The "Nipple NEG Pump" is a new type of NEG pump that has pill-shaped (φ10×t3) NEG materials affixed to the walls of the chamber like tiles. By placing a shroud shape in the dead space within the chamber, the system can quickly transform into an ultra-high vacuum environment. Additionally, it is easy to design for over 1000 L/s and can accommodate stainless steel vacuum chambers. 【Features】 ■ Vibration-free, power-free, and free from charged particle noise ■ Free design and installation direction ■ NEG: St707 type ZrVFe alloy ■ Stacked pill-shaped NEG within a double mesh ■ Easy generation of XHV below 10^-10 Pa *For more details, please refer to the PDF document or feel free to contact us.

The "Magic NEG Pump" is a new concept getter pump that extends its exhaust capability to the ultra-high vacuum (XHV) range. To minimize the hydrogen gas generated by the pump itself, we have restructured the pump's materials and design. By combining this product with auxiliary pumps such as turbo molecular pumps (open system) or small ion pumps (sealed system), it is possible to achieve XHV levels in the range of 10^-10 Pa within 24 hours from atmospheric pressure. 【Features】 ■ NEG is arranged on the walls of the pump casing ■ Ultra-low gas release pump casing made of 0.2% BeCu alloy ■ Effective exhaust speed extended to the 10^-10 Pa range ■ High exhaust speed for CO (comparable to H2) ■ Compatible with SUS ICF070 & 114 flanges *For more details, please refer to the PDF document or feel free to contact us.

The 'Magical Nipple' is an innovative product that utilizes the properties of our uniquely developed 0.2% BeCu alloy material. You can use it simply by inserting the head of a nude BA gauge or EX gauge into this product and attaching it to the chamber. When the gauge is surrounded by this product, the heat rays emitted from the filament will be reflected at a rate of 97% on the surface of the wall. [Features] ■ Gas release from the vacuum gauge is reduced to 1/7 ■ Achieved vacuum improves by about one digit ■ Power consumption is reduced to less than 1/2 ■ Made of 0.2% BeCu alloy (AlCu also available) ■ Copper surface is passivated *For more details, please refer to the PDF materials or feel free to contact us.
