Abstract
The disclosure relates to a container for filtering a suspension which comprises a lid and a vessel. The container comprises a filter that divides an interior space of the container into a first compartment and a second compartment. The lid comprises a first access and a second access. The first access is connected to the first compartment, and the second access is connected to the second compartment.
Claims17
A container for filtering a suspension, the container comprising:
- a substantially cylindrical shaped vessel, divided into first and second compartments separated from each other by a liquid-permeable filter through which liquid can permeate between the first and second compartments, wherein the vessel has a height that is larger than a horizontal cross-section of the vessel;
- and
- a lid, defining a top side of the vessel , the lid comprising:
- a first septum over the first compartment, made of a material that is soft enough to be actuated open and closed automatically by respective insertion and withdrawal of a straight rigid first needle in a first direction providing a completely straight and unobstructed linear first access pathway into the first compartment;
- a second septum over the second compartment, made of a material that is soft enough to be actuated open and closed automatically by respective insertion and withdrawal of a straight rigid second needle in a second direction providing a completely straight and unobstructed linear second access pathway into the second compartment;
- and
- a laterally-oriented rotational alignment positioning feature, wherein the laterally-oriented rotational alignment positioning feature aligns the first access pathway with the first compartment and aligns the second access pathway with the second compartment and is further configured to guide the container in a defined alignment into a holder, and wherein the laterally-oriented rotational alignment positioning feature is designed in the form of a laterally outwardly directed extension of the lid configured to engage in a groove provided on the holder or in the form of a groove on the lid configured to receive an extension provided on the holder, wherein the outwardly directed extension of the lid or the extension provided on the holder is a lateral pin.

A method for filtering a suspension, comprising:
- providing or obtaining a container, the container comprising a substantially cylindrical shaped vessel divided into a first compartment and a second compartment, wherein the first compartment and the second compartment are separated laterally from each other by a liquid-permeable filter through which liquid can permeate between the first and second compartments, wherein the vessel has a height that is larger than a horizontal cross-section of the vessel;
- providing or obtaining a lid, defining a top side of the vessel the lid comprising:
- a first septum over the first compartment, made of a material that is soft enough to be actuated open and closed automatically by respective insertion and withdrawal of a straight rigid first needle in a first direction providing a completely straight and unobstructed linear first access pathway into the first compartment;
- a second septum over the second compartment, made of a material that is soft enough to be actuated open and closed automatically by respective insertion and withdrawal of a straight rigid second needle in a second direction providing a completely straight and unobstructed linear second access pathway into the second compartment;
- and
- a laterally-oriented rotational alignment positioning feature, wherein the laterally-oriented rotational alignment positioning feature aligns the first access pathway with the first compartment and aligns the second access pathway with the second compartment and is further configured to guide the container in a defined alignment into a holder, and wherein the laterally-oriented rotational alignment positioning feature is designed in the form of a laterally outwardly directed extension of the lid configured to engage in a groove provided on the holder or in the form of a groove on the lid configured to receive an extension provided on the holder, wherein the outwardly directed extension of the lid or the extension provided on the holder is a lateral pin;
- inserting a needle into the first septum in the first direction to introduce a fluid into the first compartment;
- and
- inserting a needle into the second septum in the second direction to withdraw a fluid from the second compartment.

A system for filtering a suspension, the system comprising:
- a holder;
- and
- a container, the container comprising:
- a substantially cylindrically shaped vessel, divided into a first compartment and a second compartment separated from each other by a liquid-permeable filter through which liquid can permeate between the first compartment and the second compartment, wherein the vessel has a height that is larger than a horizontal cross-section of the vessel;
- and
- a lid defining a top side of the vessel, the lid comprising:
- a first septum over the first compartment, made of a material that is soft enough to be actuated open and closed automatically by respective insertion and withdrawal of a straight rigid first needle in a first direction providing a completely straight and unobstructed linear first access pathway into the first compartment;
- a second septum over the second compartment, made of a material that is soft enough to be actuated open and closed automatically by respective insertion and withdrawal of a straight rigid second needle in a second direction providing a completely straight and unobstructed linear second access pathway into the second compartment;
- and
- a laterally-oriented rotational alignment positioning feature, wherein the laterally-oriented rotational alignment positioning feature aligns the first access pathway with the first compartment and aligns the second access pathway with the second compartment and is further configured to guide the container in a defined alignment into the holder, and wherein the laterally-oriented rotational alignment positioning feature is designed in the form of a laterally outwardly directed extension of the lid configured to engage in a groove provided on the holder or in the form of a groove on the lid configured to receive an extension provided on the holder, wherein the outwardly directed extension of the lid or the extension provided on the holder is a lateral pin.
