Product Overview
These dropping cylinders are ideal for the measured addition of solutions, reagents and/or chemicals to a reaction mixture. The double graduated scale shows the approximate volume of liquid contained in the funnel or the volume dispensed from the funnel. This design features a ground cone joint on the lower end, which allows an accurate connection to other ground jointed items e.g. multi-neck flasks.
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. |
