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.

Manufacturer: Dwyer Instruments, Inc. Brand: Dwyer

Dwyer® Series WM2 Multi-Jet Water Meter is ideal for commercial and industrial applications. The multi-jet design allows for simplicity and accuracy with wide flow ranges, even in low flow applications. The magnetically driven, hermetically sealed register will not leak or fog and is completely separated from the water. These water meters are designed for long service life and maintenance-free operation, even under harsh conditions. Note: NOT FOR POTABLE WATER USE, BRASS CONTAINS LEAD IN EXCESS OF LOW LEAD LIMITS. (Standard range shown in picture).

Manufacturer: Vee Gee Scientific Brand: Vee Gee Scientific Model: SX-1

SX-1 Handheld Refractometer, 0-10% Sodium Chloride VEE GEE X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution. Includes Carry Case (1 ea.) Plastic Transfer Pipet (1 ea.) Instruction Manual (1 ea.) Features Largest Sharpest Display Scale Available Exclusive Zero-Ring Requires No Calibration Tools Durable, All-Metal Design Easy to Use. Operation consists of placing 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the readings. Accurate. Featuring the largest, easiest-to-read scale available with clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy even when several different operators use the instrument. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors. Compact Portable. The small size of the X-Series models allows them to be used anywhere the field, plant, or lab. Tool-Free Calibration. The VEE GEE exclusive Zero-Ring eliminates the hassle of using a separate tool for calibration. Simply place a few drops of distilled water or liquid standard (R.I. oil or prepared sucrose solution) on the prism, turn the built-in Zero-Ring until the shadow line is at the correct value of the liquid, and secure the set screw that's it Durable. The X-Series models feature rugged construction to provide years of reliable use. The prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Also feature non-roll stands to ensure that once the units are placed on a table or bench top, they won't be prone to roll off the surface. Wide Selection of Scales Ranges. Choose from Brix, Salinity, Refractive Index (nD), and Coolant (freezing points of Ethylene Propylene Glycol, Battery Charge Level). Automa

Manufacturer: Sper Scientific Brand: Sper Scientific Model: 300006C

Salt Refractometer 0 ~ 28% Measures salt content in sea water, pickling-brines and other applications. While the scale is calibrated for sodium chloride, it can also be used for calcium chloride, barium cobalt, magnesium, cesium, potassium, sodium chloride, cupric sulfate, potassium iodide, citric acid, acetic acid and (vinegar).Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever. All Sper Scientific refractometers come complete with: • Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat.• Covered eye piece and bright, clearly defined scale, with large easy-to-read measurements.• All the accessories for immediate use, including calibration tools and solutions, full instructions, transfer pipettes and protective cases. Dimensions: 6½" × 1½" (165 × 38 mm) Weight: 3.0 oz. (86 g) Comes with a Certification of Calibration.
