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.

The Hydrometer is an instrument which is constructed on the Archimedes principle that a solid body displaces its own weight of the liquid in which it floats. Hydrometers can be divided into two general classes; namely for liquids heavier than water and for liquids lighter than water. The base hydrometer scale is Specific Gravity, in which distilled water equals 1.000 as the initial point. Liquids lighter than water are scaled below 1.000 specific gravity and liquids heavier than water are scaled above 1.000 specific gravity. Hydrometers are usually calibrated at 60°F/60°F. To determine the density of a liquid, the liquid should be at 60°F. If the temperature varies, the liquid will either contract or expand, depending upon the temperature. Where there is a variation from the standard 60°F, corrections must be applied to the hydrometer reading. To assure proper corrections, a separate accurate thermometer should be used, or a hydrometer in combination with a thermometer, which is sometimes referred to as a "thermohydrometer." Internal Revenue Size R Alcohol Hydrometer. 185-206% Proof Range, 0.2% Subdivision, ±0.2% Tolerance, 305mm Length

Manufacturer: Thermo Scientific Brand: Oakton Model: WD-35462-15

The Oakton 35462-15 EcoTestr TDS High is a handheld, waterproof and dustproof pocket meter that measures TDS and floats, if dropped in liquid. A portable pocket meter is commonly used to measure the TDS of substance in aquaculture, aquariums, fish ponds, food processing, swimming pools, and in environmental treatment. This meter has ATC for accurate readings in fluctuating temperatures, and push-button calibration for a wide range of results. It features a transparent, protective cap to reduce contamination and protect the sensor. The cap keeps the sensor moist when stored upright, and can be used as a container for sensor-conditioning, or on-site calibration. The meter’s waterproof and dustproof housing has IP67-rating for protection against solid objects or liquids. Its stainless steel sensor tip is both durable and chemical resistant. The meter has a large, upright, single-line LCD screen for ease of viewing, a hold function which freezes readings for recording, and an auto shut-off to extend the life of the batteries. It has a click-lock battery cover for battery access to replace batteries without tools. The 35462-15 pocket meter comes with an integral stainless steel sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and operating temperature of 0 to 50 degrees C (32 to 122 degrees F). TDS factor is adjustable 0.4 to 1.0. TDS range is 0 to 10.1 ppt, resolution 0.1 ppt, accuracy + or - 1% full-scale (+ or - 2% above 5 ppt). Its dimensions are 1.25 (l) x 1.5 (w) x 6.5 (h) inches (3.2 x 3.8 x 16.8 cm) and it weighs 3.25 ounces. The testr works with four 1.5 V alkaline batteries (not included) for up to 500 hours of continuous use (Eveready A76 or LR44 replacements). TDS, such as salts and minerals, contribute to the conductivity of a solution. A TDS meter measures conductivity of a substance and converts it to a TDS reading. TDS readings are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, and water-testing and for scientific applications. ...
