densitometer
/ˌdɛnsɪˈtɒmɪtə
/noun
1A device for measuring the density of a material.Relative protein levels were determined by scanning the immunoblot with a laser scanning densitometer....
- Unfortunately the stain cannot be read by densitometers that measure only white light.
- Measurement of signal intensity was performed with a laser densitometer (Bio-Rad) using the Molecular Analyst program on an IBM compatible computer.
2An instrument for measuring the photographic density of an image on a film or photographic print.If you do not have a densitometer, you will have to print the negative to determine if its density and contrast range are suitable....
- It is time to set aside the densitometer and resume my artistic endeavors.
- Photographs of the implants were taken with ‘control implants’ (an unused piece of nylon to correct for differences in film development) and analyzed with a densitometer.

densitometric
- For sixteen pools, each representing a high or low pool of a specific sire-by-marker combination, densitometric estimates of allele frequency were compared to estimates of allele frequency obtained by individual genotyping.
- Quantitative comparisons between each evolved clone and the ancestor are based on densitometric analyses of the gels.
- The authors conclude that fully automated cell counts and densitometric analyses of bronchial biopsy tissue from patients with asthma are unbiased and decrease the variability in measures of inflammation.
densitometrically
- When the intensity of the bands of double-stranded DNA was densitometrically analyzed, a dose - response relationship and a time-dependence were observed.
- The intensity of bands indicating digestion was densitometrically measured and an average for two independent amplifications and three independent digestions was calculated.
- The intensity of the band was measured densitometrically and found to make up maximally 10% of the total amount of the applied protein.
densitometry
- Bone densitometry is a simple, painless, computerised X-ray technique that allows measurement of bone density.
- Osteoporosis is best diagnosed by a procedure known as bone densitometry.
- The rate of synthesis of late-gene or middle-gene products at each time was measured by densitometry of each protein band and expressed in arbitrary units.
