Physical Chemistry Experiments on Microscale Shriniwas L Kelkar, Dilip D Dhavale and Jeevan G Chandwadkar It is evident from the earlier articles in this series that consider Shriniwas L Kelkar is a Reader in Organic able time and money can be saved if the academic laboratories Chemistry at University are to adopt microscale techniques.

After an active . research career and point regarding consumption of large quantities of chemicals publishing work on appears irrelevant from the physical chemistry point of view. heterocyclic chemistry, he is now devoting his Most of the experiments are already being performed with entire time and attention instruments and require per se small amounts of chemicals. to propagate the small scale experiments. On However, we felt that many of the traditional procedures should demand, he is available to be reviewed and rewritten to bring about not only further conduct workshops for training teachers on reduction in chemicals, time and energy but also bring theory microscale techniques. closer to the laboratories.

Phone: +52 5556 23 07 93 Received: 2013-12-31; Accepted: 2014-04-08 Abstract Biochemistry education requires laboratory sessions where theoretical knowledge may be put on test. At the same time, there is always some risk due to exposure to toxic materials, dangerous chemicals storage and waste disposal. Compliance with new regulations to prevent environmental contamination may also constitute a real hindrance for biochemistry teaching as experimental science. Therefore, we have designed microscale techniques, in order to reduce costs as well as the negative impact of laboratory practical sessions due to risk and environmental contamination. To develop microscale techniques does not only mean to reduce equipment size and amount of the reagents that are required for the usual experiments. Microscale techniques serve particularly well as a motivating approach to experimental biochemistry teaching that produces highly motivated students at the same time that requires minor costs and decreases working time, laboratory space, amount of reagents and dangerous waste. We have demonstrated all these positive effects in biochemistry teaching and prompted the formal implementation of microscale techniques into the formal activities from the Cell and Tissue Biochemistry Laboratory I (BCT-I) from the Chemistry, Pharmacy and Biology (QFB) curricula at the National Autonomous University of Mexico (UNAM). -

The US National Microscale Chemistry Center (Merrimack College, Massachusetts) was instrumental in the initiation of several centers. Its Mexican counterpart, the Mexican Microscale Chemistry Center (CMQM), has been a key player in this process. Other participating countries include Argentina, Bolivia, Brazil, Chile, Cuba, Guatemala, Perú and Uruguay. Key words: Microscale chemistry, laboratory, history of chemistry. RESUMEN Se ofrece un panorama del desarrollo de la química en microescala en América Latina. El Centro Nacional de Química en Microescala de los Estados Unidos de América fue clave para el inicio de varios centros.

Microscale Chemistry Involves Doing Experiments on a Small Scale
39th ChemEd Conference and 9th Annual BASF Summer School for Chemistry Teachers Using microscale apparatus for Leaving Certificate Chemistry Lab Practical work David O’Connell Christian Brothers College, Cork 17th October 2020 Aim of this Presentation To demonstrate how students can safely carry out chemistry practical work when working individually on some of the Leaving Certificate Chemistry mandatory experiments using microscale apparatus. What is microscale? Microscale chemistry involves doing experiments on a small scale. With the current COVID-19 pandemic restricting practical work in schools, microscale may be a useful alternative. Advantages of microscale includes: Less cleaning of equipment as most materials are disposable or easily cleaned Uses smaller quantities of chemicals and easy to assemble equipment Reduces sharing of equipment and need for students to move around the laboratory Less safety hazards compared to their macroscale equivalents Allows many experiments to be done quickly and sometimes outside of a laboratory Allows students to work independently using their own apparatus and equipment CLEAPSS Guidelines CLEAPSS GL352, p. 4 CLEAPSS GL352 – Managing practical work in non-lab environments (COVID-19 pandemic) CLEAPSS GL352 lists some microscale activities that can be carried out in non-lab environments. However, it points out that some activities should not be carried out in a non-laboratory environments, in particular those which involve heating. Examples of suitable microscale activities listed: PP019 - Analysis of vinegar by small-scale titration P001 - Investigating indicators on the CLEAPSS primary website. See CLEAPSS range of microscale activities by visiting their website. http://science.cleapss.org.uk/resources/resource-search.aspx?search=microscale Experiment videos Demonstration videos of these experiments done on a microscale will follow next.
