LT3-WMX-1SS.png

The LT3-WMX-1SS offers a wide range of flexibility at a reasonable cost.

This high performance system offers an all stainless steel constructed vacuum shroud along with a welded stainless steel instrumentation skirt. This system is capable of achieving vacuum levels of 10-7 Torr with an appropriate vacuum system. The nickel plated copper radiation shield provides low emissivity which is ideal for low temperature experiments.
