TMA Quartz Sample Holder Thermomechanical Analyzer Dilatometry Lab Accessory

TMA Quartz Sample Holder Thermomechanical Analyzer Dilatometry Lab Accessory

This is a quartz glass sample holder assembly designed for use with thermomechanical analyzers (TMA). The assembly consists of a clear quartz glass tube, a stainless steel base cylinder, a mid-tube sensor or clamp module, and attached lead wires with a multi-pin circular connector. Quartz is the standard material for TMA sample holders due to its extremely low and well-characterized coefficient of thermal expansion, making it a near-zero-expansion reference baseline for accurate dimensional measurements of the sample under test.

Specifications & What's Included

• Connector: Multi-pin circular connector on red lead wire
• Mid-tube module: Small black clamp/sensor module visible on glass tube
• Top: Fine sensor or thermocouple wire exiting top of quartz tube
• Condition: New from manufacturer — open box, possible long-term storage
• No brand or model markings legible on the assembly

Applications

Thermomechanical analyzers measure dimensional changes in materials — expansion, contraction, softening, and creep — as a function of temperature and applied load. TMA quartz sample holders are used across a wide range of thermal analysis applications including polymer characterization, thin film and coating analysis, composite material testing, glass transition studies, and ceramic or metal dilatometry. The quartz tube serves as the sample enclosure or probe guide within the TMA furnace, and its near-zero expansion properties ensure that measured dimensional changes reflect the sample alone rather than the holder. TMA instruments from manufacturers such as TA Instruments, Perkin-PerkinElmer, Mettler-Toledo, Netzsch, and Shimadzu all rely on quartz sample holders of this general design. These accessories are consumable or semi-consumable lab items that are replaced periodically, and lab-surplus new stock of this type is commonly sought by researchers and analytical labs maintaining or re-commissioning TMA systems.
