Questions and Answers

  • Is it worth the cost compared to cheaper models? | It depends on your needs. If you will use it irregularly or with small samples, perhaps a cheaper model is better. But with a longer longevity (and support) we expect our model to be cheaper in the long term. Having a greater wider range also allows you to expand your operations in the future without buying new equipment.
  • What does your support mean exactly? | We hate returns that aren't worth the hassle. If you have a problem in the first 2 years, we'll replace the unit or send you the broken part. Just let us know and we'll ship the unit immediately (generally 3-5 day shipping).
  • Is it complex to work with? | Not at all. It has intuitive controls and comes with PDF and print user manuals written by native English speakers.
  • Where is your company based? | Our management is based in the United States and our team is spread throughout the world.
  • I'm worried about the maintenance and upkeep costs. What's involved? |Nothing. The overhead stirrer has a maintenance (and oil!) free DC motor. If there are any problems in the first 2 years, we'll replace stirrer.
  • How long will it last? | The DC motor is rated for 10,000 hours (8 hours per day, 5 days per week for 5 years). With more intermittent use it can last for years.
  • Is it noisy? The motor is very quiet; significantly less than standard kitchen products.
  • Will it take up too much space? | All overhead stirrers are around 1.5 feet tall and a bit bulky. What makes ours stand out compared to some competitors is that we have a smaller benchtop profile. In fact, this instrument will take up less bench space than most (much weaker) magnetic stirrers.
  • Does it have the speed range suitable for my applications? | For most stirring applications, yes. The stirrer has a range between 100-2000 RPM.

Expanded Viscosity Range

Handle many substances not possible with magnetic stirrers.

Questions and Answers (continued)

  • Do I need any special vessels? | No. But the stirrer is design to work with larger quantities. If you try to use in small quantities, it will probably spill.
  • Does it overheat with continuous use? | If there is too much of a load, the motor will stop before overheating. That being said, we recommend using the stirrer for only 8 hours at a time to prolong the life of the motor.
  • Are replacement parts readily available and affordable? | Yes. If you have any problems with the paddle or stand we will replace it within the first 2 years. If you would like a different type of paddle they are readily available on Amazon. Just make sure that they are compatible with the 8-10mm chuck.
  • Is it easy to clean, especially after dealing with sticky or viscous substances? | Yes. The paddle is easily detachable (no tools needed with the chuck). The body of the stirrer is corrosion resistant and easy to wipe off with a cloth.
  • What safety features does it have to prevent accidents? | There is an overload function if the motor is put under too much of a load. The paddle moves at very high speeds so use an abundance of caution when handling the stirrer.
  • How precise is the speed control? | The overhead mixer is calibrated to 20 RPM increments between 100 and 2000 RPM.
  • Can it be customized to fit specific requirements of my experiments/production? The RPM is easily adjustable. If you need different paddle types, they are readily available on Amazon for around ($20-25). Just make sure they work with the 8-10mm drill chuck.
  • I haven't heard much about your brand. How do I know I can trust your products? | We've been in business since 2013 and are based in the United States. We have a reputation for honoring our after-product service (please check our Amazon reviews). If something goes wrong its very expensive for us so we are thorough with our quality control. Also, perhaps even more, we hate wasting people's time.
  • How easy is it to assemble or disassemble for cleaning or maintenance? The drill chuck doesn't require any special tools so you can remove the paddle in seconds. The rest of the assembly is easy to deconstruct and clean.
  • Is the stirrer portable enough to move around the lab if needed? Yes. It weighs around 20 lbs. but doesn't take up much bench space.

Our Support

If there is an unexpected problem, we will immediately replace any faulty unit or part for any reason within the first 2 years.

A Better Motor

The maintenance-free DC motor is rated to 10,000 hours (8 hours per day, 5 days per week for 5 years) and has an output power of 180 W (5X other popular overhead stirrers).

Questions and Answers (continued)

  • What are the tradeoffs between digital and analog models? | In general, digital models allow for a much greater degree of precisions. In particular, our digital model is significantly more powerful than our analog model (and top competitors). This allows for greater volumes and higher performance.
  • What are your quality control procedures? | Our factory is ISO-9001 and CE certified. We inspect each unit with a certified 3rd party inspection company as well.
  • Which voltage is this designed for? 110-240 V, 50 Hz (USA Plug with wide voltage range)
  • How important is precision with stirring? | It depends on your use case but is essential in the following situations: controlled stirring (maintaining constant variables); repeatability in experiments or recipes; scaling up or down processes; or working with (or avoiding) shear forces.
  • Which scale of work is this designed for? | Anything between very small samples to full-scale manufacturing.
  • How many stirring blades are included with this mixer? | The overhead mixer includes one stirring blade (pictured). The adjustable drill chuck is also compatible with most stirring blades with a diameter of 1-8mm.
  • Can I use the machine right out of the box? | Yes! The overhead stirrer can be easily assembled (no additional tools needed) in five minutes or less. This machine operates with a simple, intuitive design for fast and efficient use.

This is definitely an upgrade over my old overhead mixer, which was less than 150 watts. At 210 watts, this has enough power to mix even epoxies and other thick fluids. They don't include any photos of the back, but the back of the mixer is all solid cast aluminum with built-in heat sinks to dissipate the heat from running. The only reason I rated it 4 stars instead of 5 is...I don't know what the little clamp they include it supposed to do, but it really doesn't do anything. It could use a proper flask / beaker holder. But its certainly not necessary for it to do its job. Overall, I'm very happy with it. It sets up easy, is easy to operate, and has plenty of power.

What I like: Very easy to assemble. Convenient low to high speed levels, and speed dial moves very smoothly. Low noise level. Mixing is very powerful and gives good homogeneity.What I don't like: nothing. The mixer is worth its monetary value and great for starters.
