VWR Life Science UnDo™ X-Ray Film Background Reducer

Supplier: VWR
UnDo X-Ray Film Background Reducer kit easily and proportionally reduces the signal on overexposed film

The kit includes two solutions that are used sequentially to oxidise and remove silver deposits on the exposed x-ray films. First, the silver grains are oxidised on the film by Solution A and then Solution B is used to stop the oxidation reaction and dissolve the oxidised silver grains. A short wash in distilled water completes the reduction process, which may then be repeated as needed to achieve the desired results. The original data is preserved due to proportional removal of silver from low and high density areas on the film. The result is an optimised image that reduces ambiguous data interpretation and the need for repeating experiments in many instances.

Ordering information: Kit includes UnDo™ X-Ray Film Background Reducer Solution A, 1 L and UnDo™ X-Ray Film Background Reducer Solution B, 1 L.
