Necessity is the Mother of Innovation

Purpose: Generally speaking, scientific equipment manufacturing companies that correctly perceive and then meet research customer needs will succeed. Researcher-manufacturer cooperation is vital to such success. The two entities must have a real conversation about what the researcher uses as a process and how current containment is either ineffective or not present. The designer-manufacturer then makes recommendations and …
