Product Overview
These flat flange lids are used in conjunction with flat flange vessels as an alternative to the large volume round flasks. The wide neck opening of flat flange vessels allows easy access to the vessel contents. The two parts are held together by means of a clamping ring. The multi-neck ground necks on these lids allow the connection of a variety of other ground joint components such as dropping funnels, condensers and stirring shafts. Flat flange vessels are well suited for preparative work such as general reactions, distillations, evaporation and drying of solid and viscous substances. Their heavy wall construction and geometry make these vessels safe for working under positive pressure and vacuum.
Specifications
| Boro 3.3 | Borosilicate glass 3.3 has a very good chemical resistance, virtual inert behavior, a high maximum usage temperature, high light transparency and minimal thermal expansion. Borosilicate glass 3.3 has a linear coefficient of expansion of 3.3 Ć 10ā6 Kā1 at 20 Ā°C. It also conforms to the requirements of a USP/EP/JP Type 1 neutral glass suitable for use by the pharmaceutical industry. The properties of DURANĀ® are specified to ISO 3585 and ASTM-E438 Type 1 Class A. |
