Attention is invited to the Line of Chemical Glass Ware of our own manufacture. By purchasing this class of goods at home, instead of depending upon foreign sources of supply, the carrying of a large and expensive stock is avoided; the opportunity of effecting changes in the form of apparatus for special purposes is afforded, and promptness in filling orders greatly facilitated. Under the advice and direction of experienced chemists, we have for a number of years been perfecting our work in these lines, and now feel confident that the character both of the glass and work manship will be found, for all the usual needs of the Laboratory, to compare favorably with the imported wares. -

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. -

Cynthia Bolon 213 Schrenk Hall [email protected] 341-4439 OBJECTIVES: Course objectives are to develop facility with performing laboratory techniques involving the handling of organic chemicals safely and the keeping of proper records of experiments conducted in the laboratory. Crystallization, distillation, extraction and chromatography are emphasized as separation and purification techniques. Melting points, boiling points, and refractive indices are used routinely as measures of purity. Safe handling of chemicals and proper disposal of waste products are priority goals in this course. To help in attaining such goals, the first week of the semester is devoted to SAFETY in the chemistry laboratory. For the remainder of the semester, most of the experiments are conducted on a micro scale.

Given that the possibilities for their use are highly varied, these glass slides should only be handled by users who hold a professional qualification that complies with national legislation. These microscope slides are intended for single use only. Any re-use or inappropriate treatment of their surface could lead to inaccurate results, the deterioration of preparations, and erroneous diagnoses. WARNING AND PRECAUTIONS Before use, please read all this information carefully. Microscope slides and cover slips are intended for single use by qualified personnel. They must under no circumstances be used more than once, and must be disposed of after use or at the end of the archive period in an appropriate manner as potentially infectious waste. If you observe any damage to the packaging, or any signs of glass fragments, the slides and cover slips must not be used, due to the risk of injury from glass splinters. Recommendation: In order to reduce the risk of injury due to sharp edges as much as possible, we strongly recommend the use of our microscope slides with polished edges. -

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. -

The Stoichiometry of a Reaction Introduction This Experiment Provides a Method to Determine the Mole Ratio in Which Two Substances Combine Chemically
The Stoichiometry of a Reaction Introduction This experiment provides a method to determine the mole ratio in which two substances combine chemically. Such information is helpful in determining the stoichiometry of a reaction, i.e. the balanced chemical equation and the information that can be derived from it. The principle underlying this experiment is based on keeping the quantity of one reactant constant while varying the quantity of a second reactant. The mass of the precipitate produced is then used as an indicator of the effect of varying the quantity of the second reactant. When enough of the second reactant has been added to completely react with the first reactant, there will be no further increase in the amount of the precipitate produced, regardless of how much of the second one is added. Equipment/Materials 0.1M Pb(NO3)2 Stirring rod 0.1M KI Funnel 5 % HNO3 Side-armed Erlenmeyer flask Filter paper Hot plate 10mL automatic pipets Analytical balance 50 mL beakers Wash bottle of DI water Safety • Goggles must be worn at all times in the laboratory. • Pour any leftover solution in the designated containers. • Follow your instructor’s directions for the disposal of the precipitates. Guiding Questions Which trial(s) will give the most precipitate? Why? 9A-1 Procedure 1. In this experiment the stoichiometry of the lead nitrate – potassium iodide system will be investigated. The volume of the potassium iodide will be held constant while the volume of the lead nitrate is varied. The concentration of both solutions will be 0.1000 M. Each lab group will be asked to prepare two combinations in the following table.
