Manufacturer: Thermo Scientific Brand: Barnant Model: GV-2300

The Barnant GV-2300 falling ball viscometer includes two size #3 balls of different densities for measurement of the dynamic viscosity of transparent Newtonian fluids. It uses a glass ball for the 20 to 200 centipoise (cP) range and a 316 stainless steel ball for the 100 to 1,000cP range. An optional tantalum ball (sold separately) measures the 200 to 2,000cP range. The viscometer uses a 7mL sample size and the closed system allows testing highly evaporative and hydroscopically deteriorative solutions. It has wetted materials of glass, Viton, and Delrin acetal for corrosion resistance. This falling ball viscometer is suitable for testing a variety of fluids used in laboratories, research and development, process control, and plant quality control applications. 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, an...

Manufacturer: BYK-Gardner USA Brand: BYK-Gardner Model: 0620

The BYK-Gardner 620 replacement bubble viscometer standard tube has a viscosity of approximately 268.2 centistokes (cSt), and is suitable for testing fluids such as resins and varnishes. The 9mL capacity sealed bubble tube standard is lettered J and has a bubble test time of approximately 2.75 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.

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.

Measure the viscosity of liquids such as paint, lacquer, oil, and syrups. Simply insert the cup into your sample and lift the viscosity cup out, starting a stopwatch/timer. Cup is made of series 400 stainless steel and requires 44 mL of sample for the test. After withdrawing the cup, measure the time it takes until the first break in the liquid stream. A conversion sheet is supplied that will convert the Zahn time to a centistokes value. Cup includes an NIST-traceable calibration report supplied by the manufacturer to meet your quality program requirements. Simple and convenient — no complicated training needed.
