Manufacturer: MG Scientific Brand: MGM

The spectrometer consists of a telescope and a collimator mounted on a stable heavy C. I. base with three leveling screws. The protected 150 mm (6") or 175 mm (7)" scale divided into 0-360 degrees in steps of half degrees can be read from both scales & moves along with the telescope to give its exact position. It gives accuracy of one minute of an arc or 30 seconds of an arc. Telescope is having an achromatic objective of 7" focal length and a Rams den Eye Piece with cross line gratitude. The collimator is also fitted with 7" objective & adjustable precision vertical slit with jaws of non rusting metal. Both the telescope & collimator are having fine rack & pinion motion. In the center of the table there is a prism table for clamping of prism or diffraction grating. Packed in a sturdy wooden box with instruction manual & duster. L Available in Brass and Stainless Steel scale in both the sizes of 15.0 cm (6") and 17.5 cm (7") of protected circle.

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 ...

Students expect to use modern technology for just about everything they do these days. The RSpec-Explorer is light years ahead of traditional tools like diffraction gratings or electroscopes. Students will appreciate the ease with which they can digitally capture spectra, then study the results in real-time and all at the same time. The RSpec's live video captures the students' attention far more effectively than the passive activities often used today and the included camera and software make this an easy and inexpensive solution to studying quantitative spectral data in the classroom.

Manufacturer: Laxco, Inc. Brand: Laxco Inc Model: DSM-micro

The Laxco DSM-Micro cell-density meter has a 600nm wavelength single-beam LED light source to test for and measure yeast, E. coli, and bacterial cultures. The meter accepts 20&956;L micro-volume sample tubes. The meter measures McFarland units, % transmission, and absorption in either single-measurement or time-lapse mode. Time-lapse testing enables users to take readings at specified time intervals, and graphing allows data points to be displayed in a graphical format. The 3.5" LCD is backlit to ease reading, and has a 240 x 160 pixel resolution for displaying charts and graphs. Capacitive-touch buttons ease cleaning and prevent liquids from entering the device. The meter stores up to 2,000 data points that can be displayed in graph or chart format directly on the LCD. A USB 2.0 port allows the data to be exported to a PC for analysis or long-term records retention. The meter uses a 110VAC power source or can be operated using an internal rechargeable battery that enables the meter to be used away from power sources, including inside incubation cabinets, fume hoods, or under anaerobic conditions.

A spectrophotometer is a device used to measure and analyze aspects of light absorption in liquids and solids. Readings are displayed in digital or analog format. A spectrophotometer can have a handheld body for field use, or a bench-top body for laboratory applications. It may have one or more adapters to enable it to measure surfaces or liquids. A spectrophotometer is used for testing and measuring in anatomy, chemistry, agriculture, process plant, food and beverage making, homeland sec...

Manufacturer: Grand Index Brand: Grand Index Model: GI-PS01 Color: Black

The spectroscope is an important tool of the modern gemologist. This concerns the infrared or near infrared spectroscopes. A handheld spectroscope for visible light shows the absorption lines of the elements involved in producing its color. It helps to separate ruby (chrome) against red or pink sapphire (iron) to name only one example. This tool requires a good training and an appropriate light source. Colorless stones show no absorption spectrum. The sunlight shows a typical absorption spectrum, the Fraunhofersche lines. Fluorescence lamps show an emission spectrum. Fordemonstration you may examinate besides gemstones also liquids or flames colored by metal-salts. The model GI-PS01 is a prism type. It is composed of three optical grade glass prisms in optical contact with each other. It is equipped with adjust screw, the window can be focused.Ideal for demonstrations and quick laboratory observations, our easy-to-use, palm-sized instrument provides fast, accurate spectra from any visible light source. Features a precision lens and 3-element amici prism system housed in a stainless steel tube. Adjustable slip-type focus and optical slit. As slit opening diminishes, contrast decreases while resolution increases. Fits bar-type, holders for optical bench.
