Double the writing area allows for easy sample marking and identification.

• 2× larger marking area eliminates cramped and unreadable sample names
• Silk screened writing area keeps sample names from easily wiping off
• Designed for routine use in most low to mid field NMR spectrometers
• Camber and concentricity values listed are the Total Indicator Reading (TIR)
• Made from ASTM E438 Type 1 Class B glass
• 100% inspected for surface defects and physical dimensions

These high throughput tubes have an average camber of 60 µm to ensure spectrum clarity for small molecule (MW<250) samples up to 600 MHz.
