How to Recognize and Avoid Them Working in a laboratory involves risks and dangers through a variety of hazardous substances or situations. The types of danger can be divided into four classes: chemical hazards, electrical hazards, biological hazards and physical hazards. To be prepared for the dangers and be able to prevent them, you must first…

Optical spectroscopy in the ultraviolet and visible (UV/VIS) light spectrum is one of the most common techniques for the physical characterization of fluids in a laboratory environment. Based on the absorption of light by a sample, it is widely used across a broad range of fields and applications in research, production and quality control. UV/VIS…

TDI is produced through three main reactions: nitration, hydrogenation and phosgenation. The effluent from the third reactor is refined via distillation but not before remaining phosgene and hydrogen chloride are removed in a scrubber. As the reaction of phosgene with water is very slow, typically a caustic soda solution is chosen as a scrubbing agent…

Chemicals hazard symbols are not only found in the lab, they can also be found on some home products. Therefore it is necessary to know the meaning of each symbol. Some chemical hazard symbols are self-explanatory, some are not. The following overview covers common European hazard symbols and explains the dangers that they warn of.

The “Essential Measurement Techniques” Guide supports lab operators to recognize and avoid potential error sources and ultimately increase laboratory efficiency. Experience shows that modern, well-developed balances and analytical instruments do the most to promote ease of use, operational safety and accurate results. However, even with state-of-the-art solutions, practical know-how is still required for users to…

Optimizing efficiency and productivity is essential in the modern laboratory environment, and eliminating sources of waste is crucial to creating a lean laboratory. By identifying time-consuming or unnecessary activities that do not add value, laboratories can reduce or eliminate these tasks to enhance and simplify their workflows. Lean principles identify 8 types of laboratory waste…
