A Simple Method for Filling Ampoules
نویسندگان
چکیده
Wright (1912) described a method for filling ampoules based on the principle of first exhausting the air from the ampoules and then filling by atmospheric pressure. Since then many elaborate pieces of apparatus have been devised based on the same principle, but these are^ all expensive and not readily obtainable. The ^odification described below has the advantage that the apparatus required may be found in every laboratory, and the ampoule containers afe suc^ a nature that they can readily be ?btained in the market and cost only a few

A simple, precise, rapid and low-cost potentiometric method for pethidine determination in pharmaceuticals and urine is proposed. A chemically modified carbon paste electrode (CMCPE) for pethidine hydrochloride (PDCl) based on pethidine-phosphotungstate (PD-PT) as ion-pair complex was prepared and fully characterized in terms of composition, usable pH range, response time and temperature. The p...

The international Reference Reagent for anti-HPV 16 (05/134) was established by ECBS in 2007. This material was not given the status of International Standard as the residual moisture was more variable than usually observed in serum fills. Two additional studies have been undertaken in which ampoules were assayed for residual moisture using non-invasive techniques so that antibody assays could ...
متن کاملFilling up another Gap: Synthesis and Crystal Structure of Ba2H3I
Colorless and transparent single crystals of Ba2H3I were obtained by reacting Ba with dried and sublimed NH4I in a 4 : 1 molar ratio in silica-jacketed Nb ampoules at 1100 K for 13 h. The crystal structure of the title compound was determined and refined by means of single-crystal X-ray diffraction. Ba2H3I crystallizes in a stuffed anti-CdI2 structure isotypic to Sr2H3I in the space group P3̄m1 ...
