In one embodiment, a contiguous, elastic cover, for a dissolution-testing vessel, has a slit from a central opening to its outer edge. The cover may be placed around a stirring shaft by deforming the elastic cover to temporarily enlarge the slit. After returning to its original shape, the cover is placed over the vessel with the shaft free to rotate unimpeded within the central opening. The cover has a first raised annular disk on one side and a second raised annular disk on the other side, where the disks have different outer diameters to enable the cover to be used with differently sized vessels. The cover has a first opening having a first diameter and a second opening having a different, second diameter such that a conventional probe fits either at one depth within the first opening or at a different, second depth within the second opening.

1. A vessel cover for dissolution-testing equipment comprising a vessel and a stirring shaft, wherein: the vessel cover is made of an elastic material;the vessel cover has an original shape having an outer circumference;the vessel cover defines a central opening having a diameter larger than the diameter of the stirring shaft;the vessel cover comprises a slit running from the central opening to the outer circumference, wherein, when the vessel cover is in the original shape, the slit has a width smaller than the diameter of the stirring shaft; andthe vessel cover is adapted to be temporarily deformed and then return to substantially the original shape, wherein the temporary deformation widens the slit such that the stifling shaft is allowed to pass through the temporarily widened slit and into the central opening. 2. The vessel cover of claim 1, wherein the vessel cover has a notch at the end of the slit at the outer circumference of the vessel cover. 3. The vessel cover of claim 2, wherein the opening of the notch is larger than the diameter of the stifling shaft. 4. The vessel cover of claim 1, wherein the elastic material is silicone. 5. The vessel cover of claim 1, wherein: the vessel cover comprises a first side and a second side;the first side comprises a first annular disk that is (i) a raised feature concentric with the central opening and (ii) split by the slit; andthe outer diameter of the first annular disk is designed to fit a first vessel-setup type. 6. The vessel cover of claim 5, wherein the second side comprises a first label identifying the first vessel-setup type. 7. The vessel cover of claim 5, wherein: the second side comprises a second annular disk that is (i) a raised feature concentric with the central opening and (ii) split by the slit; andthe outer diameter of the second annular disk is: different from the outer diameter of the first annular disk; anddesigned to fit a second vessel-setup type different from the first vessel-setup type. 8. The vessel cover of claim 7, wherein the first side comprises a second label identifying the second vessel-setup type. 9. The vessel cover of claim 5, wherein: the first side further comprises a third annular disk that is (i) a raised feature above the first annular disk, (ii) concentric with the central opening and split by the slit; andthe outer diameter of the third annular disk is designed to fit a third vessel-setup type different from the first vessel-setup type. 10. The vessel cover of claim 1, wherein: the dissolution testing equipment further comprises a probe;the probe comprises: a cannula having a cannula diameter and an inlet;a hub connected to the cannula and having a hub diameter larger than the cannula diameter; anda barrel connected to the hub and having a barrel diameter larger than the hub diameter;the vessel cover further comprises: a first peripheral opening having a diameter that is both larger than the cannula diameter and sufficiently smaller than the hub diameter to prevent entry of the hub into the first peripheral opening, such that inserting the probe in the first peripheral opening results in a first penetration depth for the inlet; anda second peripheral opening having a diameter that is both larger than the hub diameter and sufficiently smaller than the barrel diameter to prevent entry of the barrel into the second peripheral opening, such that inserting the probe in the second peripheral opening results in a second penetration depth for the inlet different from the first penetration depth. 11. The vessel cover of claim 10, wherein: the vessel cover comprises a first side and a second side;the first side comprises a first annular disk that is (i) a raised feature concentric with the central opening and (ii) split by the slit;the second side comprises a second annular disk that is (i) a raised feature concentric with the central opening and (ii) split by the slit;the first peripheral opening is located within a first circular recess in the first annular disk and a second circular recess in the second annular disk; andthe diameters of the first and second circular recesses are each larger than the hub diameter. 12. The vessel cover of claim 10, wherein the vessel cover further comprises: a first plug for selectively plugging the second peripheral opening, the first plug comprising a central portion having substantially the same cross section as the second peripheral opening; anda first-tail opening that (i) is connected to the second peripheral opening and (ii) houses a first tail connected between the central portion of the first plug and a wall of the first-tail opening so that the first plug may swing in and out of the second peripheral opening, with the first tail swinging correspondingly within the first-tail opening, so that the first plug selectively plugs or unplugs the second peripheral opening. 13. The vessel cover of claim 12, wherein the vessel cover further comprises: a third peripheral opening substantially similar to the second peripheral opening;a second plug for selectively plugging the third peripheral opening, the second plug comprising a central portion having substantially the same cross section as the third peripheral opening; anda second-tail opening that (i) is connected to the third peripheral opening and (ii) houses a second tail connected between the central portion of the second plug and a wall of the second-tail opening so that the second plug may swing in and out of the second peripheral opening, with the second tail swinging within the second-tail opening, so that the second plug selectively plugs or unplugs the third peripheral opening. 14. The vessel cover of claim 13, wherein the vessel cover is a contiguous vessel cover having unitary construction. 15. The vessel cover of claim 12, wherein the first tail and first-tail opening correspond to an arc of a circle concentric with the central opening of the vessel cover. 16. The vessel cover of claim 12, wherein: there is sufficient static friction between the first plug and the inside of the second peripheral opening to keep the first plug from swinging out of the second peripheral opening due to the force of gravity;the static friction is not sufficient to prevent a user from forcing the first plug out of the second peripheral opening. 17. The vessel cover of claim 12, wherein the first plug further comprises first and second pull tabs connected to the top and bottom, respectively, of the central portion of the first plug, the first and second pull tabs adapted to be used to pull the first plug out of the second peripheral opening from corresponding sides of the vessel cover. 18. The vessel cover of claim 10, wherein the vessel cover further comprises a plurality of additional slits radiating from the central opening that do not extend to the outer circumference of the vessel cover. 19. The vessel cover of claim 10, wherein the second peripheral opening comprises integral flaps adapted to: substantially occlude the second peripheral opening;flex out of the way of the probe to allow the insertion of the probe hub; andreturn to substantially occluding the second peripheral opening upon removal of the probe hub. 20. The vessel cover of claim 1, wherein: the dissolution-testing equipment further comprises a substantially cylindrical basket adapted to attach to the stifling shaft;the outside diameter of the basket is larger than the diameter of the stirring shaft;the diameter of the central opening is larger than the outside diameter of the basket; andthe dissolution-testing equipment further comprises a cap plug positioned around the stifling shaft and adapted to selectively plug the central opening. 21. The vessel cover of claim 1, wherein the vessel cover is a contiguous vessel cover having unitary construction.
