These polystyrene tweezers are ideal in situations where cross-contamination is a concern. After use, they can simply be discarded. Polystryrene tweezers should also be used in place of nickel-plated or stainless steel tweezers when processing with Physical Developer. The polystyrene won't react to the chemicals, unlike metals. Note that some solvents, such as those used in some DFO or Ninhydrin formulations, may damage polystyrene tweezers. Available loose or in individual hermetically-sealed packages. Each box includes 10 individual tweezers.
