Manufacturer: Thermo Scientific Brand: Oakton Model: WD-35608-51

The Oakton 35608-51 is a conductivity/Total Dissolved Solid (TDS) electrode, with cell constant of K=10.0 for high-range conductivity measurements. The electrode, also known as a probe, measures the conductivity and TDS of a solution, and is commonly used in testing water, such as pure and sea water, in field and laboratory applications. This probe features platinum sensors for specific use, epoxy-body housing for impact-resistance, and durability, and to reduce air bubble entrapment. It comes with a removable, plastic probe guard to preserve the electrode. The 35608-51 electrode has a temperature range of 0 to 80 degrees C (32 to 176 degrees F), and it is used for high-range conductivity measurements. Its dimensions are 100 (l) x 12 (d) mm. It is intended for use with the Oakton CON 400, and meters that have 5-pin Deutsches Institut für Normung (DIN)-connections (sold separately). It comes with a 3-foot cable. An electrode is used with a meter to measure the parameters of a substance. Conductivity is the ability of a solution or material to conduct an electrical current. TDS measurement indicates materials, such as salts, bases or minerals, which contribute to electrical conductivity, within a solution. Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses. Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

Manufacturer: Vee Gee Scientific Brand: Vee Gee Scientific Model: BX-50

BX-50 Handheld Refractometer, 0-50% Brix 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), Urea and NaCI. A

Manufacturer: Sper Scientific Brand: Sper Scientific Model: 300002C

Sugar Refractometer 28 ~ 62% Use this refractometer to test solutions with a higher sugar content, such as fruit juice concentrates, canned fruits containing added sugar, or ketchup as well as for egg yolk. 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 Certificate of Calibration.

Microporous Film is a gas permeable membrane that enables the analysis of non-volatile liquid and powdered sample substances in helium flushes or vacuum. Pressure differentials within the sample cup and sample chamber are equalized while maintaining a taut thin-film sample support plane. The Series 1500 XRF Sample Cups are designed for use with Microporous Film. One of two supplied Snap-On Rings included with the 1500 Series Sample Cups is used to attach Microporous Film to the Cell neck of the open end of the sample cup nearest the outer integrated flange. The sample cup Cell is designed with the unique "bead-to-indent" geometry that creates taut thin-film sample support planes and effective seals against leakage. The second included Snap-On Ring is used to affix a thin-film sample support window to the opposite open end of the sample cup. In practice, the illustrated assembly procedure is reversed. The thin-film sample support is attached first enabling one or more sample cups to be conveniently filled from the top end; Microporous Film is attached last. Microporous Film is also available in Easy-to-Use Precut Circles for elimination of trimming and convenience of attachment to Chemplex XRF Sample Cups.
