Borosilicate glass, Class A, ASTM Type 1.

  • 100% inspection with multiple NIST traceable gauges and optical surface defect checks
  • To maximise SNR, Precision NMR tubes have minimal paramagnetic impurities that would impact shimming
  • Tight ID and OD tolerance as small as 0,0065 mm accommodates inserts
  • Caps are not recommended for use with samples dissolved in chloroform-d or acetone-d6

NMR PRECISION tubes are manufactured from borosilicate glass that meets the requirement of Type 1 Class A glass from ASTM E438. PRECISION tube has 3 fold less paramagnetic contamination comparing to the ECONOMY tube, and can be operated safely at temperature up to 230 ˚C, and within a temperature step of 120 ˚C. PRECISION tube is rated as hydrolytic class 1, which states that the inner surface is resistant to strong acid and base at ambient temperature. These tubes are ideal for experiments requiring critical shimming quality (high/ultrahigh field, non-spinning, multi-dimensional, multi-nuclei, DNP experiments and studies involving biological samples).
