Supplier: GERHARDT

Description: For rapid determination in accordance with Weender, Van Soeste et al. Use fine mesh bags to weigh the sample. A glass diffuser is then placed inside the bag, allowing the reagents to diffuse freely. Six samples can be processed simultaneously: clean, boil in sulphuric acid, rinse, boil in KOH, rinse again and dry.

Catalog Number: (181-0310)

Supplier: VWR Collection

Description: The VP 220 is ideal for rotary evaporators providing the powerful vacuum needed for demanding evaporations without the use of oil pumps. VP 220 has built-in Advanced Vapour Management (AVM) which means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases. The VP 220 is especially effective for rotary evaporation of low boiling point solvents such as acetone and ethanol and is able to rapidly strip DMF at 35 °C. The pump parts are all made of corrosion resistant materials such as PTFE and Kalrez to handle aggressive vapours, and together with vacuum adjustment, the evaporation process will be optimised. Use the vacuum adjustment to increase the vacuum until bubbles form in the evaporation flask - then lower it slightly. Reduce the vacuum for fast reaction to bumping or foaming.

Description: Undecane may be used as an internal standard in gas chromatography when working with other hydrocarbons. Since the boiling point of undecane (196 °C) is well known, it may be used as a comparison for retention times in a gas chromatograph for molecules whose structure has been freshly elucidated.
