The material of Ruby capillary is divided with single and poly-crystalline Ruby.
KOSMA is producing the poly-crystalline ruby capillary and it is able to produce the various design base on customer demands because it has a good inner formation and processing characteristic than Ceramic capillary.
Also, the transmissibility of ultrasonic waves is improved and the Ruby capillary can be used under lower parameters and it is a suitable material for long life time due to high Inter-metallic and improved wear resistance.
