Impurity Analyses – Clear Fused Quartz (CFQ) vs. Suprasil (Synthetic Quartz)
Clear Fused Quartz (CFQ) is purified from naturally occurring quartz so the existence of certain material radicals from mining is inevitable. Chemical impurity analysis results for CFQ are shown below:

Variable Temperature Accessories
Replacement Parts for VT Systems

Need a replacement component for your variable temperature system?
Since Wilmad offers VT replacement components at prices significantly lower than the Original Equipment Manufacturer (OEM), why pay more? Wilmad components are equivalent or, in some cases, better in quality than you get from your EPR Spectrometer manufacturer.
