ABSTRACT:
This invention relates generally to laboratory glassware apparatus and particularly to laboratory apparatus and kits thereof. Disclosed apparatus is used to extract and/or concentrate specific substances for analytical purposes from sample liquids by passing a predetermined solvent through the sample. The invention includes a modular sample container body for holding a sample to be processed. The container body has a variety of disconnect joints for receiving a variety of disconnectable attachments that are used in the extraction and/or concentration process of the specific substance. The invention also includes a universal modular container body having a variety of disconnect joints that may be used with solvents having a density lesser or greater than the density of the sample liquid being processed. An in-line drying adaptor is disclosed which allows for a drying step to be included within the processing of the sample thereby precluding the need to transfer the sample from the disclosed apparatus to a separate drying apparatus.
