Reference Standards and Markers



Reference StandardsEach “E”-vial reference source comes with a certificate of radio- activity calibration that guarantees accuracy within 5%. The critical nature of NRC and agreement state regulations for dose calibrator QC demand the most accurate reference sources available.

Reference sources can be purchased individually, or in cost-effective sets of three or four. Sets come in various combinations of radionuclide sources to fit your needs. An 18 month day to day decay calender is available to eliminate calculations.

If you need a reference source with an activity not listed in this catalog, Capintec can meet your special request promptly. Capintec will arrange for disposal of original source with purchase of replacement source.

Markers & Rulers

Spot Markers

Our Spot Markers are 1″ in diameter by 0.25″ and made of clear acrylic. The activity is supplied as a nominal value of ±15%. NIST traceable calibrations with accuracies of ±5% are available. A wooden storage box is also available (upon request).

If the activities above do not meet your specific requirements, give Capintec a call; other activities are available upon request.

“L” and “R” Spot Markers

In order to better mark the orientation of the patient, these spot markers containing 100 µCi of Co-57 identify the Left side and/or the Right side of the patient. The “L” and “R” are clearly identified on the patients film.

0975-S200 Spot Marker- Co-57, 200 µCi
0975-8030 Spot Marker- Au-195, 30 µCi

Rigid Ruler

The Capintec Rigid Ruler is a plastic tube 0.197″ (5.0 mm) in diameter, containing 15 sequential 0.394″ (10.0 mm) sections of Co-57 and inactive lead. The overall length of the ruler is 6.7″ (17 cm) with an active length of 5.91″ (15.0 cm). Contained activity is supplied as a nominal value ±15%. The standard Capintec Rigid Ruler contains 140 µCi (0.74 MBq) of Co-57. Other activities are available upon request.

Penpoint Markers

The Penpoint Marker is used in tracing the outlines of anatomical features on a patient. The trace appears almost instantly on the gamma camera display. Capintec’s Penpoint Markers contain 100 µCi of Co-57 in a bead at the end of an anodized aluminum rod. The pen-shaped rod screws into a brass cap which shields the active point.

Flexible Marker

Flexible Markers are useful in outlining anatomical parts or borders of organs on patients. Co-57 is uniformly dispersed in an epoxy matrix and contained in a 2.4 mm flexible plastic tube. The overall and active length of the marker is 19.7″ (50 cm).

Flexible Rulers

The Capintec Flexible Ruler is a plastic tube 0.19″ (4.8 mm) in diameter, containing 45 sequential 0.394″ (10.0 mm) sections of Co-57 and inactive lead. The overall length of the ruler is 18.5″ (47 cm), with an active length of 17.7″ (45 cm). Contained activity is supplied as a nominal value ±15%. The standard Capintec Flexible Ruler contains 20 µCi (0.74 MBq) of Co-57. Other activities are available upon request.
