ONiLAB Electric Overhead Stirrer, LCD Digital Overhead Stirrer Mixer with Stirring Rod and Stand，Powerful 20L ，10000 mPas ， 50~2200RPM （Stand Included), Dark Blue……

Bought based on the reviews and it matched up to them. Sturdy base to mount onto and extended vertical post allowing lifting of mixer out of vessel without coming off the post. Setting the speed is easy and the allowance of the two different mixer types useful. One fixed four blade and the other with foldable blades which allow you drop into narrow opening containers then the centrifugal force once spinning throws them out to perform the mixing. Worked on a product which went very viscous > 5000cP, sped up to 1000rpm and still mixing. Would recommend as cheaper than alternatives, with no apparent downside.

Considering that alternatives are 5x the price. This tool does exactly what I need it too! Motor is nice and quiet too.

What a product, was sceptical because of the price and I thought might be some cheap Chinese product, very well packaged, strong sturdy unit with clear instructions, comes together in minutes no tools required, plug in and play - very powerful, perfect for my brewing lab, highly recommend

A sturdy, powerful, effective laboratory grade overhead stirrer. The stirrer is straightforward to set up once you know where each piece goes, either from looking at a picture of the assembled device or from the video in the online listing. It takes a little while to set up at just the right height for the container/project in hand. An Allen key is supplied for tightening the safety ring, which helps to make sure the main body of the machine doesn't slip downwards during use. Measuring jugs are to be obtained separately, so I used a Pyrex jug which I keep for non-food craft purposes. The speed of rotation can be varied from very low to very fast, with 2 different types of paddle - one straight and one with a cross-shaped head. Removing the measuring/stirring beaker is easy as, once the chuck is loosened, the rod is simply lifted upwards, and can protrude upwards out of a hole in the top of the machine to raise and lower it. The chuck is tightened/loosened by hand, requiring no key. A non-slip mat is supplied, to be adhered to the grey base, which is necessary as otherwise the force of the stirring can cause the measuring beaker to move on the base at high speeds. I ordered the stirrer after much thought, hoping it would be suitable for mixing resin and liquid silicone for making moulds, as I have difficulty stirring, especially for several minutes on end. Whilst the machine can do these things, it's designed for industrial, laboratory or school lab use, not for domestic settings. I don't work in a lab (just have a science degree from too long ago!). I tried a little silicone mixture which I had left over from a previous project, which even though it's viscous the machine stirred very well, however even working slowly with the paddles supplied there were air bubbles. Having since looked around, I think a paddle with a taller end/different shape is recommend for the purpose I had in mind, and the machine is very big, much more suited to a laboratory environment. It's also very heavy, especially the base, which is a really good thing to keep it stable even when stirring at high speeds. The base has non-slip feet and doesn't move at all. Spare parts for the stirrer can be purchased separately. Even though the machine is excessive for the purpose I had in mind, it's very well built, impressive in function and has been a privilege to use.

I bought this ONiLAB Electric Overhead Stirrer for my home brewing setup. It's decent for the price, but has some pros and cons. Pros: - Digital display is easy to read - Wide speed range is useful - Included stand is sturdy Cons: - A bit noisy at higher speeds - Controls take some getting used to - Stirring rod feels a little flimsy Overall, it works for my needs, but I'm not blown away. It's an okay choice if you're on a budget, but there might be better options out there if you can spend more.

I recently had the opportunity to use a lab mixer equipped with a brushless DC motor, and overall, I’ve found it to be a solid piece of equipment. The motor is maintenance-free and runs quietly, which is a big plus in a lab environment where noise can be a distraction. What really stood out to me is the motor's durability and precision—it's designed to work continuously for long periods, even up to a month, without issue. The plastic casing is tough and has good resistance to heat and flames, which adds an extra layer of safety. Using the mixer is straightforward. The drill chuck has a self-locking design, so you can easily attach or remove the stirring shaft without needing any tools. The "top-cross" design of the stirring paddle also makes it convenient to swap out containers without needing to take the shaft off, which saves time during repeated experiments. Plus, there’s a silicone cover that protects the drill chuck and motor from any corrosive vapors or splashes, which is great for extending the life of the equipment. The digital controls are another highlight. The microprocessor allows for precise and consistent speed control, even when the viscosity of the sample changes. The LED display makes it easy to monitor the speed, and the overload protection feature adds peace of mind, as the mixer will automatically shut off if there’s an issue. There’s also a safety circuit that turns off the unit in case of any abnormalities, which is reassuring. Overall, I’m very satisfied with this mixer. It’s reliable, user-friendly, and built with safety in mind. Given the manufacturer’s experience in lab equipment and the one-year guarantee, I feel confident in its long-term performance.

Running a laboratory-based, scientific business I was pleased to have the chance to test this item against the machines we normally use. Setting-up the stirrer and stand was straightforward and the quality of the components is certainly entirely adequate for everyday lab use. The stirrer motor is controlled by various press-buttons on the top and these have provided positive press inputs in use. The operational parameters do need to be input before the stirrer is activated - we have not found a way of modifying a cycle while the stirrer is actually operating. The range of stirring speeds is good (and settings are accurately maintained) - and the motor is quiet in operation and able to deal with viscosities up to a useful maximum of 10000mpas. During the week we have had this machine on test it has performed faultlessly. The base is heavy enough to provide adequate stability for all the tasks we have given it - and the motor and stirring mechanism has operated precisely according to our inputs. We even tested it stirring several thin resin mixtures and it completed those tasks with ease. Considering that the equivalent equipment in our lab costs 5x-10x the current price-point of this ONILAB stirrer, this offers very stable and capable performance... and it is easy to fully recommend this item at its current price point.

This is an ONiLAB Lab Analog Overhead Stirrer that can be used for up to 10L capacity. The stirrer comes with power supply, stirring unit PTFE Rod and main stand. Assembly of the unit is straight forward and will be setup in no time. One of the useful features here are the suckers on the rubber pads of the forged metal stand to make sure it stays in place and doesn't fall over. This stirrer offers 200-2500rpm Smooth and constant speed even at the cost of viscosity change plus as it is a single stable unit there will be no splashing. When running the unit it is very quiet which is useful in a busy office environment. The motor has Overload and speed protection with a safety circuit and so should be fine being left over night for extended work times. Overall this is a top performance and reliable automated analog stirrer.
