Manufacturer: Bel-Art Brand: SP Scienceware Model: B61801-5500

Specific gravity hydrometers are commonly used in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Available in a variety of models measuring specific gravity / relative density (g/cmᶟ) of liquids lighter and heavier than water in various ranges from 0.690 to 3.000, they are made of lead free ballast and glass. These plain form hydrometers are individually serialized and have a temperature standardization of 60 degrees F (15 degrees C). DURAC Hydrometers are hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC/MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: Plain form hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.

Manufacturer: Grand Index Brand: Grand Index Model: ZGRA-100ATC

ZGR series has its own light source. With the built-in light source, it makes more convenient to use when in a Dark or Dim room or when doing wide-field work.And it also can use the outside light source to test. It is convenient to replace the batteries when they were use out.The models have only one unit system: °F. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems.And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids.The ZGRA-100ATC has Automatic Temperature Compensation System. Guarantee: Offer 2 years warranty Specification: Measuring Range: Ethylene Glycol: -84°F-32°F 0--70% Propylene Glycol:-60°F-32°F 0--63% Battery Fluids:1.100-1.400sg Resolution Factor:5°F,5°F, 0.01sg (ATC)Temperature Compensation Range:10°C-30°C Power Require: 3 “ " Button Cell (1.5V*3) Battery Life: More than 100hours Light Source: White LED Dimension: 27x40x160mm

A Simple and Quick Method for Determining Aqueous pH Between 5.5 and 8.0

Manufacturer: Scientific Equipment of Houston Brand: SEOH

QUANTOFIX test strips are semi-quantitative in nature. They meet all requirements for a modern rapid test. Most of the QUANTOFIX test strips can be carried out in 10-120 seconds. That makes the application very quick for the end user. All QUANTOFIX tests are ready to use kits. They are precalibrated and contain all necessary equipment and reagents. As "labs in a pocket" they are very handy for the end user. The color charts are adjusted and checked using certified standard solutions that are directly traceable to primary NIST standards. The user can be sure to receive accurate readings whenever he tests. Make sure to store the packs in a dry, cool place at 39-86 °F (4-30 °C). Some tests are separately marked to require cool storage at 39-46 °F (4-8 °C). To ensure the longevity of the test strips, please close the tube immediately after removing a strip. The desiccant in the stopper effectively protects the strips against moisture. The strips can safely be used up to the date printed on the pack. The initial shelf life of the QUANTOFIX products is 2.5 years after production. Strongly or weakly acidic solutions have to be buffered with solid sodium acetate prior to testing, since the test paper does not react with sulphites in acidic media. Sulphide ions interfere since they also produce a red reaction colour of the test paper in neutral solution. This interference can be eliminated by the addition of an excess of nickel(II) ions. The NiS formed can be removed by filtration. Larger amounts of reducing agents, such as hydroxylammonium chloride or ascorbic acid, interfere, causing low sulphite results.
