Dose Calibrator Model VDC 505

Produced by Veenstra Instruments

Dose Calibrator Model VDC 505 (.pdf)

This state of the art dose-calibrator combines the best of two worlds. It has the extensive functionality of a software driven device like the Veenstra VDC-405. It has the robustness of firmware like the Veenstra VDC-404. So if you do not want to introduce another PC in your department or Hotlab, the VDC-505 is the bestalternative.

All VDC dose calibrators come as standard with one well liner and dipper. Optional extras available are:

- Extra lead shielding

- Mo-99 breakthrough set

- Copper dipper

- Extra well liner

- Extra dipper

- Label printer

In terms of connectivity the VDC-505 is state of the art. The dose calibrator can be integrated in a network (Ethernet base) and connected to a PC or extra display. Furthermore the system supports a range of label-printers In terms of functionality the VDC-505 is well equipped for both vial and syringe measurements, including future dose calculations. Furthermore this model offers a complete set of calibrator quality control routines and protocols for daily and quarterly checks. These QC reports can then be downloaded to a PC by a standard RS-232 or even the optional Ethernet interface.
