SELECTA 500 SX
Cherry picking, tube filling, weighing and labelling robot
A robotic cherry picking system with integrated weighing, decapping, liquid handling and tube labelling options. Especially suited to any precision liquid handling tasks that require automated application of tube specific labels together with data from integrated 4-figure balance.
SELECTA 500 SX is the next generation of cherry picking robot from HTZ designed for applications requiring selective processing of tubes and vials. Building on the capabilities of our previous models the SELECTA 500 SX now offers faster processing, larger deck size and a tube labelling option.
Typical processing tasks performed by the SELECTA 500 SX include:
SELECTA 500 SX Modules
Tube Labelling Module
An extremely robust and flexible tube labelling option may be supplied with the SELECTA 500 SX. Tubes, vials and bottles may be presented by the robotic gripper and label applied. The format, size of label and type of label material can be specified including labels that tolerate -80 degrees.
The data printed on the label can include barcode and other sample specific information together with gravimetric data when combined with the Weigh Station option.
SELECTA has up to 2 independent Zdrives. Each can accommodate a pipetting needle connected to a high-resolution syringe drive.
A Typical Process
One example application suitable for automation by the SELECTA 500 SX is where plain glass vials need to be filled with an accurate volume of liquid and where the weight of the liquid needs to be incorporated into the label that is applied. This includes the following main steps:
1. An empty vial is selected by the robotic gripper from a rack located on the deck
2. The vial is moved onto the Weigh Station Module and a tare weight is obtained and recorded
5. The vial is then presented to the Tube Labelling Module where a label is applied to the vial. The label can include any data related to that individual vial including the weight of the liquid just dispensed
6. The vial is then returned to its original rack - or placed in a separate receiving rack
Incorporating updated electronics and a rotating tube gripper it provides a number of new capabilities over other models:
Tubes may be presented in a variety of different rack types but typically they are in 96 position SBS format blocks. Custom racks are avalable for high-density loading of vials. Racks suitable for direct transfer to freeze driers also available.
Identification of tube codes, either 2D or linear barcode, is achieved by means of the integral camera, 2D scanner or laser barcode reader.
SELECTA 500 SX is controlled by our advanced robotic instrument control suite giving the user the ability to readily configure the instrument for a number of different tasks, deck layouts and tube types. The software provides a graphical display of the instrument during processing so that progress can be readily monitored.
The deck can be configured to accommodate up to 15 SBS format racks plus reagent racks in addition to the Weigh Station and 2D barcode reader.
Probe Wash Station
When transfering liquiids the pipetting needle is washed in between samples in a Probe Wash station that washes both the inside and the outside surfaces of the probe needle.
