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.

Manufacturer: Cannon Instrument Brand: CANNON Instrument

The Cannon ZCAC-RO-9 Zeitfuchs cross-arm viscometer has a permanently attached 51mm diameter round metal holder and a 6,000 to 30,000 centistokes (cSt) viscosity measuring range. It is suitable for the measurement of either transparent or opaque Newtonian fluids such as fuels and lubricants. It uses a viscometer constant of 30 centistokes per second (cSt/s) for calculating kinematic viscosity of sample sizes as small as 1.0mL. The ZCAC-RO-series size 9 viscometer uses a 230mm depth water bath (not included) for temperature-control testing and a vacuum (not included) to draw a sample up for timed testing between two sets of printed marks. It includes an ASTM International certificate of calibration. This calibrated capillary-style viscometer meets the ASTM International D446 standard for viscometers and the D445 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 ...

Manufacturer: Eisco Brand: EISCO Model: PH0619

The Eisco PH0619 laboratory-grade goniometer-type spectrometer has 0 to 360 degree rotation, 1 degree graduations, and a 0.1 degree vernier scale to provide hands-on experience observing and measuring light spectra. The collimator is mounted on a spring-loaded support, integral with the base. The collimator tube has an adjustable slit on one end and an achromatic converging lens with a 178mm focal length on the other end. The lens is secured in a tube that can be hand adjusted to ensure the slit is in the focal plane of the lens to produce parallel rays. The collimator scale has a 170mm diameter and 0 to 360 degree rotation at 1 degree intervals. It is capable of independent rotation and has a locking screw. The prism table is mounted on a 175mm diameter circular degree scale. The scale is rotatable around the central axis and is provided with a clamping screw. The prism table has three leveling screws and marked lines to assist with precise placement of the prism (sold separately). The astronomical-type telescope is mounted on heavy bearings, and can be rotated around the central axis of the apparatus. It consists of an achromatic objective at one end, and a Ramsden eyepiece with crosswires at the other end. The position of the lens can be hand adjusted. A clamping screw allows the position of the telescope to be fixed, and a tangent screw provides fine adjustment. A vernier scale allows the position of the telescope to be read to a precision of 0.1 degrees. The body and structural parts of the spectrometer are comprised of heavy castings to provide precision and durability. The spectrometer weighs 10.9 lb. and is 11 x 12.2 x 16.5 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use ...

It measures parameters such as the pH level (acidity or alkalinity of a substance), conductivity (the amount of salts or other compounds present in water), dissolved oxygen (DO, the amount of oxygen in a liquid), temperature, total dissolved solids (TDS, anything present in water other than the pure water molecule and suspended solids), salinity, resistivity, and oxidation reduction potential (ORP). Applications for multiparameter meters include water testing, pharmaceuticals, agriculture, winemaking, water-treatment plants, and aquaculture. Devices with a benchtop body are often used for indoor laboratory use or in a manufacturing setting; handheld, portable devices are typically used for fieldwork. Sensors are used with a meter to measure the parameters of a substance.YSI is a manufacturer of sensors, instruments, software, and data collection platforms for environmental water quality monitoring and testing.
