Description
Tween® 40 is a Ph.Eur.-grade material supplied for laboratory and life-science use, identified by CAS number 9005-66-7. Manufacturer data list a density of 1,08 g/cm³ and a flash point above 113 °C, giving clear physical reference points for handling, storage planning and method documentation. The product is As a recognised Tween® surfactant grade meeting Ph.Eur. requirements, it fits workflows that specify pharmacopoeial quality for non-ionic detergents. Density and flash-point values support risk assessment and process design, while the CAS number anchors identity in purchasing and inventory systems. balances bench-scale consumption with economical restocking for shared laboratory stocks. Tween® 40 from manufacturer Carl ROTH is positioned for life-science and biochemistry detergent use where Ph.Eur. alignment and transparent physical data matter. Laboratories can integrate the stated density, flash point and CAS information directly into SOPs and material registers, with the plastic pack supporting clean, practical day-to-day handling.
