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).

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96831

The HI 96831 is a portable, water resistant, digital ethylene glycol refractometer that utilizes the measurement of refractive index to determine the percent volume and freezing point of ethylene glycol based coolants or antifreeze. The meter helps eliminate the uncertainty associated with mechanical refractometers, and is suitable for field or lab use. Samples are measured after a simple user calibration with deionized or distilled water and within 1.5 seconds the instrument measures the refractive index of the sample and converts it to percent volume or freezing point. The meter features Automatic Temperature Compensation (ATC) between 0 and 40 degrees C/32 – 104 degrees F, and temperature is displayed (in C and F) simultaneously with the measurement on a large, dual-level LCD display along with icons for low power and other message codes. Auto-shut off feature turns the meter off automatically after three minutes of non use. Volume % range is 0 to 100% + or – 0.2% with a resolution of 0.1%. Freezing point range is 0 to -50 degrees C (32 to -58 degrees F) + or – 0.5 degrees C (+ or – 1.0 degrees F). Temperature range is 0 to 80 degrees C (32 to 176 degrees F) + or – 0.3 degrees C (+ or – 0.5 degrees F) with a resolution of 0.1 degrees C (0.1 degrees F). The device operates on a 9V battery. Dimensions are 19.2 x 10.2 x 6.7 cm (H x W x D), and weighs 420 g. Ethylene Glycol is an organic compound commonly used as an automotive antifreeze, and a precursor to polymers.

Manufacturer: ATAGO U.S.A.,Inc. Brand: Atago Model: 2313

The Atago 2313 MASTER-M is a hand-held, portable, water-resistant refractometer with a Brix scale that measures in the 0.0 to 33.0% range, has a spoon-shaped tip for automatic smooth sampling (ASD), manual temperature compensation, and a ridged outer shell. A Brix refractometer measures the refractive index of a solution in a sample, converts it to sugar concentration in units of percent by weight (% Brix, also known as degrees Brix), and displays the results. Hand-held refractometers, also known as sugar meters, concentration meters, or Brix meters, are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications. This refractometer is housed in a durable, die-cast aluminum metal body for heat and organic solvent resistance. The 2313 MASTER-M features manual temperature compensation. The unit can be calibrated with water. Calibration can be controlled and adjusted with an exposed calibration screw and an included specialized screwdriver, although other items can be used to unscrew the unit. However, the unit retains its water-resistance. A spoon-shaped tip allows for automatic sample distribution (ASD) across the prism and boundary line (also called measurement line) for accurate, smooth sampling with small portions, and sample disposal from the edge. With ASD, the daylight plate does not need to be lifted to cover the prism with the sample. The outer shell grip is smooth and easy to clean, which reduces the possibility of food and sample entrapment, avoiding contamination and bacterial growth. The analog Brix scale features a bright, high-contrast display for clear visibility of the boundary and memory lines intersection. Samples are viewed through a monocular, focusable, cushioned eyepiece. The unit includes a protective plastic storage case with a foam cut-out insert to cushion the instrument.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96813

Digital refractometer for measurement of sugar in wine (percent brix and (percent v/v). Quick, accurate results, readings are displayed in approximately 1.5 seconds. Single point calibration with distilled or deionized water. Small sample size, can be as small as 2 metric drops. Automatic shut-off after three minutes of non-use. Stainless steel sample well, easy to clean and corrosion resistant. ABS thermoplastic casing. This optical instrument employs the measurement of the refractive index to determine parameters pertinent to the wine industry. The actual measurement of the refractive index is simple and quick and provides the vintner a standard accepted method for sugar content analysis. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds, the instrument measures the refractive index of the grape must. These digital refractometers eliminate the uncertainty associated with mechanical refractometers and are ideal for fast, reliable measurements in the field. The HI 96813 allows the user to tailor the instrument to their specific needs based on their experience, since no fixed conversion factor is universally applicable. The first conversion is based on the percent brix value and an adjustable conversion factor between 0.50 and 0.70 (0.55 is a common value). Potential alcohol (percent v/v) = (0.50 to 0.70) x percent brix. One drawback of the above equation is that it does not take into account the nonfermentable sugars and extract. A second equation was also added that takes these factors into account and can give a more accurate estimate of the alcohol content in the finished wine. This conversion is named "C1" on the meter, and uses the following equation: potential alcohol (percent v/v) = 0.059 x [(2.66 x degree Oe) - 30] (C1). HI96813 is supplied with battery and instruction manual.
