Designed for students from high school up to college, the spectrometer is used to make angular measurements during the study of physics, in particular an optical spectrum. This particular model is capable of showing the intensity of the light as a function of wavelength or frequency, with the light deflection capable of being produced by means of refraction using a prism, as well as by diffraction with a diffraction grating. Both a prism and a diffraction grating are included with this spectrometer. With its all-metal construction combined with a superb optical system, it is capable of providing years of high performance. It also features an easy to read scale, allowing students to measure the spectrum lines with a resolution of 50Å (angstrom). The telescope has a 7x magnification, and the scale features divisions that correspond to 100Å when the wavelength is greater than 5000Å, and 50Å when the wavelength is smaller than 5000Å. Other specifications include a 5.7° field of view, and a focal length of 130mm for the lens. The diffraction grating features 600 lines/nm, and the relavite aperture is 1:7.2. An instruction manual is also included, which contains a basic operating procedure and maintenance/storage instructions for the spectrometer.

The Calibration Control Kit eliminates the need for manufacturer calibration checks to save you hundreds of dollars per year. The rods should be measured in the luminometer on a regular basis to keep a record of calibration control.

Manufacturer: BYK-Gardner USA Brand: BYK-Gardner Model: 0663

BYK-Gardner bubble viscometers are used to quickly determine kinematic viscosity of known liquids such as resins and varnishes. The time required for an air buble to rise is directly proportional to the viscosity of the liquid - the faster the bubble rises, the lower the viscosity. BYK-Gardner bubble viscometers come in lettered tubes A5 through Z10 in four different tube sets covering viscosity ranges from 0.05 to 1,000 stokes.

The YSI 3059 standard flow cell allows sample collection and monitoring for surface and groundwater applications, such as in an aquifer or well, when used with the YSI 556MPS, 600XL, or 600XLM portable multiparameter meter, and single- or dual-parameter cables. The flow cell allows the probe to collect flow-through water samples for surface-water and ground-water monitoring. The unit can be mounted on a tripod, or pushed into the ground using the spike on the bottom of flow cell. For increased stability, it can be attached to a plate by using the brass insert and screwing it into the base. It can be easily disassembled for complete cleaning. The flow cell has two 1/4-inch and two 3/8-inch tube fittings (tubing and pump not included) as part of a set-up for flow-through water sample collection.A multiparameter meter is a benchtop or handheld device that can take multiple readings on a single sample. 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. The company, founded in 1948 and headquartered in Yellow Springs, OH, meets International Organization for Standardization (ISO) 9001 standards.
