Special Glass 10 Capillaries

In determining what glass or quartz capillary is right for you, please refer to the “Linear Absorption Coefficient µ cm-1” table. This table indicates the amount of radiation that is absorbed by the capillary during x-ray data collection. 

For 0.1 mm to 2.0 mm capillaries the open end capillary tube base size is 3.0 +/- 0.15 mm OD x 0.2 +/- 0.10 mm Wall thickness. 

Special Glass 10 has a Linear Absorption Coefficient of 126.0 µ cm-1 for µ CuK Radiation (Wavelength for Copper radiation is 1.5418 Angstrom) and 14.7 µ cm-1 MoK Radiation (Wavelength for Molybdenum radiation is 0.7107 Angstrom) and a softening temperature of 815 degrees Celsius. 

The Diameter is measured about 40 mm from the closed end. The tolerances are as follows. 

0.1 mm -0.075 / +0.075 mm 
0.2 mm -0.050 / +0.050 mm 
0.3 mm -0.050 / +0.100 mm 
0.4 mm -0.100 / +0.100 mm 
0.5 mm -0.100 / +0.100 mm 
0.6 mm -0.100 / +0.100 mm 
0.7 mm -0.150 / +0.150 mm 
0.8 mm -0.150 / +0.150 mm 
0.9 mm -0.150 / +0.150 mm 
1.0 mm -0.150 / +0.250 mm 
1.5 mm -0.250 / +0.250 mm 
2.0 mm -0.250 / +0.250 mm
