CRYOGENICS DEWARS |
|
| Dewar flasks for cryogenic research have a long history at H. S. Martin. More than fifty years of experience in design and production have made H. S. Martin the most sought after name in dewars today. Our widely diversified selection answers most research needs. Procedures used in silvering of all Martin dewars meet or exceed those of the Bureau of Standards Journal of Research. The same procedures are used on all H. S. Martin vacuum-jacketed products. Standard dewar flasks are made of borosilicate glass (Pyrex® 7440 or Kimax ®KG33) available completely silvered or strip-silvered, and equipped with an aluminum base. Where space requirements or weight tolerances are critical, special wall thicknesses can be used. |  |
