Thecla Dispensing Isolator


  • Material introduction chamber (airlock) with air quality complying with Class B “At rest” (EEC-cGMP)
  • Dispensing chamber with air quality complying with Class A “At rest” (EEC-cGMP) and equipped with laminar flow over the entire area
  • Semi-automatic integrated dispensing system for syringes
  • 68Ge/68Ga generator housing compartment
  • Dose calibrator compartment equipped with pneumatic system
  • Final product extraction system in shielded container by means of specific compartment

THECLA Class A shielded isolator with integrated dispensing system mainly consists of:

  • a Class A main chamber, featuring a shielded front door with hand access and equipped with a Comecer dose calibrator mod. IBC Dose Calibrator (measurement range up to 2 Ci)
  • a Class B pre-chamber for materials introducing, located under the work surface of the main chamber
  • a built-in semi-automatic dispensing system for syringes
  • a syringe unloading system to extract the final product inside shielded containers.

The THECLA isolator has a compact and essential design, as well as being supplied with standard equipment: this makes the THECLA isolator extremely easy to use, meaning that it is one of the most competitive shielded isolator on the market.

Thanks to its small size, it can be positioned in confined spaces, also against the rear wall and with little space on the side: indeed, maintenance is carried out from the front wall.
