Instrument Shop

The Center for Radiological Research, directed by Gary Johnson, offers the most comprehensive design and instrument shop in the Columbia-Presbyterian Medical Center complex. Established in 1947, the facility has been continuously modernized and updated. Using a CAD (computer aided design) system, specialized, complex, custom-made instrumentation and equipment of almost any physical size, including micro-machining of plastics, metals, and ceramics, can be fabricated. Consultation with, and guidance for researchers is provided in determining appropriate materials and design, along with technological advice and suggestions. The shop is also equipped for micro-brazing and micro-silver soldering, as well as for plastic molding and mechanical repair of small laboratory equipment.

The facility is a world leader in the fabrication of ionization chambers and proportional counters used in radiation studies and in microdosimetry. Other specialized items produced include imaging systems such as intravital microscopes and customized PET scanners.

Charges are based on intricacy of work requested, plus materials.

Items routinely made include:

Radiation targets and radiation shields including beta-particle bench shielding, bins, storage and work boxes and lead containers and shields Collimators (lead or tungsten) 
Custom-made microscopes and modifications such as temperature chambers and specialized stages
Cell flow and micro-sieving chambers 
Gimbal systems 
Positioning systems 
Micro slides (x-y-z) 
Surgical stainless steel implants (neurological and orthopedic) 
Micropipette holders 
Electrophoresis units and custom combs 
X-ray targets and phantoms
Vacuum systems
