Filter domes are recommended for EPA-type sample digestions prior to atomic absorption spectroscopy.
- Constructed of non-metallic materials
- Filters quickly and simply, three times faster than the gravity method
- Filtrate is collected directly in a beaker, eliminating transfers
- Designed for direct filtration and for use where transfers should be avoided
- Valve and hose connections are made of CTFE
- O-rings are FKM
Filter domes are constructed of 33 expansion, low extractable borosilicate glass and polypropylene, virtually eliminating chances of trace metal contamination.
Several units may be connected in a series and vacuum applied from a single source. For rubber stopper size eight.
Certifications: Glass conforming to USP Type I and ASTM E438, Type I, Class A requirements.
