Job laboratory for chemical analysis of the sometimes quite complex and difficult, but at the same time it is important and interesting. Even when the technician solves the usual production problems associated with the analysis and control of incoming raw materials to the factory and finished products, using techniques developed by the chemical analysis of his action - the result of active mental activity.
In the laboratory work has an important place work related to preparation for analysis: to prepare the dishes, collect laboratory setting, to weigh, etc. In the modern factory chemical laboratories there are many different instruments of the newest, and they should be able to use the lab. And it requires him not only the knowledge, skills, and accuracy, precision, attention.
Laboratory technician should always strive to streamline their work. It is very important to organize the workplace: Do not clutter the table utensils, a small amount of reagents stored in special flasks, gently accustom ourselves to treat glassware. The purer the workplace, the more credible the results of the laboratory. An experienced technician is always covering beakers and cups with paper or watch glass of clean paper. This prevents the ingress of dust.
Experiments and tests appropriate to hold a minimum amount of material that reduces the execution time analysis, especially during operations such as filtration, distillation, drying, etc.
It is important to efficiently use their time. If for some reason the determination is delayed, we must start preparing for the next operation. For example, while the precipitate is dried in an oven, you can prepare dishes for the next operation. While the precipitate is centrifuged, laboratory prepares for the next batch of definitions, etc. But this does not mean that we should hurry. The rush for analytical work is very harmful.
In laboratory is no place monotony, though he cans every day to carry out analysis on the same methodology. However, he is constantly improving methods of analysis, using his experience and his comrades.
In analyst must be nimble hands and a sure eye. An experienced technician can almost not looking to take the required test tube, glass rod for stirring the solutions.
But this is only possible on condition that on the bench is always perfect order and everything is in place.
Laboratory work does not require great physical effort, but the nature of man, this profession is, of course, has specific requirements.
Each analysis requires painstaking precision work - and do not always get it right the first time. Therefore, laboratory must cultivate perseverance, patience, punctuality, attentiveness, punctuality. |
