Vacuum filtration apparatus |
摘要 |
A filtration apparatus provides for semiautomatic operation by including a filter element dispenser located at a filtration station. In order to effect removal of a used filter element from the filtration station, a tilting mechanism allows for tilting of a filtration stage which breaks or interrupts a vacuum which is otherwise continuously applied to the filtration station. In operation, the filter dispenser is manually rotated about a support to dispense a filter element in a filtration port at the filtration station. Next, a filtration cup which includes a filtration well is manually rotated about the support and positioned to be seated in the filtration port. After the filtration cup is seated in the filtration port a liquid to be filtered can be dispensed into the filtration well.
