Quartz Capillaries
Applications
- X-ray data collection
- Liquid-liquid diffusion crystallization
- Gel acupuncture crystallization
Features
- Thin walled – 10 micron
- Quartz Glass 0620
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.
The Diameter is measured about 30 to 40 mm from the closed end (measuring instrument: LaserMicrometer LS 7500) The tolerances are as follows.
Diameter Tolerance Minimum Diameter Maximum Diameter
0.1 mm +/-0.05 mm 0.05 mm 0.15 mm

Capillary Cutting Stone™
Applications
- The easiest way to cut capillaries
Features
- Score and snap.
- Ceramic cutting stone
Description
These small (25 mm x 25 mm x 0.65 mm) cutting stones are used to make clean cuts of glass and quartz capillaries. Use the edge of the stone to etch the capillary then gently snap the capillary in two. This is useful for cutting the tips off closed capillaries used for mounting single crystals for x-ray diffraction analysis or for cutting capillaries to the desired length.
Capillary Cutting Procedure
1. Gently place the capillary on a clean, flat surface.
2. Gently holding the stone at approximately 30° angle to the capillary tube, starting near one edge of the stone, proceeding in a single, smooth motion, draw the length of the non-serrated edge of the stone across the capillary one time . Apply just enough pressure to score the capillary, do not attempt to cut through the capillary.
3. Pull the capillary axially until it breaks. If it won’t break, the score was not deep enough. Repeat the above steps, pressing down with slightly more force while drawing the cleaving stone the capillary.
4. Once cut, inspect the end finish to ensure the cut quality meets the application requirements.

StockOptions Sodium Acetate Buffer Kit
Applications
- Focused, titrated buffer stocks for crystal screening, optimization, & production
Features
- 0.1 unit increments for fine tuning pH
- pH 3.6 – 5.6
- 1.0 M concentrated stocks
- pKa = 4.8
Description
StockOptions Buffer kits are reagent toolboxes for the macromolecular crystal grower. Stock-Options reagent kits offer precisely formulated, high quality crystallization grade reagent stocks in convenient, cost-effective kits. The chemicals utilized in StockOptions kits are the same crystallization grade, ultra-high purity chemicals utilized in the Hampton Research kits. StockOptions reagents are carefully formulated under strict quality standards to ensure reliable performance and lot-to-lot consistency.
Preformulated stocks remove calculation, measurement, and formulation errors. No more second guessing how the reagent was formulated, what specific chemical was used, when it was made, or how to precisely reproduce that reagent when it is gone and more reagent is required for additional setups.
Each HR2-233 contains 21 unique reagents covering the pH range of 3.6 to 5.6 in 0.1 pH increments. Each reagent is supplied in a 10 milliliter volume and is titrated using HCl.
