1. The Residual and Temperature-Dependent Resistance of Reference-Grade Platinum Wire Below 13.8 K
Published: 9/12/2013
Authors: Weston Leo Tew, William E. Murdock, Michal J Chojnacky, Dean C Ripple
Abstract: We report the Residual Resistance Ratio (RRR) and resistance ratio W(GaMP) (gallium melting point) values for well-annealed samples of the original SRM 1967, its contemporary substitute SRM 1967a, and a collection of NIST capsule-type SPRTs. The RRR ...

2. Data Logger Thermometers for Vaccine Temperature Monitoring
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7899
Published: 11/23/2012
Author: Michal J Chojnacky
Abstract: Complete and accurate records of vaccine temperature history are vital to preserving drug potency and patient safety, yet many vaccine providers do not use continuous temperature monitoring systems in their vaccine refrigerators. We evaluated the ...

3. Thermal Analysis of a Small Pharmaceutical Refrigerator for Vaccine Storage
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7900
Published: 11/23/2012
Author: Michal J Chojnacky
Abstract: Each year, billions of dollars of vaccines are stored in refrigerators at the facilities of a variety of medical providers. Many vaccines must be maintained in the range 2 °C to 8 °C to retain product potency. As an extension to our study of hous ...

4. The Residual Resistance Ratio of High-Purity Platinum
Published: 8/22/2011
Authors: Weston Leo Tew, William E. Murdock, Michal J Chojnacky, Dean C Ripple
Abstract: High-purity platinum wire is produced for use in both Standard Platinum Resistance Thermometers (SPRTs) and type S and type R thermocouples. The resistance ratio W(T90) and thermoelectric characteristics of the wire are a function of chemical purity ...

5. Thermal Analysis of Refrigeration Systems Used for Vaccine Storage
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7656
Published: 11/2/2009
Authors: Michal J Chojnacky, W Wyatt Miller, Dean C Ripple, Gregory F Strouse
Abstract: Each year, billions of dollars of vaccines are stored in refrigerators at the facilities of a variety of medical providers. Many vaccines must be maintained in the range 2 °C to 8 °C to retain product potency. We have tested the performance of two t ...
