Double Layered Tubes
Double Layered NMR Tube for Toxic Samples
Wilmad’s Double Layered Tubes provide extra protection for your toxic sample. It can also be used with a reference standard which is insoluble in the sample or may cause a reaction. The Outer tube and inner tube have about a 50 μm gap and the system is ideal for variable temperature studies as the components are made of the same Type 1, Class A borosilicate glass. Each insert fits snugly into the outer tube like a syringe plunger fits its barrel.
