Cryogenic Technology
Cryogens are substances (liquids or fluids) usually at very extreme low temperatures (below –150 °C, –238 °F or 123 K). Cryogenic technology can be defined as the study of the production of low temperature fluids, measurements at low temperatures, and behavior of these materials at low temperature and how to produce them. It is also concerned with the application of low temperature processes and techniques

Photographic Technology
Photography simply means writing, drawing or printing with light. Light is therefore most fundamental in photography because without it then no photographs will be produced. Light is a form of energy, it’s a source of all colors and its composed of different wavelengths, those that are of importance in photography are those that fall within the visible region of the electromagnetic spectra because they can be perceived by the human eye. These are composed of different colors e.g. red, blue green yellow orange etc.

Laboratory Inspection
The laboratory inspection is the safety audit of the conditions and operations that occur on a daily basis in a specific laboratory. Laboratory inspections are conducted at least annually to ensure safety and compliance with all applicable lab safety regulations and guidelines. These inspections are also intended to provide a formal opportunity for laboratory personnel to ask questions regarding any aspect of lab safety in order to improve overall compliance. Laboratory inspectors need to have a greater understanding of safe laboratory operations. The lab inspector needs a higher level of laboratory safety training to be able to recognize problem areas and be able to ask questions and eliminate the hazards.

Cleaning Reagents for Special Obstinate Stains

The most common cleaning reagents for obstinate stains include

  1. Chromic acid
  2. Aquaregia

(i) Cleaning using chromic acids

Chromic acid is a very corrosive solution prepared by weighing out 10 g of sodium dichromate crystals, make it into a slurry with a few mls of water, then dissolve in 250mls conc. sulphuric acid with stirring and cooling (ice-bath), to give a thick syrupy dark brown mixture.

 After preparation, fill the container with chromic acid solution and allow it to stand for an overnight, pour away the acid and thoroughly rinse the apparatus with distilled water and allow it to dry.

Burets and Pipettes should be left standing in chromic acid solution in a tall plastic cylinder.

(ii) Cleaning using Aquaregia

Aquaregia is prepare by mixing one part by volume of conc. Nitric acid with three (3) parts by volume of conc. Hydrochloric acid in a Pyrex beaker and allowing it to stand until a bright red color develops.

Aquaregia is used for removing organic stains.

  1. These reagents are very corrosive, fuming and poisonous, they must be prepared in a fume chamber and protective clothing must be worn when handling them
