In addition to performing routine tasks under the direction of scientists, many technicians also develop and adapt laboratory procedures to achieve the best results, interpret data, and devise solutions to problems. The increasing use of robotics to perform many routine tasks formerly done by technicians has freed technicians to operate other, more sophisticated laboratory equipment. Agricultural technicians work with agricultural scientists in food and fiber research, production, and processing. Some conduct tests and experiments to improve the yield and quality of crops or to increase the resistance of plants and animals to disease, insects, or other hazards. Other agricultural technicians do animal breeding and nutrition work.
Biological technicians work with biologists, studying living organisms.
They may assist scientists who conduct medical research, helping to find a cure for cancer or AIDS, for example. Those who work in pharmaceutical companies help develop and manufacture medicinal and pharmaceutical preparations. Biological technicians also analyze organic substances such as blood, food, and drugs, and some examine evidence in criminal investigations. Biological technicians working in biotechnology labs use the knowledge and techniques gained from basic research by scientists, including gene splicing and recombinant DNA, and apply these techniques in product development. Chemical technicians work with chemists and chemical engineers, developing and using chemicals and related products and equipment.
