What is Science Laboratory Technology?
- The SLT program focuses on the fundamental principles of biological and physical sciences, emphasizing analytical laboratory techniques and applications, specifically in chemistry and biology.
Science Laboratory Technology
- Scientific investigation involves exploration of the environment and unknown to develop relevant hypotheses to establish its validity or otherwise.
- A laboratory is a setting where scientific information and principles are tested and theories are tried out.
- Laboratories are equipped with necessary tools and items.
- Laboratories are organized based on the requirements of the specialists working within them. A physics lab may include a particle accelerator, a metallurgy lab might have metal casting equipment whereas a biologist's lab could have wet labs, and one for computer scientists will have computer equipment for analysis of data.
Laboratory Technology Goals and Objectives
- Assisting in chemical analysis within educational institutions, food and chemical industries, research institutes
- Assisting in biological experiments within institutional laboratories, farms, museums, and other establishments.
- Assisting in physics experiments in educational institutions and industries.
- Supervising laboratories in educational institutions,
- Assisting in scientific warehouse organization and management.
- Assisting in the marketing and distribution of scientific equipment and consumables.
Laboratory Equipment and Supplies
- Equipment includes tools such as Bunsen burners and microscopes, in addition to other specialty equipment
- Laboratory glassware (Beaker, reagent bottle)
- Autoclave, Microscope, centrifuges, shakers, mixers, pipettes, analytical devices (e.g., HPLC, spectrophotometers)
- Thermal cyclers (PCR), photometer, refrigerators and freezers, universal testing machine, ULT freezers, incubators, bioreactors, biological safety cabinets, sequencing instruments, fume hoods, environmental chambers, humidifiers, weighing scales.
- Reagents and polymer supplies (consumables for µL and mL scale, mainly sterile).
- Other tools and equipment will vary based on the type of lab.
Laboratory Safety
- Laboratories contain potential hazards, including poisons, infectious agents, flammable, explosive, or radioactive materials, moving machinery, extreme temperatures, lasers, strong magnetic fields, and high voltage.
- Safety procedures and equipment are used to minimize risks.
Laboratory Sustainability
- Efforts to reduce energy consumption and implement waste sorting processes will create a greener work place.
- Fume hoods, because of their large energy use, can potentially be impacted by adjusting their usage when not in use to maintain minimal energy use.
Weighing Scales
- A scale or balance measures weight or mass.
- Traditional scales use two plates or bowls suspended and use known weights to balance an unknown weight.
- Spring scales use the extension of a spring.
- Some scales calibrated to measure force (weight) and some measure mass in Kg or lbs.
Pan Balance History
- Ancient Egyptian records include illustrations of scales.
- Evidence of weighing scales dates back to the 4th Dynasty of Egypt.
- Uniformly sized stones were used to represent an amount.
- Weighing scales were used in ancient civilizations.
