The role of a scientist varies dramatically over each school of science. Some scientists fight aging cells, look for ways to prevent cancer, partake in clinical studies and even duplicate DNA to learn more about the human body and its faults, as well as animals and other inanimate objects in the environment. Even though the science world is a complicated and intensive school of thought, here are five pieces of equipment every scientist uses.
1. Incubators are used in most science labs to chill or heat samples exactly, even at or near room temperature. There are many types, so be careful when shopping for a lab incubator. For example, one solid state convection chilling and heating incubator is a reliable and compact way to heat samples to 10 to 50 degrees Celsius. The other model has no compressors, which makes for an energy efficient device. This type of incubator will heat or cool samples anywhere from 4 to 70 degrees Celsius.
2. Digital or programmable hot plates and stirring hot plates are another staple found in a science lab to heat up samples. These types of hot plates are the most advanced and easiest to use. A popular model is the ECHOtherm Model HS40 and HS40A, which stores 10 routines with as many as 10 steps with the ability to automatically repeat each routine 1 to 98 times using the touch of a button. The ECHOtherm HP30 and HS30 are other models of digital hot plates that allow scientists to heat, stir and time the samples for accurate experimentation.
3. A variable speed rotating mixer is another standard device found in laboratories across the nation. The RT10 and RT11 models are some of the most popular styles and are designed to mix 0.5 and 1.5ml centrifuge tubes in an end over end motion and 15 and 50ml tubes in a horizontal rolling motion. This device also allows for the samples to move at speeds ranging from 4 to 40 rpm with the use of a single knob or button. Accessory racks are an accompanying feature that many scientists use with these rotating mixers to hold their samples and specimens.
4. A constant temperature chilling/heating mini circulator can also be found in many scientific laboratories. The ECHOtherm Model CB20 is a popular style and is used for chilling or heating at a constant temperature at a range of 4 to 70 degrees Celsius. The device can circulate a specimen up to 300ml per minute for controlling the temperature of small samples. The circulator uses a brushless mini-pump with a variable flow control for extracting the exact amount of temperature-controlled solutions. Scientists especially like these mini circulators because of its compact size and energy efficiency.
5. Handheld temperature meters and probes are another important asset to a science lab because of its digital, accurate and easy to use way of determining the temperature of a specimen. Some meters can read the temperature of something ranging from -50 to 650 degrees Celsius, or -58 to 999.9 degrees Fahrenheit.
