An automated microdoser

DESCRIPTION

DT-03 ::: Description ::: Features ::: Delivery set ::: Software

用于精确注射液体，针头可抛弃（可选容积1, 2, 5 or 10 ml）。

An automated microdoser DT-03serves for precision supply or bleeding of liquids with the help of changeable standard syringe (disposable plastic syringe of volume 1, 2, 5 or 10 ml). The microdoser can be employed, for example, for drop formation at the limiting wetting angle experimental measurement, for feeding solutions with solvent or active ingredients, for replenishing the monomolecular film inLangmuir—Blodgett trough etc. The microdoser features reversable motion of the leading rod that allows to draw the liquid back into the syringe.

The device design provides simple routine for the syringe installation/change and a possibility to move the leading rod manually. The microdoser mechanism can be deflected to angle 75° back from its vertical position on the supporting stand.

For the microdoser positioning in horizontal plane relative base (substrate), it can be employed together with the XY positioning stage. Stepper motors of both the microdoser and XY positioning stage can be driven fromcontrol program run on host PC.

The microdoser DT-03 driving mechanism is unified with that of dipper VT-04 that allows their mutual conversion by simple change of the unit front panel.

软件

Control software for microdoser DT-03 is a unified program for driving three stepper motors. It is a 32-bit Windows application that runs under Windows XP SP2 and higher operating systems.

The software provides control over the stepper motor speed, motion range (in steps of the stepper motor or in mm) and motion direction.

The program can be employed for driving three stepper motors. If the device is additionally equipped with XY positioning stage, all the three axes motions can be automated.

As an alternative for the unified program, control program for Langmuir—Blodgett trough can be employed in which custom scripts can be used to control the mechanism motion.

Minimal configuration of host PC (not included in the delivery set): Celeron^®1.7 GHz, RAM 128 MB, HDD 40 GB, VRAM 64 MB, monitor 1024x768x32 bit, MS Windows^® XP SP2, free USB port.
