The Gammacell® 40 Exactor is designed to be a stand alone research irradiator.  With its accurate and reproducible performance, the Gammacell® 40 has been relied upon by researchers worldwide to advance their cancer and stem cell scientific studies.

Unrivalled Precision and Versatility

The Gammacell® 40 Exactor Low Dose Rate Research Irradiator is used in labs throughout the world to explore elements of cell biology, and advance the scientific study of various areas of cancer and stem cell research.

The Gammacell® 40, with its state-of-the-art control system, is engineered to give precise results.  Timer settings can be chosen in increments of one second up to 100 hours and the control system allows manual or automatic operation.  Dose uniformity is ensured through the use of two Caesium-137 sources and an electric drive mechanism which provides accurate results regardless of where specimens are placed in the large sample container.

A Research Tool by Design

Research environments demand execution of protocols to exacting standards and replication of work with unfailing accuracy.  The Gammacell® 40 is designed and engineered to meet these research environment requirements.

The Gammacell® 40 has a wide range of applications in radioimmunology, radiosensitivity and cell biology.  It is ideal for the irradiation of mitotically inactive cell culture media, mixed lymphocyte cultures and cellular blood components.

The Gammacell® 40 also has a large ventilated sample container which makes it an excellent research tool for the development of murine models for cancer therapy.

Efficient, convenient and user friendly, the Raycell® Mk2 X-ray Blood Irradiator provides a safe and cost-effective choice for blood irradiation – backed by Best® Theratronics’ trusted expertise and commitment to quality.  It delivers the required dose to help prevent TA-GVHD.

Raycell® Mk2 Features

  • Larger canister size facilitates irradiating more blood bags – 2.0 L and 3.5 L (0.53 and 0.92 US Gallons).
  • Two opposing x-ray tubes deliver a uniform dose to the product.
  • Dose delivery is controlled by setting and monitoring the irradiation time, based on the central dose rate.
  • Irradiation time is controlled by two independent microprocessors.
  • Detailed dosimetry of the sample canister volume is obtained and provided at the time of installation.
  • Installation can take 1-3 days depending on individual installation and training requirements.

Irradiated Products Database Management (IPDM)
System Features (Optional):

  • Scans and stores bar-coded information about the irradiated product (unit number, product code, blood type, etc.), irradiation cycle number, operator details, date/time stamp, and irradiation indicator verification.
  • Scans barcodes using ISBT 128 and ABC Codabar decoders, or as is without decoding.
  • Includes three modes of operation: product entry, cycle database review, and administration.
  • Performs additional verification of the irradiation time.
  • Stores up to 10,000 cycles or 50,000 product entries of data in main database, and archives the rest.
  • Exports data conveniently onto a USB memory stick (1 stick provided, 2 USB ports).
  • Ensures efficient, error-free operation.

Superior Performance and Unparalleled Dose Uniformity

X-rays are produced by bombarding targets with electrons, which are accelerated in a vacuum through a high-voltage electrical field.  The dose is delivered by two opposing X-ray tubes with the sample canister located centrally between them.  The two cone-shaped beams ensure that a tight dose is delivered to the product and exceptional dose uniformity is attained.

The Gammabeam™ X200 (GBX200) is among the most versatile research irradiators available today.  Suited to a broad spectrum of applications including secondary standards dosimetry, sterile insect programs, and medical or veterinary research, the unit provides your lab with a powerful tool.  The Best® Theratronics GBX200 is the latest in a long line of irradiators that researchers and clinicians have trusted and depended on for decades.  Its expert design is based on more than 45 years of irradiator experience and backed by an industry-leading commitment to safety, quality, and customer support.

The GBX200 has a Cobalt-60 capacity of 434 TBq (11,725 Ci) and can deliver a dose rate of 800 cGy/min at 50 centimeters from the source at maximum field size.  With easy-to-use controls and safety features that meet or exceed all applicable regulations, the unit is a valuable tool for those requiring a dry storage panoramic field irradiator.

To assist with installation, Best® Theratronics provides a standard shielded-room drawing on which site specific design plans can be based.

The GammaBeam™ 100-80 is a new design based on the reliable Theratron Phoenix that offers more functionality, safety and improved user interface.  Its basic design makes it simple to use and easy to maintain while maximizing reliability where service support is limited.  Moreover, the compact control console makes basic functions intuitive, thereby reducing the complexity of operator training while augmenting its patient treatment capacity.
