An Efficient Vacuum Apparatus for Microtechnic
AN EFFICIENT VACUUM APPARATUS FOR MICROTECHNIC EUGENE B. WITTLAKE1 The Ohio State University From time to time notes on vacuum apparatus and its applications to micro- technic have been published. These papers, with the exception of very few instances, do not deal with the actual measurement and control of vacuum, the effect of vacuum on tissues and the pumping of tissues in reagents not miscible with water and water vapor. It seemed necessary, therefore, to check the above conditions and to determine, if possible, their relation to fixation, dehydration and infiltration of paraffin in plant material in the "in vacuo" process. Lebowich (4) in 1936 developed a soap-wax medium for the simultaneous dehydration and infiltration of human tissues. In this technic he employed a vacuum apparatus consisting of a faucet aspirator and a wide-mouthed bottle placed in an oven automatically controlled for temperature. Later Moritz (5) modified Lebowich's vacuum pump. Instead of using the expensive equipment which Lebowich had at his disposal, Moritz attained the same end with ordinary laboratory equipment obtainable by any technician. In the same paper he presented a modification of Lebowich's dehydration schedule. In the technics of both of these men a vacuum apparatus was used to definite advantage in regard to time and thoroughness of preparation of tissues. In April 1940 Chermock and Hance (2) announced the use of a vacuum pump for general micrology. Their principle dehydration agent was "methyl cellosolve" which they used in a vacuum apparatus of simple and convenient construction. Their accessory devices were a thermometer and a water trap. -

Construction and application of a novel combination glove box deposition system to the study of air-sensitive materials by tunneling spectroscopy K. W. Hipps and Ursula Mazur Department of Chemistry and Chemical Physics Program, Washington State University, Pullman, Washington 99164-4630 (Received 27 February 1984; accepted for publication 20 March 1984) The construction and application of a high-vacuum deposition system housed in a recirculating, catalytically scrubbed, inert-atmosphere glove box is reported. This system is specifically applied to the fabrication of tunnel diodes used in a surface vibrational spectroscopy called inelastic electron tunneling spectroscopy or lETS. Through the use of this inert-atmosphere adsorption/ fabrication system, tunneling spectra have been obtained from a variety of air-sensitive compounds adsorbed on aluminum oxide. Up to now, spectra of some of the species reported here have been unattainable by the adsorption techniques used in lETS. -

XXXIK-The Collection and Examination of the Gases Produced by Bacteria from Certain Media
View Article Online / Journal Homepage / Table of Contents for this issue 322 PAKES AND JOLLYMAN : COLLECTION AND EXAMINATION XXXIK-The Collection and Examination of the Gases produced by Bacteria from certain Media. By WALTERCHARLES CROSS PAKES and WALTERHENRY JOLLY AN. DURINGthe course of an investigation upon the bacterial flora of the water of a certain well, several specimens of bacteria were isolated which belonged to the group of Bacillus jhorescens Ziquefcccielzs. The determination of the cultural reactions enabled us to divide these into two groups, (1) that which produced gas, and (2) that which produced no gas in media containing nitrate. These were provisionally designated 5.0.7 and S.0.6 respectively. In order to obtain more information concerning the former of these, it was decided to analyse the gas produced . As the various forms of apparatus hitherto described for the purpose of the collection of gas thus produced did not seem to be sufficiently accurate or suitable for our purpose, we designed one which is both simple and accurate. It was necessary to have an apparatus which fulfilled the following conditions : (1) A relatively large amount of medium must be used-from 300 to 500 C.C. (2) The gas receiver must have a capacity of at least 600 C.C. (3) It must be easy to inoculate the medium without any chance of accidental contamination. (4) The receiver must be fitted with taps so that a part or the whole of the gas can be removed during the course of the experiment with- out chance of contamination. -

The Fluorescent Properties of a Stalactite Sample Using the Cary
The fluorescent properties of a stalactite sample using the Agilent Cary Eclipse fiber-optic probe accessory Application Note Author Daren Fyfe PhD Introduction Agilent Technologies The fluorescent properties of secondary carbonate cave deposits Mulgrave, Victoria 3170, (speleothems) are related to the environmental conditions under which they Australia form (for example, soil type, climate and vegetation, and formation of metal ion complexes).1 Speleothem fluorescence is derived from organic acids (humic and fulvic) that precipitate with speleothem calcite after passing though surface layers in rainwater. Using non-destructive fiber-optic technology, the fluorescent properties of these speleothems can be investigated in order to further understand palaeoenvironmental trends. The Agilent Cary Eclipse fiber-optic probe accessory takes light to the sample via an optical light guide. This allows the investigation of the fluorescent properties of samples that cannot be analyzed using more traditional means such as a cuvette or microplate reader2, which are subject to size restrictions or complicated handling requirements. The present study aimed to examine the fluorescent properties of the surface of a cross-sectioned speleothem (stalactite) sample using a Cary Eclipse equipped with fiber-optic coupler and probe. Materials and methods Using the solid sample tip, the probe tip was positioned (For part numbers please see Reference 5) at 45° to the surface of the cross-sectioned stalactite sample using a retort stand and clamp. The solid Equipment sample tip was flush with the surface of the stalactite. Agilent Cary Eclipse fluorescence Using the ‘Scan’ software in ‘3D Mode’, contour plots spectrophotometer of excitation versus emission were collected under Fiber optic coupler ambient laboratory lighting conditions, as a function of distance along the stalactite.
