“…In our approach, we avoid the previous problem of pulling apart the capillary with subsequent possible formation of pinhole defects. To remove the additional problem of localized heating effects, we have mounted a Stainless Steel guard around and underneath the heating element, this procedure greatly reduces undesired heating (or a thermal gradient) along the remainder of the capillary and thereby ensures crystal integrity (4).…”

There are numerous occasions when working in either an anaerobic recirculating dry box, a glove bag, or, alternatively, with a microscope that it is not possible or indeed desirable to use a naked flame to seal thin-walled glass capillaries containing crystals for X-ray crystallography. Previous workers have used a simple heating element attached to an electrical cord, with the temperature controlled by an external Variac (1). We have now explored this procedure in some detail, due to persistent problems with desolvating air/moisture-sensitive crystals. This sen-

“…The filling of thin-walled glass capillaries is tedious and time consuming especially when the powder tends to agglomerate due to extremely fine grinding (<10 t~m) in a micronizing mill. While special devices have been designed for loading capillaries in a dry box (Larsen & Leddy, 1958;Lange & Haendler, 1972), a technique greatly facilitating routine loading is currently in use in our laboratory. It involves placing the capillary in a nearly upright position in a 50 ml Erlenmeyer flask filled with water.…”

“…Alternatively, we have found that the Prentice-Hall model kits (Lange & Haendler, 1972) are also useful because of the internal ridges running the length of the tubing, which support the X-ray capillary tube while the glue sets. After ca 3-4 h the araldite has cured and the X-ray capillary tube may be handled in the atmosphere for several weeks with no visible decomposition of the crystals.…”
