Device for isolating living cells e.g. tumor cells on filter, comprises support attached to filter, compartment having upper and lower openings, unit movable with respect to the compartment for releasing the support, and removable nozzle

摘要

The device comprises a filter support (108) attached to a filter, a compartment (102) having an upper opening and a lower opening, a unit (110) movable with respect to the compartment for releasing the support, and a removable nozzle (104) tightly fixed and adapted to disallow the relative movement of the movable unit and the compartment which allows to apply the force and release the filter support. The nozzle has a lower opening that adapts to a depression chamber of a vacuum system. The filter support is present in the form of a washer, a coverslip object and an Eppendorf tube. The device comprises a filter support (108) attached to a filter, a compartment (102) having an upper opening and a lower opening, a unit (110) movable with respect to the compartment for releasing the support, and a removable nozzle (104) tightly fixed and adapted to disallow the relative movement of the movable unit and the compartment which allows to apply the force and release the filter support. The nozzle has a lower opening that adapts to a depression chamber of a vacuum system. The filter support is present in the form of a washer, a coverslip object and an Eppendorf tube, and has dimensions greater than or equal to coverslip object and has a thickness of = 0.3 mm. Upper and lower inner parts of the filter support are present in the form of upper and lower inner parts of the Eppendorf tube. The filter support is mechanically connected to the compartment and the movable unit for applying force. An independent claim is included for a process for isolating living cells on a filter.
