Manufacturer: BYK-Gardner USA Brand: BYK-Gardner Model: 0645

The BYK-Gardner 0645 replacement bubble viscometer standard tube has a viscosity of approximately 1,737 centistokes (cSt), and is suitable for testing fluids such as resins and varnishes. The 9mL capacity sealed bubble tube standard is lettered Y and has a bubble test time of approximately 18.4 seconds. Sample fluid viscosity is determined by comparing bubble rise time to those of bubble tube standards and choosing the closest match. The sealed standard tube has a 15-year shelf life and can be National Institute of Standards and Technology (NIST) recertified. This bubble viscometer standard tube is ASTM International certified and meets the ASTM International D1545 standard for testing viscosity. 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 control applications. Some viscometers are manufa...

Manufacturer: isoSPEC Brand: isoSPEC

isoSPEC lamps are designed and manufactured to achieve all of the following fundamental requirements for a spectral line source. • Intense emission of resonance (ground state derived) lines. • Narrow line width, for maximum sensitivity and linearity. • Minimal spectral interference from continuum emission, present in the cathode. • Rapid warm up to produce stable long term light emission. • Noise free operation and long running life and a 5-year shelf life. • Cathode materials and geometry achieve a combination of spectral purity and a suitable sputtering rate. A high sputtering rate will give high intensity at the expense of lamp life, sensitivity and linearity. isoSPEC lamps have been tested and found to work as well as lamps sold specifically for SMITH-HIEFTJE background correction, however due to the high energy pulse used, some elements will be consumed at a higher rate reducing lamp life.

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.
