Product Overview
Transferring liquids and solids is a common working method. In this activity the funnel is used, which due to its shape can absorb a relatively large amount of liquid or solid and transfer it through a constriction into a vessel with a small opening. Funnels are available in different sizes and designs, selected according to their application.
Specifications
| Diameter d (mm) | 55 |
| 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. |
