assembly is fixed and the other is fitted at the top of the instrument, where the brass jets are fitted. The water flows from the lower tank to the upper tank by means of a centrifugal pump. There are gate valve for drain the water from the lower tank. The transparent glass is mounted on the window for the transparency of the sample in testing while the window is closed.
