1. A closure for attachment to a sample container configured for use in a centrifuge, the closure comprising: a top wall;an annular skirt wall depending from the top wall and defining a maximum outer diameter, the annular skirt wall having a threaded inner surface configured to engage a container body; anda handle extending from the top wall and formed integrally with the top wall and the annular skirt wall, the handle including a central boss and at least two circumferentially spaced finger grips extending radially outward from the central boss,wherein the at least two finger grips are axially offset from the top wall of the closure such that an axial space is defined between the top wall of the closure and a respective underside of each of the at least two finger grips at least at respective free terminal ends thereof, the finger grips and axial spaces being configured to enable grasping of the handle to facilitate lifting of the closure and sample container,and further wherein the respective free terminal end of each of the finger grips is located so as not to extend beyond the maximum outer diameter. 2. The closure of claim 1, wherein the central boss extends along an axial centerline of the closure. 3. The closure of claim 2, wherein the central boss includes an upper portion and the at least two finger grips extend radially outward from the upper portion. 4. The closure of claim 1, wherein the handle includes first and second diametrically opposed finger grips. 5. The closure of claim 3, wherein the handle includes first and second diametrically opposed finger grips. 6. The closure of claim 1, wherein the central boss includes a generally circular cross-sectional shape. 7. The closure of claim 1, wherein the closure further comprises a sealing member located in an inner pocket defined by the top wall and the skirt wall of the closure. 8. The closure of claim 7, wherein the handle is hollow and defines a recess, and further wherein the sealing member includes a central boss received in the recess of the handle. 9. A sample container for use in a centrifuge, comprising: a container body having an inner cavity, a mouth opening to the inner cavity, and a threaded outer surface located below the mouth opening; anda closure removably attachable to the container body for closing the mouth when the closure is attached to the container body, the closure including: a top wall;an annular skirt wall depending from the top wall and defining a maximum outer diameter, the annular skirt wall having a threaded inner surface configured to engage the threaded outer surface of the container body; anda handle extending from the top wall and formed integrally with the top wall and the annular skirt wall, the handle including a central boss and at least two circumferentially spaced finger grips extending radially outward from the central boss,wherein the at least two finger grips are axially offset from the top wall of the closure such that an axial space is defined between the top wall of the closure and a respective underside of each of the at least two finger grips at least at respective free terminal ends thereof, the finger grips and axial spaces being configured to enable grasping of the handle to facilitate lifting of the closure and sample container,and further wherein the respective free terminal end of each of the finger grips is located so as not to extend beyond the maximum outer diameter. 10. The sample container of claim 9, wherein the central boss extends along an axial centerline of the closure. 11. The sample container of claim 10, wherein the central boss includes an upper portion and the at least two finger grips extend radially outward from the upper portion. 12. The sample container of claim 9, wherein the handle includes first and second diametrically opposed finger grips. 13. The sample container of claim 9, wherein the closure further includes a sealing element located in an inner pocket defined by the top wall and the skirt wall of the closure. 14. The sample container of claim 13, wherein the handle is hollow and defines a recess, and further wherein the sealing member includes a central boss received in the recess of the handle. 15. The sample container of claim 9, wherein the container body includes a first threaded portion adjacent to the mouth, and the skirt wall of the enclosure includes a second threaded portion configured to threadedly engage the first threaded portion when the closure is attached to the container body and the handle is rotated. 16. The sample container of claim 9, wherein the sample container comprises a centrifuge bottle.
