The white test paper turns blue upon application of cobalt ions (Co 2+ ). Interferences caused by iron or copper ions can be circumvented (see instructions for use supplied with the paper). Limit of sensitivity: 25 mg/l Co 2+Note: Non-destructive tests for the detection of cobalt in alloys are carried out as follows: apply 2 drops of acid solution (= 50 ml hydrogen peroxide 3 % + 7.5 ml o-phosphoric acid 85 % + 5 ml hydrochloric acid 37 %) to the degreased steel surface. After 30 to 60 seconds, absorb the liquid with the cobalt test paper. The presence of cobalt is indicated by a blue colour, the intensity of which varies according to the Co content. Limit of sensitivity: 0.5 %

Specific gravity hydrometers are commonly used in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Available in a variety of models measuring specific gravity / relative density (g/cmᶟ) of liquids lighter and heavier than water in various ranges from 0.690 to 3.000, they are made of lead free ballast and glass. These plain form hydrometers are individually serialized and have a temperature standardization of 60 degrees F (15 degrees C). DURAC Hydrometers are hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC/MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: Plain form hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.

Compex Easy Snap Performance Electrodes are used during muscle stimulation, and are compatible with all Compex snap-on cable devices. Electrodes are the points where the pulses are transmitted to your motor nerves, and ultimately your muscle fibers. They play a big part in the Compex muscle stimulation session, allowing you to work your muscle at peak effectiveness. Each Compex Easy Snap Performance Electrode is coated with a strong medical-grade adhesive, developed to stick to your skin. When used in normal circumstances, each electrode should last 15 to 20 sessions.

These test papers allow the qualitative determination of ions and chemical compounds. They are used to detect, if compounds tested for are present above a specific detection limit. Some of the papers have specific applications: Test papers for milk analysis: Peroxtesmo MI detects lactoperoxidase in milk. It is an accepted indicator to distinguish between raw milk and high heated milk. In contrast to liquid indicators based on guaiacol, Peroxtesmo MI does not smell and comes without hazardous reagents which is convenient and safe for the user. Phosphatesmo MI is used to detect alkaline phosphatase in milk. The test is suitable as a rapid test for successful pasteurization of milk.
