The ISOMED 2010 is a PC-based dose calibrator of the newest generation. It is available with several types of PC-systems (nettop, laptop, mini-PC, terminal) with LCD-monitor or LCD-touchscreen, combined with the well-established MED ionization chamber. The integrated library with nuclides, compounds, containers and contents can be edited and expanded by the user or system operator, which allows very precise measurements and detailed data storing.

Benefits

• Calibrated for more than 30 nuclides, also for β-emitting nuclides
• Calibration factors for different containers
• Activity calculation for freely definable application times
• Measurement and compensation of background
• Measuring chambers with several dimensions available
• Network connection with patient information system possible

The integrated menu for quality control consequentially fulfils all requirements of DIN 6855-11 and the requirements of medical authorities (e.g. national institute for standards and metrology). The user’s menu of the dose calibrator supports in performing the (partially daily) quality controls (background, responsiveness) and documents the results as an evidence. For background quality control, a measurement with and without sample holder are made after each other. The activated schedule check reminds of the linearity check which has to be made every 6 months. It is practical and useful to carry out the linearity check automatically during weekend. In that case, a measurement of the Tc-elution is made every 3 hours. The linearity progress can also be printed as a curve. Additionally, a menu for checking Molybdenum breakthrough according to DIN 6854 is available.

This state-of-the-art touch-screen dose calibrator combines the best of both worlds: it has the extended functionality of a softwarebased
computer and the stability of a stand-alone unit. Like all Comecer dose calibrators, each model is used in combination with a
completely digital VIK-202 or VIK-203 ionization chamber.

The device has an ergonomic and intuitive touch-based design and is optimised to support the work flow of the user.
Performing the daily quality control will only take a tap or two on the brilliant and crisp 10” screen.
Built-in functionality includes:

• Mo-99 breakthrough set
• Identity test
• Daily/weekly/yearly tests
• Containers/geometries
• Syringe preparation.

VDC-606 has CE marking for medical devices and is FDA approved.

The heart of every Comecer dose calibrator is the ionization chamber: a completely digital detector that gives a fast and reliable
reading.

The 100% digital output allows the detector to be flexibly integrated into other instruments or structures with no need
for a converter or a separate reading unit.

The VIK-202 ionization chamber is pressurized at 14 bar (absolute) of Argon and its measurement field is up to 2 Ci of F-18; the VIK-
203 ionization chamber is also available, pressurized at 1.4 bar (absolute) of Argon, for a measurement field of up to 20 Ci of F-18.
