Features
Quartz
Thin walled - 10 micron
Description
Crystal Clear Quartz capillaries that are extremely thin walled (approximately 10 micron wall thickness). The length of the capillary has a well defined diameter, with one end having a funnel shape and the other end closed. Quartz capillaries have a wall thickness of 0.01 mm and an overall length of 80 mm +/-5 mm. Quartz capillaries are available in a wide range of outside diameters from 0.1 mm to 5.0 mm. They are designed to mount, hold, and store small molecule and biological macromolecular crystals for x-ray data collection. Capillaries can also be used for crystal density measurements and crystal growth experiments. The capillaries can be sealed tightly against moisture and gases using wax, epoxy, or other sealing materials.

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 2.5 mm capillaries the open end capillary tube base size is 3.0 +/- 0.2 mm OD x 0.2 +/- 0.15 mm Wall thickness. For 3.0 and 3.5 mm capillaries the open end capillary base size is about 4.4 mm OD x 0.25 mm Wall thickness. For 4.0 and 5.0 mm capillaries the open end capillary based size is about 6.0 x 0.25 mm.

Quartz has a Linear Absorption Coefficient of 75.8 µ cm-1 for µ CuK Radiation (Wavelength for Copper radiation is 1.5418 Angstrom) and 8.2 µ cm-1 MoK Radiation (Wavelength for Molybdenum radiation is 0.7107 Angstrom) and a softening temperature of 1,730 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

0.5 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
2.5 mm -0.250 / +0.250 mm
3.0 mm -0.250 / +0.250 mm
4.0 mm -0.500 / +0.500 mm
5.0 mm -0.500 / +0.500 mm
