The selection of refrigerated incubators is perfect for storing samples in a controlled environment. These reliable instruments are available in various sizes and offer refrigeration, CO2 control, water jackets, gravity convection, and precise digital controls.
Cooled incubators provide stable, refrigerated conditions for conducting lab research, including BOD determinations, bacterial culturing, and water pollution testing. They feature robust refrigeration systems and programmable microprocessor controllers with alarms.
Breaking Barriers 2023 will showcase the incredible work being done by individuals and organizations to promote diversity and inclusion.
Temperature
The temperature of a refrigerator is an essential factor in the science incubation process. If it is too cold, bacteria like listeria can spawn and cause problems.
For this reason, it is best to keep your refrigerator at a temperature between 35 and 37 degrees. That way, you will not cross the 40oF threshold that could harm your samples.
There are several types of refrigerated incubator available for use in laboratory settings. These vary by the space they fill, their storage capacity, temperature range, and whether or not they have alarms for when the incubator goes outside the set parameters.
Cooled incubators offer precise temperature control and have air circulation fans to provide fresh air inside the chamber. They may also contain different sensors that monitor the temperature. They are used in biology and microbiology laboratories. BOD incubators (biological oxygen demand) are used for growing yeast and molds in the laboratory at a low temperature of 20 to 25 deg C.
Humidity
The humidity of a refrigerator has an essential effect on the science incubation process. Eggs and microtitre plates tend to dry out during incubation, which is why it is necessary to maintain a suitable level of humidity in your incubator.
Relative humidity can be measured by wrapping a wet cotton cloth around the bulb of a thermometer and suspending it in the hatching compartment. Due to evaporation, the wet-bulb temperature will be lower than the dry-bulb temperature and can be converted to percent relative humidity using a psychrometric table.
Humidity levels should be maintained between 58-60 percent or 84-86o F., wet-bulb, and increased to 65 percent or more when hatching occurs. It ensures that the egg is not dehydrated and that the hatchlings can reach their full developmental potential.
CO2
Science incubator maintain an environment in which biological or cell cultures are grown. They achieve these conditions by controlling temperature, humidity, CO2 concentration, and pH levels.
Controlling these conditions is vital because it allows technicians to create ideal growth environments for the species being researched. Incubators also need to be able to detect when the conditions go out of balance and automatically alert users or technicians when this happens.
There are a few different methods to measure CO2 concentration in an incubator. One approach is to detect changes in thermal conductivity (TC).
Another method uses an infrared sensor. Both ways can detect changes in the CO2 content of an incubator chamber.
Regardless of the method used, it is vital to choose a CO2 sensor that is advanced and calibrated. It will ensure the sensors can provide the accurate and precise data you need.
Controls
Controls are an essential part of the refrigeration process, and you will find several types of controls available on our refrigerators. Some more popular varieties include dial knobs and rocker switches, but other types are becoming increasingly common.
One type of control is mechanical, which requires users to physically manipulate the knobs and buttons to change settings or activate a feature. This type of control has been around for decades and is still used in commercial refrigeration equipment, but it is also being introduced into more and more kitchen appliances.
Other controls include monitoring systems that help operators set and maintain their incubation temperatures. Some incubators even have CO2 sensors, which monitor the level of carbon dioxide in the air.
