Measurement of Gas volumes in Laboratories

Measurement of gas volume contributes to studies on reaction rates and commercial viability of chemical and biochemical processes in which a gas Is a by-product. Additionally measurement of volumes of vapours are also required for determination of molecular weights of volatile liquids by Victor – Meyer method. Measurement of volumes of liquids in comparison is […]

Laboratory Cryogens and their uses

Cryogens are materials with boiling points below which find applications in laboratories requiring extremely low temperatures. Such materials boil well below room temperature and on sudden exposure to room temperature can result in uncontrolled boiling. Cryogenic materials require special handling, storage and transportation. For common laboratory applications a vacuum jacketed dewar is sufficient. A loose […]

Differences between Primary and Secondary reference standards used for analytical work

Any chemical analysis can be considered valid only if the method of analysis is validated before adoption and results are reported against internationally recognized standard reference materials. Results of such analysis can be relied upon by consumers as well as other laboratories across the world. Standards are primarily used for the following types of analytical studies: […]

Essential considerations in moisture determination by Karl Fischer titration

Presence of moisture plays a vital role in deciding characteristic properties and stability of pharmaceutical and food products. Merits and demerits of water determination methods have been covered earlier. Karl Fischer is the preferred method adopted by most laboratories due to its high specificity and selectivity towards water present even in traces levels in a product. […]

Can analytical instruments be operated continuously without breaks?

Increasing sophistication has contributed to impressive growth in automation in analytical laboratories. Automation in turn leads to increase in laboratory productivity and frees the operator to attend to other laboratory tasks. User-friendly application software of most instruments enables easy setup of operational parameters and permit unattended overnight runs. Robotic arms of auto samplers work in […]

Training program on basic analytical techniques and microbiology testing was held from […]

Safe Handling of Laboratory Instruments

Sophisticated analytical instruments have become essential necessity in modern day research and industrial laboratories. Such instruments provide benefits of high accuracy of results and time saving due to their capability of handling large number of samples in the limited time available. However, such instruments require safe handling as they present potential hazards of electrocution,exposure to […]

Essential measures for prevention of harm from laboratory chemicals

Laboratory chemicals offer a diverse range of hazards to laboratory workers and need to be handled with extreme care. Exposure to such hazardous materials becomes inevitable but adherence to safety guidelines can prevent such exposure and minimize the resulting harm. The earlier article How laboratory chemicals gain entry into your body discusses the four common groups […]

How laboratory chemicals gain entry into your body?

Laboratory chemicals are found commonly as solids, powders, gases, fumes and liquids. Your body is vulnerable to harm through exposure to chemicals when you work in laboratories. The extent of harm can depend on the level of exposure and individual tolerances to allergic reactions of such materials. In your school days a lab coat was […]
