There are two fundamentally different kinds of chemical bonds (covalent and ionic) that cause substances to have very different properties. The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. The molecular formula of a covalent compound gives the types and numbers of atoms present.
Almost any chemical requiring disposal is a hazardous waste which needs to be disposed of following the procedures listed in this handbook. Proper Handling of Chemical Hazardous Waste 1. A laboratory chemical becomes a waste when you no longer intend to use or reuse the chemical. It is at this point in time when the chemical must be managed as a
Clinical chemistry uses chemical processes to measure levels of chemical components in body fluids and tissues. The most common specimens used in clinical chemistry are blood and urine. Many different tests exist to detect and measure almost …
Components of a Basic Spill Kit. A chemical spill kit typically contains various components necessary for spill clean-up and containment. These include absorbent materials, personal protective equipment (PPE), spill control devices, and clean-up tools. Each component plays a crucial role in ensuring the safe and effective handling of a spill.
The process of chemical analysis consists of several steps, beginning with the taking of the sample and followed by sample preparation. The sample is subjected to the analytical method and we arrive at a result (Figure 1).
Components of PCR. The PCR reaction requires the following components: DNA Template : The double stranded DNA (dsDNA) of interest, separated from the sample. DNA Polymerase : Usually a thermostable Taq polymerase that does not rapidly denature at high temperatures (98°), and can function at a temperature optimum of about 70°C.

Around 6,000 years ago, laboratory medicine began with the analysis of human urine as uroscopy, which later became termed urinalysis. The word "uroscopy" derives from two Greek words: "ouron," which means urine and "skopeoa," which means to 'behold, contemplate, examine, inspect'. Ancient physicians spoke of urine as a window to the body's inner workings …
