Digital based sensors hold calibration data and allow you to easily connect to any ProODO instrument. USB and communicatiosn saddle included. Soft and hard-sided carrying cases. Data management can become a daunting task over time but with the Data Manager software this task is much simpler and efficient. Download data, configure instruments, and conduct real-time studies easily with Data Manager software. View data graphically or in tabular form and export data as needed to other programs. Data Manager software is a very powerful tool. So powerful in fact, that we give it to you at no charge when purchasing a ProODO.

Manufacturer: BYK-Gardner USA Brand: BYK-Gardner Model: 8308

The BYK-Gardner 8308 EZ-series Zahn-type viscosity cup has a 10 to 60 centistokes (cSt) viscosity range and is suitable for testing fluids such as cements and other adhesives. Efflux times range 79 to 784 seconds. It has a metal body with a 12-inch loop handle for hand-dipping into a liquid container and a finger-ring for maintaining a vertical position during use. The orifice diameter is calibrated against National Institute of Standards and Technology (NIST) for testing standard oils. It includes an ASTM certificate. This Number 4 Zahn-type viscosity cup meets ASTM International D4212 standard for measuring viscosity using dip-type cups, ASTM D816 standard for testing rubber cements, and ASTM D1084 standard for testing viscosity of adhesives. A viscometer, also called a viscosimeter, is an instrument used to measure the friction caused by the relative motion of a Newtonian fluid and a known surface, and is usually expressed in units of poise (P), centipoise (cP), pascal seconds (Pa s), and millipascal seconds (mPa s). Viscometers have several forms, including but not limited to falling ball, rotational, vibrating, capillary, funnel, and bubble. A falling ball viscometer measures the time it takes for a ball of known diameter and density to fall through fluid in a cylinder of known diameter. A rotational viscometer measures the force required to stir a fluid. A vibrating viscometer measures the power input necessary to keep the oscillator vibrating at constant amplitude while immersed in a fluid. A capillary viscometer has a narrow-bore vertical section with two printed marks that measure time required for a known volume of fluid to fall a known distance. A funnel viscometer, such as a Ford, Zahn, or Shell cup, measures the time it takes a known volume of fluid to flow from the base of a cone through a short tube. A bubble viscometer measures the time required for an air bubble to rise through a fluid. Viscosity measurements are used in laboratories, research and development, process control, and plant quality ...

Manufacturer: Bibby Scientific Brand: Jenway Model: 060-254

The Jenway 060-253 glass fluorimetry cuvette has a path length of 10 x 10mm. This macro fluorimetry cuvette is used to take visible wavelength measurements from about 380 to 780 nanometers (nm). The glass is clear on four sides to take measurements at right angles.Cuvettes are specialized test tubes, used in laboratory or field research, to hold samples for optical analysis by instruments such as spectrophotometers, fluorometers, and turbidity meters. Their size or capacity is most often measured in milliliters or microliters. A cuvette may be cylindrical in shape, but square or rectangular cuvettes are used when light refraction must be minimized. A rectangular cuvette may have four clear sides, for use in a fluorometer, or only two clear sides opposite each other, for use in spectrophotometry. The path length of a cuvette, often given in millimeters or centimeters, is a measure of the distance that light travels through a sample in the cuvette. Cuvettes are made of transparent quartz, glass, or plastic. Each material offers different advantages: quartz is best in the ultraviolet light range, glass and plastic in the visible light range, and glass yields more precise results. Cuvettes may come with a cap for containment or a stopper for sealing. Cuvettes are also called cuvets, absorption cells, or sample cells.Bibby Scientific manufactures laboratory equipment such as shakers, centrifuges, incubators, and water baths under the Stuart, Jenway, and Techne brand names. The company is headquartered in Stone, Staffordshire, UK.
