INTRODUCTION

TECAN ASSAY PREPARATION SYSTEM MEGA

The TECAN MEGA is a fast, fully automated sample processor controlled by an external Personal Computer (PC). The instrument features two double diluters with independent syringes and four sampling tips an a single robotic arm.

Each tip is capable of performing aspirating, dispensing, or diluting operations at any position an the instrument's work table (see Figures 1-1a and 1-1b).

The robotic arm can move to any point of the work surface in X-direction (left-right). The four pipetting tips are mounted an a Y-slide, inside the arm, which allows free movement to any point in Y-direction (front-back). Finally, the four tips, independently of each-other, can be positioned to any height (Z-direction) within the workspace.

Two double diluters are used for the precise aspiration and dispensing of liquids in accurate volumes of 5 µl to 10ml.

The MEGA comes with the application software packalte MAP (MEGA Application Program) and a Tack set as ordered.

The MEGA's functionality may be extended by the optional Linear Rack Drive (MEGA ID) and the Fast Wash Module. The Linear Rack Drive allows sample identification by reading barcodes an the sample tubes. The Fast Wash Module minimizes the time required for the tip washing procedure.

Principles of Operation

The MEGA combines a system of microprocessor-controlled liquid handling components to one instrument. The system is con­trolled by software which resides an the hard dick of a personal computer (IBM PC model XT, AT or System/2). An operator implements the required liquid handling application method by the MAP software package.

Pipetting methods can be customized for test sample configuration, liquid handling parameters, and data management. Additional programs provided by TECAN permit routine diagnostic tests and assist the operator in troubleshooting component function.

The MEGA's hardware is based an a modular design concept in which each of the major functions is performed by a modular component. The principal liquid handling components of the Instrument are:

(1) Diluter/Dispenser

(2) X/Y/Z Movement Mechanism (Arm)

(3) Liquid Detector

(4) Wash Station

(5) Fast Wash Module (additional Option)

See figure 2-1 for a schematic diagram of the liquid handling system. The modular design of the MEGA maximizes the flexi­bility of the instrument and simplifies maintenance and service procedures.
