Finding the best magnetic stirrer with heating or without can be a daunting task nowadays as there are many options available for sale in today’s market and all should be considered. That’s why we’ve thought of giving a hand to prospective buyers by creating a comprehensive buying guide about magnetic stirrers and about how you can make the difference between a model you may need and one you can do without. Just keep reading if you want to make the right call.
The first detail you ought to give some thought to is the goal you are trying to achieve by utilizing such a product. You ought to look at the common jobs the device will have to perform and the type and volume of samples you will be utilizing. In addition, you may have to think ahead and realize whether you require the services of a magnetic stirrer without hot plate or if you would rather prefer the liquid becoming thinner on account of a higher temperature. It is rather tedious to have to warm up the sample separately and then start using the stirrer, especially as the liquid will inevitably chill out due to the movement.
Not all magnetic stirrers are made the same, and there are differences from one model to the next. Some products can mix a single beaker or a flask at a time, in just one position on the platform. By contrast, other devices are built to be more versatile yet also large because they can be used for mixing the contents of up to two flasks or more in either a single position or more. In the end, it boils down to the number of samples you want to process for every cycle as most of the units we’ve seen don’t offer too much space on the plate. Furthermore, it is important to note that bulkier models may take up a lot of space on your countertop or lab table.
If you work in very busy lab, maybe you might need a larger model due to the intense activity and requirements of your profession. On the other hand, while we were doing our research on the topic, we’ve noticed that magnetic stirrers are currently utilized by home users interested in preparing their own e-liquid. If you’re one of these prospective buyers, you may not need the assistance of a large magnetic stirrer unless you plan to make a business out of manufacturing and selling e-liquid.
Ease of use and convenience
These two are other factors to take into account when deciding to purchase one device or another. In this case, you have to look at the user-friendly features that the model has been equipped with. Ask yourself this: is it easier for you to utilize a digital readout or would you rather employ an analog controller? Besides, if a device with a hot plate is what you have on your mind, you need to analyze whether it pays off to focus on a heat sensor so that you’re able to monitor the sample temperature. We’ve also noticed that these days, models that can be connected to computers or laptops are amazingly convenient as they allow you to log the data.
It goes without saying that getting a unit from one of the top recommended magnetic stirrer manufacturers is a good idea, mostly because you’ll probably have no issues with warranties and getting in touch with customer support. If you don’t plan on upgrading or just replacing your magnetic stirrer every year or so, perhaps you have to focus on the warranty of the item. The maintenance requirements have to be considered as well, and here’s where some of the best magnetic stirrer reviews can help, because the opinions of other buyers should tell you what to expect from the product you might be thinking of purchasing.
