Special Glass 10 (Glass 0100, soda lime glass)
DESCRIPTION
Crystal Clear Special Glass 10 (Glass 0100, soda lime glass) 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. Glass capillaries have a wall thickness of 0.01 mm and an overall length of 80 mm +/-5 mm. Glass capillaries are available in a wide range of outside diameters from 0.1 mm to 2.0 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 u 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 u cm-1 for u CuK Radiation (Wavelength for Copper radiation is 1.5418 Angstrom) and 14.7 u 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 30 to 40 mm from the closed end (measuring instrument: LaserMicrometer LS 7500) The tolerances are as follows.
