  • Laboratory Equipment Used in Filtration
    KNOW YOUR LAB EQUIPMENTS Test tube A test tube, also known as a sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Beakers Beakers are used as containers. They are available in a variety of sizes. Although they often possess volume markings, these are only rough estimates of the liquid volume. The markings are not necessarily accurate. Erlenmeyer flask Erlenmeyer flasks are often used as reaction vessels, particularly in titrations. As with beakers, the volume markings should not be considered accurate. Volumetric flask Volumetric flasks are used to measure and store solutions with a high degree of accuracy. These flasks generally possess a marking near the top that indicates the level at which the volume of the liquid is equal to the volume written on the outside of the flask. These devices are often used when solutions containing dissolved solids of known concentration are needed. Graduated cylinder Graduated cylinders are used to transfer liquids with a moderate degree of accuracy. Pipette Pipettes are used for transferring liquids with a fixed volume and quantity of liquid must be known to a high degree of accuracy. Graduated pipette These Pipettes are calibrated in the factory to release the desired quantity of liquid. Disposable pipette Disposable transfer. These Pipettes are made of plastic and are useful for transferring liquids dropwise. Burette Burettes are devices used typically in analytical, quantitative chemistry applications for measuring liquid solution. Differing from a pipette since the sample quantity delivered is changeable, graduated Burettes are used heavily in titration experiments.

  • Visco Handbook THEORY and APPLICATION of VISCOMETRY with GLASS CAPILLARY VISCOMETERS Welcome to SI Analytics!
    Visco handbook THEORY AND APPLICATION OF VISCOMETRY WITH GLASS CAPILLARY VISCOMETERS Welcome to SI Analytics! We express our core competence, namely the production of analytical instruments, with our company name SI Analytics. SI also stands for the main products of our company: sensors and instruments. As part of the history of SCHOTT® AG, SI Analytics has nearly 80 years experience in glass technology and in the development of analytical equipment. As always, our products are manufactured in Mainz with a high level of innovation and quality. Our electrodes, titrators and capillary viscometers will continue to be the right tools in any location where expertise in analytical measurement technology is required. In 2011 SI Analytics became part of the listed company Xylem Inc., headquartered in Rye Brook / N.Y., USA. Xylem is a leading international provider of water solutions. We are pleased to introduce you to the Visco Handbook! It replaces the previous brochure "Theory and Practice of Capillary Viscometry". This has been updated, redesigned and restructured. The information content of some areas such as polymer analysis was increased and specially themed areas such as hydrodynamic principles were moved into their own appendices so as not to deter the reader by too much theory. The focus was placed on the practical and general information needed by each user of capillary viscometry. Both laboratory experiences and policies of the relevant standards are considered here. We thus hope to provide you with a faithful companion for everyday laboratory work, one that you can use profitably. We of SI Analytics are pleased to work with you successfully in the future.

  • Tests of Instruments for the Determination, Indication, Or Recording of the Specific Gravities of Gases
    U. S. DEPARTMENT OF COMMERCE W. AVERELL HARRIMAN, Secretary NATIONAL BUREAU OF STANDARDS E. U. CONDON, Director NATIONAL BUREAU OF STANDARDS MISCELLANEOUS PUBLICATION M177 TESTS OF INSTRUMENTS FOR THE DETERMINATION, INDICATION, OR RECORDING OF THE SPECIFIC GRAVITIES OF GASES By FRANCIS A. SMITH, JOHN H. EISEMAN, AND E. CARROLL CREITZ Issued January 20, 1947 UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1947 For sale by the Superintendent of Documents, U. S. Government Printing Office Washington 25, D. C. - Price $1.00 PREFACE At the request of the American Society for Testing Materials, a critical study was made of the commercial instruments for the deter- mination of the specific gravities of gases. Eleven different instru- ments were studied with the use of 15 test gases of known specific gravities. Determinations were made of the accuracy and reproduci- bility, of the effects of changes of temperature, relative humidity and water content of the surrounding air, and of sources of error and applicable corrections. It is believed that the results herein presented will be of considerable value to those requiring accurate data on the specific gravities of gases. E. U. Condon, Director. ii TESTS OF INSTRUMENTS FOR THE DETERMINATION, INDICATION, OR RECORDING OF THE SPECIFIC GRAVITIES OF GASES By Francis A. Smith, John H. Eiseman, and E. Carroll Creitz ABSTRACT At the request of the American Society for Testing Materials, the National Bureau of Standards completed in 1941 a critical study of instruments available to industry for the determination, indication, or recording of the specific gravities of gases. Instruments were submitted for test by all interested manufacturers.

  • THE STOICHIOMETRY of ANCIENT METALLURGY Materials: Ring
    THE STOICHIOMETRY OF ANCIENT METALLURGY Adapted by: MIDN 1/C Justin Dion Materials: Ring stand (2), tripod stand, clay triangle, small porcelain crucible with lid, Bunsen burner (2), malachite chips, granular (“fish bowl”) charcoal, crucible tongs, forceps, striker, weighing boat Ref: Yee, Gordon T.; Johnson, Chris E. J. Chem. Educ. 2004, 81, 1777-1779 Purpose: The purposes of this experiment are: (1) To prepare elemental copper through the techniques used by Stone Age men circa 3000 B.C.E; and (2) to trace the stoichiometry of a 2 step reaction through percent yield determinations at each step. Learning Objectives: 1. Master the proper and most effective use of a Bunsen burner 2. Understand basic stoichiometry and be able to calculate the expected and % yield of each step of a reaction 3. Recognize and appreciate the historical aspects of metallurgy and apply them to a contemporary laboratory environment Pre-lab: Complete the pre-lab questions before lab. Discussion1: Technological advancements were for thousands of years the outcome of accidents. The greatest discoveries of the Stone Age period were driven not by a desire for scientific data, but rather by the activities that were part of everyday life for the ancient man. Stone Age men were drawn to naturally occurring materials that were aesthetically pleasing. They searched for strong, durable materials that could be used as tools. They also searched for materials that could be used as jewelry or as works of art. Around 3000 B.C.E, Stone Age men were drawn towards malachite, a bright green mineral that was abundant in the cliffs and hillsides that surrounded them.
