The Bühler 2000 portable sampler has compact dimensions with the 24 x 1L glass or plastic bottles or up to 25L composite bottles. All programming features of stationary sampler products are available. Cleaning efforts to avoid cross-contamination during indirect discharge monitoring are at a minimum owing to the innovative distributor design as well as usage of round shaped bottles. Available with autarkic active cooled sample base. Future safety: one sampler head combined with a passive or active cooling base can be used without adaptations.
