Sugar Refractometer 28 ~ 62% Use this refractometer to test solutions with a higher sugar content, such as fruit juice concentrates, canned fruits containing added sugar, or ketchup as well as for egg yolk. Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever. All Sper Scientific refractometers come complete with: • Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat.• Covered eye piece and bright, clearly defined scale, with large easy-to-read measurements.• All the accessories for immediate use, including calibration tools and solutions, full instructions, transfer pipettes and protective cases. Dimensions: 6½" × 1½" (165 × 38 mm) Weight: 3.0 oz. (86 g) .

SpectroMembrane Thin-Film Sample Support Carrier Frames consist of a thin-film sample support substance attached to a frame that serves as a carrier. In affixing a thin-film substance to an XRF Sample Cup, the thin-film material is not directly handled and a contamination possibility is completely eliminated. Nearing or at the completion of attachment, the thin-film automatically detaches from the carrier frame leaving a taut wrinkle-free sample support window.

Made from optical quality polycarbonate plastic material, these plain form hydrometers are durable and shatterproof making them ideal in situations where rough handling or contamination could be an issue, such as in the food or beverage industries. Available in models measuring Baume of syrups and liquids heavier than water in various ranges from 0 to 31 degrees, these 255mm (10") long plain form hydrometers contain lead free ballast. Easy to read black scale on yellow back helps avoid eye fatigue. Each is individually serialized and has a temperature standardization of 60 degrees F (15 degrees C). DURAC Polycarbonate Hydrometers are made and 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. Made in USA. Note: Polycarbonate hydrometers are not recommended for use with petroleum-based liquids or other corrosives that would potentially affect the plastic material. They should be stored in a clean, dry, safe place and should not be subjected to extreme temperatures.
