![]() ![]() In other words, to increase the temperature, the bulb needs to emit more heat than the heat loss through the walls. ![]() The change in temperature inside the incubator is proportional to the amount of heat emitted by the tungsten bulb minus the heat loss through the walls of the incubator. On the most basic level, we are using a temperature sensor and a light bulb as our heating element. The goal of the incubator is to keep a constant temperature inside. In this instructable, we describe how to build a low cost (under 70$), yet accurate ( +/- 0.25C) DIY incubator using simple materials and some basic electronics components.Ī not-too-technical overview of how our incubator works. Given the higher price range of the commercially available incubators (upwards of several thousand dollars), non-professional biology enthusiasts might not afford to add an incubator to their stock of DIYbio tools. Our project contributes to the growing number of open source biology tools by developing a low-cost, yet relatively precise and easy-to-use incubator.Īn incubator is an essential tool for a number of biological experiments and is often used in bacterial cell culture experiments. These exciting developments pave the way for crowdsourcing biology research amongst students, hobbyists, and non-experts. Over the past few years, platforms such as OpenPCR and Pearl Biotech transilluminator have been designed to support biology work in schools and maker spaces for a fraction of the cost of professional lab equipment. This incubator is great for the Canvas Kit, where you can grow bacteria between 30-37℃, or the Yeast Canvas Kit, where you grow your yeast at 25-30℃ without problems.DIYbio, (Do It Yourself) biology is a growing movement that aims to make biology accessible outside of professional contexts. As you build and test this incubator, you will notice that the temperature can vary throughout the incubation period. It will only take a few minutes!Īs this is a simple DIY incubator, we recommend that you use this incubator to do experiments where keeping the temperature constant is not extremely crucial (more on that in a moment). Now that we know what incubators are and what they are used for, let's learn to build one! Follow the video below to build a simple incubator for Petri dishes using just a thermometer, lamp, and plastic containers. Interestingly enough, poultry or egg incubators are sometimes used to grow micro-organisms since the temperature range to hatch eggs and grow bacteria and yeast are similar. ![]() Of course, infant incubators will be more sophisticated than those you will use to grow micro-organisms, but will function under the same principles. That's right! When babies are born prematurely or when farmers want to hatch chicks, incubators are used to keep both babies and chicken eggs in an optimal environment for them to grow and thrive. There are three main types of incubators: poultry or egg incubators, infant incubators, and bacteriological incubators. An incubator is an insulated enclosure where temperature, humidity-and sometimes other environmental conditions like oxygen levels-can be controlled precisely. To control the temperature and humidity when growing micro-organisms on petri dishes, scientists use a piece of equipment called an incubator. After all, if the micro-organisms don't grow, you cannot complete the experiment! While some bacteria and yeast will grow if you leave them at room temperature, being able to control the environment in which they grow gives you a better chance of success and more reliable, repeatable results. Like us, organisms prefer certain conditions, like temperature and humidity levels, to grow in. Incubating (another word for 'growing') bacteria and yeast is often a crucial part of biotechnology experiments. Which kit is right for you?
