Lab Vortex Mixer with Touch & Continuous Function Vortex Mixer Speed 200-3000rpm 4.5mm Orbital Diameter Lab Vortex Shaker

I must say, at first I really didn't like it but it slowly grew on me. The vortex is extremely powerful. It will definitely mix your solution so you don't have to worry about that. You have to make sure that you place this vortex on a flat surface. This is very important because since the vortex is very strong, and if the surface is uneven, the intensity of the shaking will cause the vortex to move on its own. I had to move it to another part of my lab where the counter was even.Second, at first, the user interface bothered me because once you turn it on, you cannot go directly to vortex your sample. Nothing will happen if you do this. You have to maneauver to settings and make sure to press the "touch/cont" button to begin the process in comparison to other vortexes that you just plug it in, turn it on and go directly to mix your solution. At first I didn't like this but I wasn't going to lower its star rating for this trivial manner, especially when I have used it a lot for experiments with success. It really has grown on me. Have been using it since April 2024. Lastly, I really love the time counter that it has (at least for the LED version). When you place the tube, it shows you how long you are vortexing and keeps track of the time. This is perfect for protocols, replication and teaching students for those very finicky solutions that are very hard to mix.One last tip: When you place the tube on the vortex mat, make sure you firmly apply pressure down because this particular vortex will not start unless you apply a certain type of strong pressure (this is if your using the "touch" option. As it name states, it will only start when you touch the tube surface mat.I also love that it brings different types of vortex mats for different volumes of tubes. I have it use so far for some hard-to-mix solutions on 1.5ml eppendorf tubes.Very well made vortex.

The media could not be loaded. I chose this item to use for mixing bottles of hobby paints because I'd seen a number of 3D printed adapters for vortex mixers, or projects to make paint mixers that were basically imitation vortex mixers. I really, really am glad I had the opportunity to add this tool to my hobby desk, because at my age shaking paint by hand goes from boring to painful pretty quickly and then means I don't paint because my hands and wrists hurt.Anyway, I've included a video or mixing a couple different bottle types using the included standard head. It does vibrate your hand quite a bit, so I'll probably 3D print an adapter just because some bottles need more time if they've settled a lot. It's also worth picking up some stainless steel ball bearings to drop in bottles of thicker paint like metallics. (This also helps if you're still shaking them manually.)In the video I'm using the Touch setting, which works well for short, quick mixes of more liquid paint. As I was testing on older, thickened paints I found that Continuous mode was easier for longer periods of time because I could shift my grip a bit and not have the mixer stop. Again - I'm not sure the vibration is something you want to subject your hands and wrists to for longer periods.I will say that it's not a perfect process, you need to check to see if the paint has begun to clump on the bottom of the bottle, break that up if it has, and mix for longer.Some of my paints are pretty old, and I'm always trying to reconstitute them enough to avoid buying new. I spent some time with this mixer and by using distilled water, a slow dry extender, a ball bearing, and blending with a palette knife - brought back a bottle of paint that was dried to a thick paste. Without this mixer to do the shaking, I would have just tossed it.Overall, now that I have experienced the benefits, I would recommended it to any painter who mixes bottles regularly, and definitely feel the mixer's value is worth the price.

I have used both the touch and continuous modes and both seems to do the job.Could use better vibration dampening on the bottom, as it there is quite a bit of 'walking'.

Has a few attachments that make it versatile and useful without having to have so much equipment inside the hood while working. It performs great and it is easy to use and set up. Great performance. Truly a must have in any lab.

The media could not be loaded. I've been wanting to try out a vortex mixer with my hundreds of hobby paint bottles that have settled over the years. When I ordered this LACHOI vortex mIxer, I didn't know what to expect, but WOW! This thing is built SOLIDLY.At first glance, it looks like the power half of a full sized drink blender. It weighs in at over five pounds. There is a master power switch on the back, and the single button on the front switches from "touch" mode (it activates when you press down); "continuous mode", that makes the plate move constantly, or "off." There is also a variable speed knob on the front right of the panel.And the machine is almost dead quiet!.I tested the machine with six different shelf aged hobby paints, for 40-50 seconds each, to see if they would reactivate the pigments. Out of the six, five were completely mixed and ready to use after using the vortex mixer. The sixth will need some added thinner and soaking time before I try to resurrect it again.This mixer comes with the small concave cup attachment, as well as a flat plate attachment, onto which either a padded rubber disc can be placed, or a test tube holder can be attached. When using the test tube holder, a screw is included to help attach the flat plate more permanently.I DID have a difficult time removing the flat plate. I pulled and pulled, and thought I was going to break the machine. But it did eventually loosen and remove, and I was able to install the concave cup again.This is a solid, high end, vortex mixer. I'm looking forward to using it to breathing new life into my wall of hobby paints again!
