TL;DR: In this paper, a drug solution filling plastic ampoule having gas, steam and light ray barrier properties, a drug permeation preventing capability and an absorption/adsorption preventing capability, and a production method was described.
Abstract: A drug solution filling plastic ampoule having gas, steam and light ray barrier properties, a drug permeation preventing capability and an absorption/adsorption preventing capability, and a production method for the plastic ampoule. The drug solution filling plastic ampoule includes a container body, a fusion-bonded portion which seals a mouth of the container body, and a wrench-off holder tab connected to the fusion-bonded portion. The ampoule is formed from a parison including two or more layers, at least one of which is a functional layer having at least one characteristic property selected from the group consisting of a gas permeation preventing capability, a steam permeation preventing capability, a light ray permeation preventing capability, a drug permeation preventing capability and a drug absorption/adsorption preventing capability.

TL;DR: In this article, the authors show that the solid-liquid interface shape is convex when it lies within the heater and concave when it lie within the cooler, and that the dependence of interface position on travel rate, geometry of the ampoule, and on the relative temperatures of the warmer and cooler increases as the effectiveness of heat transfer between ampoules and the surroundings diminishes and as the thermal conductivity of the material increases.

TL;DR: In this article, a stepping-motor-driven syringe presses a mixture of helium and sample CO2 into the gas ion source, allowing continuous and stable measurements of different kinds of samples.
Abstract: In 2010 more than 600 radiocarbon samples were measured with the gas ion source at the MIni CArbon DAting System (MICADAS) at ETH Zurich and the number of measurements is rising quickly. While most samples contain less than 50 μg C at present, the gas ion source is attractive as well for larger samples because the time-consuming graphitization is omitted. Additionally, modern samples are now measured down to 5 per-mill counting statistics in less than 30 min with the recently improved gas ion source. In the versatile gas handling system, a stepping-motor-driven syringe presses a mixture of helium and sample CO2 into the gas ion source, allowing continuous and stable measurements of different kinds of samples. CO2 can be provided in four different ways to the versatile gas interface. As a primary method, CO2 is delivered in glass or quartz ampoules. In this case, the CO2 is released in an automated ampoule cracker with 8 positions for individual samples. Secondly, OX-1 and blank gas in helium can be provided to the syringe by directly connecting gas bottles to the gas interface at the stage of the cracker. Thirdly, solid samples can be combusted in an elemental analyzer or in a thermo-optical OC/EC aerosol analyzer where the produced CO2 is transferred to the syringe via a zeolite trap for gas concentration. As a fourth method, CO2 is released from carbonates with phosphoric acid in septum-sealed vials and loaded onto the same trap used for the elemental analyzer. All four methods allow complete automation of the measurement, even though minor user input is presently still required. Details on the setup, versatility and applications of the gas handling system are given.
