Options

Name
Description
Hydrostatic press unit
Ideal hydraulic press and mold for creating rods from raw material.
Mass flow controller
Mass flow controllers enable the mixing of two kinds of gases when growing a single crystal.
Cold trap
This unit can be used to trap evaporated materials and reduce devitrification of the quartz tube, enabling the growth of a single crystal without loss of heating performance.
Use of this unit is extremely effective when evaporation of molten raw material is noticeable.

[Results]
Without the cold trap, it may be necessary to frequently adjust lamp power during crystal growth due to the eventual contamination of the quartz tube. The cold trap improves the stability of crystal-growth conditions by keeping the quartz tube clean.

The cold trap helps prolong quartz tube usage, which reduces running costs.
Example: Growth of single Sr2RuO4crystals
Without cold trap: Quartz tube was able to be used 4–5 times.
Using Cold trap: Quartz tube was able to be used more than 10 times.
Example: Growth of single Sr3Ru2O7crystals
Without cold trap: Quartz tube was able to be used 2–3 times.
Using Cold trap: Quartz tube was able to be used 8–9 times.
