The Thermostatic Shaking Water Bath (BK-WBS30C / BK-WBS30R) supports BOD measurement in water analysis, cultivation and preservation of bacteria, viruses, molds, and microorganisms, plant cultivation, and breeding experiments. Two models provide rotatory (BK-WBS30C) or reciprocating (BK-WBS30R) shaking motion to match specific application requirements. Both models include a universal spring clamp tray and share identical heating and control specifications.
