NOTE: Part numbers may change.
Consult LECO for latest information.
Please Note: Quartz Tubes are typically utilized for higher
temperature applications (i.e. catalyst tubes). Glass reagent/filter tubes
are designed for lower temperature applications. Glass tubes should
not be used in place of quartz tubes.
