Abstract
Disclosed is a unit volume mixing apparatus for reconstituting a one or more component concentrated media in an influent stream. Mixing is facilitated by a water-driven mixing vortex. The effluent fluid stream is filtered, sterilized and delivered to a sterilized receiving bag for containing a unit volume of reconstituted material.
Claims7
A mixing apparatus for mixing a concentrated material with an incoming fluid stream, comprising:
- a housing having a substantially cylindrical first mixing chamber therein for containing concentrated material to be mixed;
- an influent port in the housing for providing fluid communication between the first mixing chamber and a source of fluid;
- and
- an effluent port in the housing, said effluent port having a filter for substantially preventing the escape of unmixed powdered material from the first mixing chamber;
- wherein the influent port is positioned to direct incoming fluid alone an axis which is generally tangential to the interior wall of the first mixing chamber thereby generating a rotational fluid velocity within the first mixing chamber upon introduction of the fluid under pressure.
A mixing apparatus for mixing a concentrated material with an incoming fluid stream, comprising:
- a housing having a substantially cylindrical first mixing chamber therein for containing concentrated material to be mixed;
- a second mixing chamber in fluid communication with the first mixing chamber, for containing a second concentrated material to be mixed with the incoming fluid stream;
- a filter in between the first and second mixing chambers, for permitting the passage of fluid therebetween but substantially preventing the passage of unmixed concentrated material;
- an influent port in the housing for providing fluid communication between the first mixing chamber and a source of fluid;
- and
- an effluent port in the housing and a sterilization unit downstream from and in fluid communication with said effluent port for sterilizing the concentrated material;
- wherein the only fluid permitted to enter the second mixing chamber is from the first mixing chamber;
- wherein the influent port is positioned to direct incoming fluid along an axis which is generally tangential to the interior wall of the first mixing chamber thereby generating a rotational fluid velocity within the first mixing chamber upon introduction of the fluid under pressure.
An apparatus for reconstituting powdered cell culture media, comprising:
- an elongate tubular housing having a first generally cylindrical mixing chamber therein;
- an influent port in the housing, for directing an influent fluid stream generally along a tangent to the interior cylindrical wall of the first mixing chamber;
- an effluent filter in the first mixing chamber;
- a second mixing chamber in the housing, in downstream fluid communication with the first mixing chamber by way of said effluent filter;
- an effluent port in the housing, in fluid communication with the influent port by way of the first and second mixing chambers;
- and
- a sterilization unit downstream from and in fluid communication with said second effluent port for sterilizing the reconstituted cell culture media;
- wherein the only fluid permitted to enter the second mixing chamber is from the first mixing chamber.
