Ruby Rods

Sapphire plunger rods is made of synthetic corundum single crystal which has good wear resistance, corrosion resistance, thermal conductivity and chemical stability. We can provide plunger rods of various materials according to customer’s needs, such as alumina ceramics and zirconia ceramics, and plunger rod assemblies with stainless steel jackets.

Mainly used in high performance liquid chromatography pumps, medical analysis pumps, petroleum pumps and various high-pressure, low-pressure pumps, etc.


Ruby rods can have various uses and applications, including:

Laser Technology: Ruby rods have been used as gain media in some types of lasers, particularly in older laser systems. The ruby laser, invented in 1960, was one of the first lasers to be developed and used a synthetic ruby rod as its gain medium.

Industrial Applications: Ruby rods are sometimes used in industrial applications for their hardness and resistance to wear. They can be used as bearings, in cutting tools, and for other precision instruments.

Scientific Instruments: Ruby rods have been used in certain scientific instruments, such as spectroscopes, due to their ability to transmit light in a specific wavelength range.

It’s important to note that the term “ruby rods” is not specific to a particular product or application but rather describes rods made from the gemstone ruby, which can be utilized in various ways depending on their size, quality, and characteristics. The specific use of ruby rods can vary widely, from aesthetic and ornamental to highly technical and industrial.
