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. -
Laboratory Glassware N Edition No
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. -

No Description Pack Size 10048001 Q path Adhesive Slide white Box of 72 slides 10048002 Q path Adhesive Slide blue Box of 72 slides 10048003 Q path Adhesive Slide green Box of 72 slides 10048004 Q path Adhesive Slide yellow Box of 72 slides 10048005 Q path Adhesive Slide pink Box of 72 slides INTENDED PURPOSE These microscope slides may be used for the routine diagnosis of suspensions of cells and samples of tissue. 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. -
Uv and Visible Spectroscopy1
Page 1 of 4 I. INTRODUCTION TO UV AND VISIBLE SPECTROSCOPY1 When white light passes through or is reflected by a colored substance, a characteristic portion of the mixed wavelengths is absorbed. The remaining light will then assume the complementary color to the wavelength(s) absorbed. Thus, absorption of 420-430 nm light renders a substance yellow, and absorption of 500-520 nm light makes it red. Green is unique in that it can be created by absorption close to 400 nm as well as absorption near 800 nm. When sample molecules are exposed to light having an energy that matches a possible electronic transition within the molecule, some of the light energy will be absorbed as the electron is promoted to a higher energy orbital. An optical spectrometer records the wavelengths at which absorption occurs, together with the degree of absorption at each wavelength. The resulting spectrum is presented as a graph of absorbance (A) versus wavelength. Absorbance usually ranges from 0 (no absorption) to 2 (99% absorption), and is precisely defined in context with spectrometer operation. Because the absorbance of a sample will be proportional to the number of absorbing molecules in the spectrometer light beam (e.g. their molar concentration in the sample tube), it is necessary to correct the absorbance value for this and other operational factors if the spectra of different compounds are to be compared in a meaningful way. The corrected absorption value is called "molar absorptivity", and is particularly useful when comparing the spectra of different compounds and determining the relative strength of light absorbing functions (chromophores). -

Sulfur Dioxide
Corn Sugar (crude & refined) Analysis F-54-1 SULFUR DIOXIDE PRINCIPLE Sulfur dioxide is released by boiling an acidic sample solution, and it is removed by sweeping with a stream of nitrogen. The gas stream is passed through dilute hydrogen peroxide solution where sulfur dioxide is oxidized to sulfuric acid. The acid is titrated with standard alkali. (Note 1) SCOPE The method applies to crude and refined sugars (Note 2) and, with minor modification, to most liquid and solid samples even in the presence of other volatile compounds. SPECIAL APPARATUS 1. The FDA modified "Monier-Williams" apparatus (Figure 1) is available from Fisher Scientific, 91/92 Cat. No. K513800 (Kontes 513800), Pittsburgh, PA, and affiliates worldwide. It or some of its parts are also available from other laboratory supply houses. (Note 3) 2. Heating mantle, for a 1000 mL boiling flask, controlled by a variable transformer. 3.

General laboratory procedures All reactions requiring an inert atmosphere were performed under a blanket of nitrogen gas, which was dried through a column of phosphorus pentoxide. All commercially acquired chemicals were obtained from Sigma- Aldrich or Tokyo Chemical Industry, and were used without further purification unless otherwise stated. Anhydrous solvents were dried through an HPLC column on an Innovative Technology Inc. solvent purification system. NMR spectra were recorded on Bruker Avance-400 (1H NMR (400 MHz), 13C (100 MHz), 19F (376 MHz)) NMR spectrometers. Chemical shifts are reported in ppm (relative to the DMSO-d6 residual peak). IR spectra were recorded on a Perkin Elmer spectrum 100 FTIR using an ATR inset with a diamond crystal. -
