Tetrazolium salts are used in analytical chemistry as reagents for qualitative and quantitative determination of various compounds. These salts are also used in chemical kits for diagnostics of various diseases. The number of publications on analytical uses of tetrazolium salts is too large to be discussed in this chapter. Therefore, we direct the reader to surveys on preparative methods and properties of tetrazolium salts, where the use of these compounds in chemical analysis is also discussed C1990KGS1587, 1998RCR671, 2002RCR721>. 

Preparation of mouse Ig requires a minimum of 2 mL of mouse serum. A relatively simple technique for the preparation of total mouse Ig from serum, and one that gives adequately pure Ig for this test, is to use ammonium sulfate precipitation. Once the Ig is obtained and dialyzed against, e.g., PBS as used in ELISA, the concentration can be assessed either by protein estimation using chemical kits or, more easily, by reading the absorbance at 280 nm in an ultraviolet (UV) spectrophotometer. The concentration of Ig can be related to the absorbance using the following formula ...

Chemical kits describe any container housing small quantities of different chemicals used for medical, analytical, or testing purposes. The individual chemicals may exhibit one or more hazards, although they must be compatible with the other contents. First aid kits are convenient packages or boxes of medical supplies to provide immediate and sometimes makeshift medical attention. They may include multiple different materials, some of which will be hazardous (e.g., drugs, alcohols, mercury in thermometers) ...

Detector tube kits generally include a hand pump that draws a known volume of air through a chemically treated tube intended to react with certain contaminants. The length of color stain resulting in the tube correlates to chemical concentration. 

Polyesters. The main application of this material is as a matrix for glass fibre reinforcement. This can take many forms and is probably most commonly known as a DIY type material used for the manufacture of small boats, chemical containers, tanks and repair kits for cars, etc. 

The terms laboratory work and practical work are used in the literatrrre without precise defirrition to embrace mtmerous activities in science irrstructioa According to Hodson (1990), the term practical work means tasks in which students observe or manipirlate real objects or materials for themselves (individually or in small groups) or by witnessing teacher demonstratiorrs. In an extended sense, practical work involves not orrly work in the formal chemistry laboratory or demonstratiorrs, but also ar r type of activity that involves tangible objects, and provides students the opportrrrrity to manipirlate and interact with chemicals and observe chemistry in action corrsequently, home laboratory kits and computer simulations of experiments are also included. 

Recently there have been a variety of suppliers with chemical peel kits claiming ease of use and increased efficacy. These proprietary kits vary from the vehicle used in delivering the TCA to having color indicators to inform the physician of a peel s completion. Caution should be used when using such kits as many times the physician loses the ability to easily assess the degree of frosting and in turn the depth and safety of the chemical peel. 

Chemical spills in the laboratory may be hazardous, damaging to flooring and furniture finishes, or simply messy to clean up. Laboratory equipment houses and distributors of safety equipment carry a variety of clean-up kits made for specific types of spills, depending on the types of chemicals handled. Generally, the kits contain absorbents or neutralizers, or a combination of the two, plus instructions for use. Kits should be stored as close as possible to where spills are likely to occur and not in a remote storeroom. Instructions must be kept with the kits, not in a file cabinet. Quick action in case of a spill is important in reducing both hazards and damage.
