Safe storage practices for chemicals in laboratory refrigerators

Laboratory chemicals are stable only within prescribed temperature limits. High purity chemicals used as reference standards require preservation in low temperatures so that the concentration of active constituent does not change over their prescribed usage life. Flammable liquids also require to be stored under low temperatures so as to prevent formation of explosive vapours over […]

Safe operation of a laboratory centrifuge

Filtration of the precipitate from supernatant solution used to be a common laboratory practice in earlier days. The operation was simple to carry out as it involved only pouring the solution gently over a tilted glass rod held against folded filter paper fixed inside a glass funnel .However, the process was time-consuming and took your […]

Laboratory respirators and their maintenance

The laboratory environment requires control through proper humidity and air ventilation and carrying out all hazardous operations in fume hoods. At times, however, you may have to work on highly toxic, poisonous, carcinogenic materials or harmful bacteria and viruses. In such situations make use of laboratory facemasks to prevent breathing intake of such potentially dangerous […]

What you should know about fighting laboratory fires?

Laboratories hold potential risk of fire accidents due to presence of flammable materials. Fire hazards in the laboratory covers groupings of flammable liquids, solids and gases and also advocates need for fire insurance to recover losses due to fire accidents. Understanding nature of Laboratory Fire Hazards A majority of fire accidents in laboratories can be avoided […]

Safe handling practices for laboratory Cryogens

Cryogens are essential requirements in research and analytical testing laboratories . They help improve the sensitivity and resolution of some analysis techniques to levels which are not achievable at room temperatures. However, there are some hazards associated with their use. Some safe handling suggestions are provided in the current article which will help avoid laboratory mishaps. Transportation […]

Hazard potential of laboratory Cryogens

Liquid nitrogen and liquid helium are two common cryogens found in laboratories housing sophisticated analytical instruments. Both exist as harmless gases at room temperature but have very low boiling points. Nitrogen has a boiling point of and helium has a still lower boiling point of which is just 4 degrees the above absolute zero temperature. Such […]

Useful Tips on safe use of laboratory heating devices

Heating is an essential requirement in laboratories for carrying out common operations such as: Purification of solvents by distillation Extractions using rotary evaporators Studies on kinetics of chemical reactions Determination of physical parameters such as boiling point, melting point, flashpoint, etc Sample digestions Drying of cleaned glassware for subsequent use Drying of precipitates or determinations […]

How to Prevent Accidents through safe handling of analytical instruments

Analytical instruments are capable of producing results with high degree of accuracy and precision. As a consequence analytical techniques are widely superseding the earlier classical methods. However, such instruments are prone to accidents and hazards arising from carelessness in handling them. Apart from hazards breakdowns result in loss of productivity and additional expense in repairs. […]

Which is the best available option for storage of Laboratory Chemicals?

Which is the best available option for storage of Laboratory Chemicals? On entering any laboratory you will come across chemicals and reagents stocked on workbench platforms and sidewall shelves. Have you ever wondered as to what would be the ideal plan for storage of chemicals. The available options are: Unplanned Random storage Alphabetical sequence Storage […]

How good hygiene practices contribute to laboratory safety and quality of results?

Hygiene is essential in all workplace environments. It assumes even greater significance in laboratory as both safety and quality of results are in direct relation to standards of personal hygiene. Laboratory safety measures undoubtedly contribute to an accident free environment but good hygiene practices supplement it with higher productivity and health of laboratory workers. Good Housekeeping […]
