Abstract
Disclosed is a fraction collector for dispensing liquids into plural receptacles (P1,P2) arranged in a two dimensional array. The fraction collector comprises a table (22) for supporting said receptacles, and an arm supported above the table, in tum supporting a liquid dispenser (35), the fraction collector arm is rotatable about an arm axis (C) and the liquid dispenser is movable along the arm on a carriage 34 (FIG. 2). Thereby, the dispenser is low cost and is repositionable simply above the receptacles as a result of said rotation and as a result of said movement along the arm, without occupying too much laboratory bench space.
Claims17
A fraction collector for dispensing liquids into plural receptacles arranged in a two dimensional array of rows, the fraction collector comprising:
- a controller;
- a table for supporting said receptacles, and
- an arm supported above the table, in turn supporting a liquid dispenser,
- wherein the arm is rotatable about an arm axis and the liquid dispenser is linearly movable along the arm, and
- wherein the controller is configured to control the arm to reposition the dispenser to any possible dispensing position above the receptacles as a result of said rotation and as a result of said linear movement along the arm.
A fraction collector comprising:
- a controller,
- a housing protecting drive elements, the top of the housing being formed as a table, the table having at least two receiving positions each for receiving a microplate each microplate including a plurality of liquid receptacles arranged in rows, and
- a rotatable arm supporting a liquid dispenser,
- wherein the arm is configured to reposition the dispenser substantially above any receptacle by a combination of rotational motion and linear motion of the dispenser along the arm, said arm having a rotational axis extending generally perpendicular to the table between the two microplate receiving positions.
