Abstract
A mold is configured to form a gel monolith including a first gel portion and a second gel portion. The mold includes a base including a first hydrophobic surface. The mold further includes a tubular outer wall including a second hydrophobic surface, and the outer wall is coupled to the base. The mold further includes a removable tubular insert including an inner surface and an outer hydrophobic surface. The insert is removably coupled to the base.
Claims26
A mold for forming a gel monolith comprising a first gel portion and a second gel portion, the mold comprising:
- a base comprising a first hydrophobic surface;
- a tubular outer wall comprising a second hydrophobic surface, the outer wall coupled to the base;
- a removable tubular insert comprising an inner surface and an outer hydrophobic surface, the insert removably coupled to the base;
- and
- a plug removably coupled to the tubular insert, thereby forming an airtight seal between the plug and the tubular insert.
A mold for forming a gel monolith comprising a first gel portion and a second gel portion, the mold comprising:
- a base comprising a first hydrophobic surface;
- a tubular outer wall comprising a second hydrophobic surface, the outer wall coupled to the base;
- and
- a removable tubular insert comprising an inner surface and an outer hydrophobic surface, the insert removably coupled to the base, wherein the base further comprises:
- a first base portion coupled to the outer wall, the first base portion comprising the first hydrophobic surface, a cavity, and a mating surface, the cavity extending from the first hydrophobic surface to the mating surface;
- a second base portion comprising a tubular projection adapted to couple to the insert, the second base portion adapted to couple to the mating surface with the tubular projection coupled to the cavity;
- and
- a third base portion comprising a solid projection, the third base portion adapted to couple to the mating surface with the solid projection filling the cavity, wherein the second and third base portions are interchangeably removably coupled to the first base portion.
A mold for forming a gel monolith comprising a first gel portion and a second gel portion, the mold comprising:
- a base comprising a first hydrophobic surface;
- a tubular outer wall comprising a second hydrophobic surface, the outer wall coupled to the base;
- a removable tubular insert comprising an inner surface and an outer hydrophobic surface, the insert removably coupled to the base;
- and
- a cap removably coupled to the outer wall and the insert, the cap having a third hydrophobic surface.
A mold for forming a gel monolith comprising a first gel portion and a second gel portion, the mold comprising:
- a base comprising a first hydrophobic surface;
- a tubular outer wall comprising a second hydrophobic surface, the outer wall coupled to the base;
- and
- a removable tubular insert comprising an inner surface and an outer hydrophobic surface, the insert removably coupled to the base, wherein the base further comprises:
- a mating surface with a first seal, whereby the mating surface is removably coupled to the outer wall and the first seal forms a liquid-tight seal between the base and the outer wall;
- a cavity removably coupled to the insert;
- a recess;
- a removable second seal between the cavity and the recess, the second seal forming a removable liquid-tight seal between the cavity and the recess;
- and
- a plug removably coupled to the recess, whereby removing the plug and second seal from the recess fluidly couples the cavity and the recess.
A mold for forming a gel monolith comprising a first gel portion and a second gel portion, the mold comprising:
- a base comprising a first hydrophobic surface;
- a tubular outer wall comprising a second hydrophobic surface, the outer wall coupled to the base;
- and
- a removable tubular insert comprising an inner surface and an outer hydrophobic surface, the insert removably coupled to the base, wherein the base further comprises:
- a bottom wall which encloses one end of the outer wall;
- and
- a plug removably coupled to the bottom wall, whereby the plug forms a removable liquid-tight seal between the plug and the bottom wall.
A mold for forming a gel monolith comprising a first gel portion and a second gel portion, the mold comprising:
- a base comprising a first hydrophobic surface;
- a tubular outer wall comprising a second hydrophobic surface, the outer wall coupled to the base;
- and
- an insert removably coupled to the base, the insert comprising:
- a first portion removably coupled to the base;
- a second portion spaced from the base;
- an outer hydrophobic surface;
- and
- an inner surface defining a conduit which fluidly couples the first portion and the second;
- and
- a plug removably coupled to the tubular insert, thereby forming an airtight seal between the plug and the tubular insert.
