Laboratory Glassware n Edition No. 2 n Index Introduction 3 Ground joint glassware 13 Volumetric glassware 53 General laboratory glassware 65 Alphabetical index 76 Índice alfabético 77 Index Reference index 78 [email protected] Scharlau has been in the scientific glassware business for over 15 years Until now Scharlab S.L. had limited its sales to the Spanish market. However, now, coinciding with the inauguration of the new workshop next to our warehouse in Sentmenat, we are ready to export our scientific glassware to other countries. Standard and made to order Products for which there is regular demand are produced in larger Scharlau glassware quantities and then stocked for almost immediate supply. Other products are either manufactured directly from glass tubing or are constructed from a number of semi-finished products. Quality Even today, scientific glassblowing remains a highly skilled hand craft and the quality of glassware depends on the skill of each blower. Careful selection of the raw glass ensures that our final products are free from imperfections such as air lines, scratches and stones. You will be able to judge for yourself the workmanship of our glassware products. Safety All our glassware is annealed and made stress free to avoid breakage. Fax: +34 93 715 67 25 Scharlab The Lab Sourcing Group 3 www.scharlab.com Glassware Scharlau glassware is made from borosilicate glass that meets the specifications of the following standards: BS ISO 3585, DIN 12217 Type 3.3 Borosilicate glass ASTM E-438 Type 1 Class A Borosilicate glass US Pharmacopoeia Type 1 Borosilicate glass European Pharmacopoeia Type 1 Glass The typical chemical composition of our borosilicate glass is as follows: O Si 2 81% B2O3 13% Na2O 4% Al2O3 2% Glass is an inorganic substance that on cooling becomes rigid without crystallising and therefore it has no melting point as such. -
Environmental Chemistry Method Methoxyfenozide & Degradates In
Dow AgroSciences LLC Study ID: 110356 Page 12 Method Validation Study for the Detennination of Residues of Methoxyfenozide and its A-ring • Phenol Metabolite and B-ring Mono Acid Metabolite in Surface Water, Ground Water and Drinking Water by Liquid Chromatography with Tandem Mass Spectrometry INTRODUCTION J This method is applicable for the quantitative detennination of residues of methoxyfenozide and its A-ring phenol metabolite and B-ring mono acid metabolite in surface, ground and drinking water. The method was validated over the concentration range of 0.05-1.0 µg/L with a validated limit of quantitation of 0.05 µg/L. Common names, chemical names, and molecular formulas for the analytes are given in Table I. This study was conducted to fulfill data requirements outlined in the EPA Residue Chemistry Test Guidelines, OPPTS 850. 7100 (/). The validation will also comply with the requirements of EU Council Regulation (EC) No. 1107/2009 with particular regard to Section 3 of SANCO/3029/99 rev.4 and Section 3 of SANCO/825/00 rev.8.1 as well as PMRA Regulatory Directive Dir98-02 (2-4). The validation was conducted following Dow AgroSciences SOP ECL-24 with exceptions noted in the protocol or by protocol amendment. Method Principle Residues of methoxyfenozide, its A-ring phenol metabolite and its B-ring mono acid metabolite • are extracted from water samples by taking a l 0.0-mL aliquot and placing in an I I -dram (45-mL) glass vial equipped with a PTFE-lined cap or a 50-mL polypropylene centrifuge tube equipped with a cap. -

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. -

TEAM-USERS have shown a tendency in the past to - - neglect the boiler house for the engine room , and have concentrated their efforts for the improvement of the e ffi ciency of the plant almost exclusively upon the latter . A study of the losses incurred during the conversion of the thermal energy stored in coal into the thermal energy o f - steam , will show that it is in the boiler house that the greater preventable losses are occurring , and that the ratio ma y be expressed by the numbers 25 and 5. It is however , now beginning to be recognized that a s cientifically managed boiler-house is a sine quanon for the e i conom c generation of steam power , and considerable attention is being given by steam-engineers to this portion of their power generating plant . The chemical examination of the fuel , water, and of the waste gases has been found to be of great service in attain ing the highest efficiency from the boiler plant but no fi work has hitherto been published , at once scienti c and - practical , covering the ground required by the boiler house en lneer g . -
