If you’re short on time and you just want to find the best calorimeter, this short paragraph should help you get exactly the model you need. According to our research the Eisco Labs Food is the best because it is designed to be easy and convenient to use, and it also comes with a helpful guide. It’s lightweight construction ensures that it is easy for students to carry to class or the lab so they can begin to understand how energy related to food consumption. Since everything you need to get started, except food, is included with this kit it is also a great value for students on a budget. If the Eisco Labs Food is not available, your second option should be the American Educational Products Electric.

 

A.1 Best calorimeter

 

Whether you are studying to be a nutritionist or are looking for a scientific way to accurately measure the calories in your food, you need a specific kind of meter. A calorimeter measures the amount of energy released when food is heated so you can calculate the calories per gram. While this might sound a little complicated, in reality it is actually pretty easy. Before you rush out and buy one of these meters for home or school there are a few aspects to consider. In this buying guide you will find the information you need so you can confidently choose the best calorimeter in 2017.

 

Budget

As stated in the best calorimeter reviews one of the first aspects to consider is your budget, and this is true if you are a student or simply want one for use at home. There are several models to choose from and once you have decided on a set spending limit it will be easier for you to narrow down your possible options. One way you can save a little money is to avoid meters that come with a lot of extra features and functions.

While you can find calorimeters in a range of prices, you don’t want to try and save money by purchasing one constructed from inferior materials. The calorimeter will be used with heat, usually a flame or electricity, and one that is cheaply constructed can be dangerous to use. Not only can it be dangerous, but if it breaks after only a few uses it could become an expensive waste of money. This can also be true if you purchased one that is used.

 

Type

It is not uncommon for people to wonder what the best type of calorimeter is, and the answer usually depends on how it is going to be used. There are several types of calorimeters that use different methods but all measure the amount of heat emitted. Two of the most common types are the coffee cup and bomb calorimeter, and both come with their own advantages.

The coffee cup model is simple and inexpensive, and some students can even make one in the lab. All you really need is a styrofoam cup and a steady heat source to place it over. You will also need an instrument to measure the effect of the heat on the various liquids. While this type of meter is effective, it can only be used to measure small amounts at a time. If you are serious about determining the amount of energy released to determine precise calorie counts you will probably want to spend a little more on a bomb style meter.

You can often find these calorimeters in a variety of sizes and since the chamber is sealed and placed underwater it is often considered slightly safer to use. While these calorimeters can cost a little more, you can find some marketed as kits so everything that you need to get started is included for one fee. In some cases this can actually save you time and money since you don’t need to purchase additional accessories. For more precise measurements using specific methods there are also titration and scanning calorimeters, along with isothermal microcalorimeters. It should be noted that these types of meters are typically only found in a research lab, and may not be practical for all applications at home.

Other considerations

When you are looking for a calorimeter there are a few other factors to consider. The weight of the meter could be important, especially if you have to carry it to class. The same is also true for the size, though most calorimeters measure less than 8 inches tall. This ensures that not only are they relatively easy to take with you, but that the meters will fit on crowded counters and work desks. It is also important to note the power source, especially since not all models are electric. If you do choose one that is battery powered you will want to make sure that they are easy to replace as needed.

Since you will be working with heat you also want to calorimeter to be insulated, at least on the handle so you can safely lift the lid. You might also want to choose one that comes with a convenient thermometer or else this will be something that you might have to purchase separately. Since you are trying to measure the calories in specific foods, models that come with a built in cork and nail. This will provide you with a place to secure the small food sample so the reaction to the heat can be accurately measured.
