Head for a mixing apparatus
A head that can be coupled with a mixing apparatus includes a body that defines a longitudinal axis and includes a first side, a second side, a third side, and a fourth side. Each of the sides includes a projection. The body is configured to receive a microplate between the sides, which is removably secured to the body by the projections. At least one vertical channel in the body is configured to removably secure a first test tube to the body so that the longitudinal axis of the tube is perpendicular to the longitudinal axis of the body. The first vertical channel has a first diameter. At least one horizontal channel in the body is configured to removably secure a second test tube so that the longitudinal axis of the tube is parallel to the longitudinal axis of the body. The first test tube and the second test tube can be coupled to the body at the same time.
1. A head that can be coupled to a mixing apparatus, comprising:
a body defining a longitudinal axis and including a first side, a second side, a third side, and a fourth side, each of the sides including a projection, the body including a central member for supporting a microplate between the sides;
a first vertical channel defined by the body and configured to removably secure a first test tube so that its longitudinal axis is oriented perpendicular to the longitudinal axis of the body;
a second vertical channel defined by the body and configured to removably secure a second test tube so that its longitudinal axis is oriented perpendicular to the longitudinal axis of the body;
a first horizontal channel defined in part by the first side of the body and configured to removably secure a third test tube so that its longitudinal axis is oriented parallel to the longitudinal axis of the body;
a second horizontal channel defined in part by the third side of the body and configured to removably secure a fourth test tube so that its longitudinal axis is oriented perpendicular to the longitudinal axis of the body; and
wherein each of the channels defines a channel diameter and at least one of the first vertical channel, the second vertical channel, the first horizontal channel, and the second horizontal channel defines a channel diameter that is different than the channel diameter of the remaining channels.
2. The head of claim 1 , wherein the central member includes an elastomeric material.
3. The head of claim 2 , wherein the elastomeric material is positioned relative to an actuator for the motor so that when the head is coupled to the housing and a force is exerted on the elastomeric member, the motor is actuated.
4. The head of the claim 1 , wherein the at least one of the first horizontal channel and the second horizontal channel defines another vertical channel that is configured to removably secure a test tube to the body so that a longitudinal axis of the test tube orients in a direction perpendicular to the longitudinal axis of the body.
5. The head of claim 1 , wherein the first and the second vertical channels each include an aperture in the body, converging projections, and a wall.
6. The head of claim 1 , wherein the horizontal channels each secure a test tube with a snap-fit engagement.
7. The head of claim 1 , wherein the sides are substantially arcuately shaped in cross section and at least partially define at least one of the first horizontal channel or the second horizontal channel.
8. The head of claim 1 , wherein the projection of at least one of the sides is configured to engage a microplate with a snap-fit engagement.
