μFocus targets give you a precisely formed dried droplet spot of predetermined size. You can work with larger (1700-2000 μm) spots and use standard spotting techniques. You can also work with much smaller spots (700-900 μm) that allow you to reduce the amount of matrix used, to maintain optimum matrix to analyte ratio with less concentrated or smaller analyte samples. Many users report 5-10x increases in sensitivity. Because μFocus spots are uniform, you also see improvements in spot-to-spot reproducibility, making quantitative analysis and fingerprint assays more reliable.

Fill Rite 901. FLOW METER 40GPM 1" PORTS

Manufacturer: Thomas Scientific Brand: BYK-Gardner Model: 115

The BYK-Gardner 115 flow cup has a 100 to 500 centistokes (cSt) viscosity range and is suitable for testing fluids such as paints and lacquers. The aluminum flow cup has a stainless steel orifice with a 4mm diameter. Efflux times range from 20 to 110 seconds. This DIN flow cup includes an International Organization for Standardization (ISO) 2431 certificate and is calibrated against Physikalisch-Technische Bundesanstalt (PTB) for testing standard oils. 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 manufactured to meet industry or governmental standards, including Ingress Protection (IP), National Institute of Standards and Technology (NIST), International Standards Organization (ISO), and ASTM International (formerly American Society for Testing an...
