A selection of the most common extraction techniques are listed in Table 1. Each of the techniques will then be discussed, detailing what is involved to set up the equipment, the advantages and disadvantages as well as some of the limitations of each technique. The primary aim of any extractable study is the acceptance or rejection of a given material. The acceptance or rejection can only be achieved with knowledge. This can be achieved by a number of ways, including; understanding of the materials likely composition, manufacturers information and the definitive testing. In all aspects of extractable testing it is important to remember that the extraction is not so vigorous as to deform or degrade the material which would likely produce extractables that will not be observed as leachables. Extractables are potential leachables, it is the leachables that the patient is exposed to and are of toxicological concern.

  • Improved Automatic Steam Distillation Combined with Oscillation-Type
    Lachenmeier et al. SpringerPlus (2015) 4:783 DOI 10.1186/s40064-015-1574-6 METHODOLOGY Open Access Improved automatic steam distillation combined with oscillation‑type densimetry for determining alcoholic strength in spirits and liqueurs Dirk W. Lachenmeier1* , Leander Plato1, Manuela Suessmann1, Matthew Di Carmine2, Bjoern Krueger3, Armin Kukuck3 and Markus Kranz3 Abstract The determination of the alcoholic strength in spirits and liqueurs is required to control the labelling of alcoholic bev- erages. The reference methodology prescribes a distillation step followed by densimetric measurement. The classic distillation using a Vigreux rectifying column and a West condenser is time consuming and error-prone, especially for liqueurs that may have problems with entrainment and charring. For this reason, this methodology suggests the use of an automated steam distillation device as alternative. The novel instrument comprises an increased steam power, a redesigned geometry of the condenser and a larger cooling coil with controllable flow, compared to previously available devices. Method optimization applying D-optimal and central composite designs showed significant influ- ence of sample volume, distillation time and coolant flow, while other investigated parameters such as steam power, receiver volume, or the use of pipettes or flasks for sample measurement did not significantly influence the results. The method validation was conducted using the following settings: steam power 70 %, sample volume 25 mL trans- ferred using pipettes, receiver volume 50 mL, coolant flow 7 L/min, and distillation time as long as possible just below the calibration mark. For four different liqueurs covering the typical range of these products between 15 and 35 % vol, the method showed an adequate precision, with relative standard deviations below 0.4 % (intraday) and below 0.6 % (interday).

  • Drilling Engineering Laboratory Manual
    KING FAHD UNIVERSITY OF PETROLEUM & MINERALS Department of Petroleum Engineering PETE 203: DRILLING ENGINEERING LABORATORY MANUAL APRIL 2003 PREFACE The purpose of this manual is two fold: first to acquaint the Drilling Engineering students with the basic techniques of formulating, testing and analyzing the properties of drilling fluid and oil well cement, and second, to familiarize him with practical drilling and well control operations by means of a simulator. To achieve this objective, the manual is divided into two parts. The first part consists of seven experiments for measuring the physical properties of drilling fluid such as mud weight (density), rheology (viscosity, gel strength, yield point) sand content, wall building and filtration characteristics. There are also experiment for studying the effects of, and treatment techniques for, common contaminants on drilling fluid characteristics. Additionally, there are experiments for studying physical properties of Portland cement such as free water separation, normal and minimum water content and thickening time. In the second part, there are five laboratory sessions that involve simulated drilling and well control exercises. They involve the use of the DS-100 Derrick Floor Simulator, a full replica of an actual drilling rig with fully operations controls, which allow the student to become completely absorbed in the exercises as he would in an actual drilling operation. The simulator has realistic drilling rig responses that are synchronized to specific events, like rate of penetration, rotary table motion, and actual rig sounds such as accumulator recharge, break drawworks, etc. It is hoped that the material in this manual will effectively supplement the theory aspect presented in the main course.

  • A Modified Device for Rapid Selection of Soil and Water Nematodes from Mixed Suspension
    Nematol. medit. (1976), 4: 245-247. I Section of Plant Pathology and Nematology, Department of Botany, Aligarh Muslim University, Aligarh-202001, India A MODIFIED DEVICE FOR RAPID SELECTION OF SOIL AND WATER NEMATODES FROM MIXED SUSPENSION by M.M. ALAM An earlier device (Alam, 1975) for selectively picking up large number of soil or fresh water nematodes was modified and appears to be an improvement over similar devices (Minteer, 1965; Shukla et aI., 1971; Khan et al., 1972) because of its speed and semplicity. The entire apparatus can be easily assembled in any laboratory and does not require any specialised components. Assembley and opera­ tion details are as follows: Construction details: Two L-shaped glass tubes (0.5 cm dia­ meter) of 4 and 5 cm lengths were inserted into the neck of a sepa­ rating funnel 'D' (l00 ml capacity) with the help of an air tight rubber stopper. One of the L-shaped tubes (5 cm length) was con­ nected through a rubber tubing (75 cm length, 0.5 cm diameter) to anoter glass tube' E' (15 cm length, 0.7 cm diameter) which was provided with a fine tip (7 cm length). The other L-shaped tube (4 cm length) was connected through a rubber tubing (0.5 cm diameter) of desirable length, to an aspirator' B ' (syn. filter pump) which was attached to a water tap' A'. The separating funnel was supported by a retort stand ' C' (Fig. 1). Operation: Before use, the stopper of the separating funnel , D' was closed and then the water tap 'A' was opened to start suction of air into the aspirator' B' resulting in a partial vacuum in the separating funnel' D '.
