GL45 Thread Holder - Griffin Glass Tools
Thread holding Tool to hold GL style glass threads. The thread holding portion of this tool is made from a super high grade ultra dense graphite and the tube handle is stainless steel. We have put the tubes through a straightening die in order to assure handle straightness. The ultra high density graphite is absolutely the best material to come into direct contact with the glass threads in order to avoid stress to the thread blank. We have put the graphite through rigorous testing in order to assure longevity of this holding tool. These thread holders are a great solution to holding the threads that will become the cap/ top of a flask or other vessel.
