Abstract

The invention provides devices for improving assay protocol compliance, reproducibility, and sensitivity. In particular, the devices of the present invention are tailored to certain single-cell sequencing assays, including single-cell RNA sequencing assays that utilize pre-templated instant partitions (PIPs) templates, wherein such devices hold tubes stationary while performing sample preparation, provide reproducible volume removal from tubes, allow for improved magnetic separation of analytes from buffers, and provide reproducible centrifugation of tubes.

Claims (22)

1 . A vortex adapter configured for use with a vortex mixer, said adapter comprising:

a base comprising a proximal portion releasably couplable to a hub of a vortex mixer; and

a tube holder releasably mounted to a distal portion of the base and comprising a plurality of apertures for receiving a plurality of tubes, respectively, wherein said tube holder is movable between a fixed first position in which the tube holder is releasably mounted to the distal portion of the base such that each of said apertures is oriented in a vertical direction relative to the base and a second fixed position in which the tube holder is releasably mounted to the distal portion of the base such that each of said apertures is oriented in a horizontal direction relative to the base.

2 . The vortex adapter of claim 1 , wherein each of the plurality of apertures is shaped and/or sized to retain a respective tube therein and configured to subject any tube therein to vortex forces from a vortex mixer.

3 . The vortex adapter of claim 2 , wherein the apertures are shaped and/or sized to receive and retain a tube comprising of volume of between 0.1 mL and 5 mL.

4 . The vortex adapter of claim 2 , wherein, when the tube holder is in the first position, each of the apertures retains a respective tube received therein in a vertical direction.

5 . The vortex adapter of claim 4 , wherein a longitudinal axis of each tube is orthogonal relative to a surface upon which a vortex mixer is placed.

6 . The vortex adapter of claim 4 , wherein, when the tube holder is in the first position, tubes received and retained within respective apertures are subjected to vertical vortexing upon receipt of vortex forces from the vortex mixer.

7 . The vortex adapter of claim 2 , wherein, when the tube holder is in the second position, each of the apertures retains a respective tube received therein in a horizontal direction.

8 . The vortex adapter of claim 7 , wherein a longitudinal axis of each tube is parallel relative to a surface upon which a vortex mixer is placed.

9 . The vortex adapter of claim 7 , wherein, when the tube holder is in the second position, tubes received and retained within respective apertures are subjected to horizontal vortexing upon receipt of vortex forces from the vortex mixer.

10 . The vortex adapter of claim 1 , wherein the tube holder comprises at least a first set of apertures arranged in a row.

11 . The vortex adapter of claim 10 , wherein the tube holder comprises a single set of apertures arranged in a row and provided on one side of the tube holder.

12 . The vortex adapter of claim 11 , wherein the tube holder comprises one or more counterweights provided on an opposing side of the tube holder for balancing inertial forces upon receipt of vortex forces from the vortex mixer.

13 . The vortex adapter of claim 10 , wherein the tube holder comprises two sets of apertures, each set arranged in a separate room and provided on opposing sides of the tube holder.

14 . The vortex adapter of claim 1 , further comprising a connection member provided at the distal portion of the base and selectively moveable between an engaged position and a disengaged position.

15 . The vortex adapter of claim 14 , wherein, when in the engaged position, the connection member maintains the tube holder in one of the first and second positions.

16 . The vortex adapter of claim 15 , wherein, when in the disengaged position, the tube holder is moveable between the first and second positions.

17 . The vortex adapter of claim 14 , wherein the distal portion of the base comprises two knuckle members defining a channel therebetween.

18 . The vortex adapter of claim 17 , wherein the connection member comprises an adjustable bolt assembly extending between the knuckle members and configured to draw the knuckle members together upon movement of the bolt assembly to the engaged position.

19 . The vortex adapter of claim 18 , wherein the tube holder comprises a body portion sized to fit within the channel in either of the first and second positions.

20 . The vortex adapter of claim 19 , wherein, when in the engaged position, the connection member causes the knuckle members to apply a retention force upon the body portion of the tube holder and prevent movement thereof within the channel.
