Product Description

Getter Alkali Metals Dispensers


This series is a composite getter-type alkali metal release agent made of alkali metal salt and non-evaporable getter powder pressed into a metal carrier. It is to meet the special needs of photomultiplier tubes, night vision tubes, OLED manufacturing, etc., to release enough alkali metals and alkaline earth metals to meet the needs of mass production.

This product provides a safe and effective means of coating ultra-pure alkali metals, keeping alkali metals pure in their stable salt form. Traditional strip AMD can release trace amounts (several milligrams) of alkali metals: including ultrapure vapor sources such as cesium, potassium, sodium, rubidium and lithium, our alkali metal strips are an ideal solution for the manufacture of polyalkali metal photocathodes.

Highlights of this product:

• High purity alkali metal film

• Controlled, repeatable alkali metal evaporation rates

• No particles falling

• No harmful gas is generated during alkali metal coating

• Various sizes: strips, boats

Terminal application:

• Photomultiplier tubes

• Night Vision Tube

• X-ray image intensifier


• Atomic clock

• Magneto-optical catcher
