The HI 96804 is a portable, water resistant digital invert sugar refractometer that employs the measurement of refractive index to determine the percent of invert sugar in aqueous solutions. 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 by weight concentration units. The meter features Automatic Temperature Compensation (ATC) between 10 and 40 degrees C (50 – 104 degrees F) and temperature (in C and F) is displayed 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. Range is 0 to 85%; 0 to 80 degrees C/32 to 176 degrees F, + or – 0.2%; 0.3 degrees C (0.5 degrees F) with a resolution of 0.1%; 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, and weighs 420 g. Invert sugar refractometers utilize the measurement of refractive index to determine the percent of invert sugar in a substance. They are used by researchers, manufacturers, and individuals. Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards. What’s in the Box?

The HI 99171N portable leather and paper pH meter has automatic calibration, on-screen tutorial messages, Automatic Temperature Compensation (ATC), a battery error prevention system, and a multi-level LCD screen. Calibration is automatic at one or two points with two sets of memorized buffers (Standard 4.01, 7.01, 10.01 or NIST 4.01, 6.86, 9.18), and calibration sachets are included. On-screen tutorial help aids in calibration and setup. ATC eliminates the need for extra calculations, and a built-in temperature probe measures pH and temperature simultaneously. The flat tip probe is specifically designed for direct pH measurement on paper and leather, and helps optimize surface contact with the sample. The meter has a battery error protection system to help prevent false readings, and a multi-level LCD screen with 3/8†black digits for readability. The meter is waterproof, and used for pH measurements of leather and paper, such as food industry packaging. pH range is -2.00 to 16.00 (+ or - 0.02pH), with a resolution of 0.01pH. Temperature range is -5.0 to 105.0 degrees C (23.0 to 221.0 degrees F), + or - 0.5 degrees C (up to 60 degrees C) and 1.0 degrees C (outside); + or - 1.0 degrees F (up to 140 degrees F) and 2.0 degrees F (outside) with a resolution of 0.1 degrees C (0.1 degrees F). Dimensions are 150 x 80 x 36 mm/5.9 x 3.1 x 1.4 inches (H x W x D), and it weighs 210 g (7.4 oz.). (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The device operates on three 1.5V AA batteries (included) and turns off automatically after eight minutes of non-use. pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.

Utilizing advances in microfluidic technology, the Gel Protein Recovery system has been developed to revolutionize the extraction of biomolecules, including proteins, peptides, and nucleic acids, from polyacrylamide and agarose gels. Proprietary developments in controlling electrokinetic flow have led to the development of a novel method for coupling high efficiency and robust electroelution with sample recovery decoupled from the electric field. The GPR-850 instrument delivers 500V per channel for rapid sample extraction, typically within 15 minutes. Each GPRchip contains an array of channels for processing up to 8 samples simultaneously. The combination of high voltage electroelution and the 8-plex GPRchip permit highly efficient sample recoveries with excellent throughput.

Nephelometric or transmittance measuring-the nephelometric measurement at 90° scattered light is advantageous for lower turbidity, whereas the transmission measurement at 180° is beneficial for medium to high turbidity values: With increasing turbidity, restray and scattering effects between particles are growing bigger. The reduction of light intensity in this case leads to a more accurate result than a 90° nephelometric measurement. Therefore, lab meters for high values are equipped with several measuring options: ratio modes calculate the final result from different measured angles. For ratiometric measurements, there is no specific standard method to be followed; rather, procedures are established by the application or industry. White light has a higher sensitivity for small particles, however, the inherent coloration of the solution has a stronger disturbing effect in this case. The IR measurement is required by DIN ISO, the white light measuring by US EPA.
