Intensifying screens are ideal for optimum exposure speed and resolution. The high absorption with low noise sharpens image contrast and improves detection of beta-emitter (32P) and gamma-ray emitter (125I). choose enhanced screens for 30 to 40 percent more sensitivity than regular calcium tungstate screens. The screen's effectiveness is increased when exposures are conducted below -70°c. Get the results you need at an affordable price-compare to name brand blue-sensitive, double-emulsion film for performance and value. Ideal for western blotting, DNA sequencing gels, chemiluminescent probes, gel shift analysis, and commonly used radioisotopes (32P, 125I) double emulsion film gives you sharp contrast and exemplary resolution for DNA sequencing film is single-sided for exceptional clarity and low background.
