Lab rack rotator and methods thereof
View Patent ↗A lab rack rotator includes a motor coupled to a shaft arranged to rotate in at least one direction in response to the motor. One or more mounts are located along the surface of the shaft and are configured to receive a lab sample rack which holds a plurality of lab samples contained in lab sample containers such as test tubes. Rotation of the shaft permits inversion of the plurality of lab samples, for instance whole blood samples. The lab rack rotator increases the number of lab samples that may be agitated in an automated process while decreasing the amount of time required for necessary pre-testing agitation of samples.
1. A lab sample rack rotator comprising:
a motor coupled to a shaft, the shaft arranged to rotate in at least one direction in response to the motor; and
one or more mounts along the shaft, the one or more mounts configured to receive a lab sample rack configured to hold a plurality of lab sample containers and comprising:
an open end,
a spring loaded-adjustable sidewall wherein the spring loaded-adjustable sidewall is configured to limit movement of the plurality of samples in the received sample rack and comprises a lockable securing system,
one or more fasteners to secure the open end of the one or more mounts, and
a stop device opposite the open end and arranged to securely locate the lab sample rack in the one or more mounts,
wherein rotation of the shaft permits inversion of the plurality of lab sample containers, and
wherein the one or more mounts provide a secure fit for the lab sample rack based on the longest dimension of the lab sample containers.
2. The lab sample rack rotator of claim 1 wherein the plurality of lab samples in the lab sample rack are maintained in a direction perpendicular to a length of the shaft.
3. The lab sample rack rotator of claim 1 wherein eight or more mounts are along the shaft.
4. The lab sample rack rotator of claim 3 wherein at least seven mounts are configured to receive the lab sample rack without reorientation of the shaft.
5. The lab sample rack rotator of claim 1 wherein the motor rotates the shaft at a rate of at least 10 rotations per minute.
6. The lab sample rack rotator of claim 1 wherein the one or more mounts are disposed on a surface of the shaft.
7. The lab sample rack rotator of claim 6 wherein the one or more mounts are removably attached to the shaft.
8. The lab sample rack rotator of claim 1 wherein the one or more mounts are voids in a body portion of the shaft.
9. The lab sample rack rotator of claim 1 wherein the spring loaded-adjustable sidewall is configured to provide a force in the direction of the sidewall opposite the adjustable sidewall.
10. The lab sample rack rotator of claim 1 wherein the spring loaded-adjustable sidewall spans the length of said mount.
