ONiLAB Digital Linear Shaker Adjustable Speed 40-200RPM, Capacity 2KG, Linear Shaker with Continuous Model(Set time to Zero) or Timer Mode, LED Display Speed and time, Labs and Classrooms

I have what most would consider a "typical" lab shaker, with the adjustable rails to hold things in place, like Erlenmeyer flasks...but where as that shaker excels at shaking things that stand up, but doesn't do shaking things that lie flat very well, for obvious reasons...this shaker from ONILAB excels at shaking things lying on their sides, but isn't that great at shaking things that stand up, because of the elastic band hold-down. So, each shaker type performs a specific function well, and the other one not so well. So ideally, you want one of each. This is an excellent "flat bed" style shaker. It's VERY smooth, very quiet, and is a piece of cake to use. If you're looking to add a shaker to your laboratory arsenal, this is a good choice. I also recommend you look at the "cage style" shakers, too. I find owning one of each quite handy, you might also. Amazon sells both kinds. 5 stars.

I gave it 3 stars because it does what it's supposed to do. Yet there's 3 issues that are really annoying. 1 - anytime you press any button, it emits a loud beep. I mean, annoyingly and unnecessarily loud. Maybe it's OK if it's only being used in a hospital or medical environment. There's no way to turn it off or turn down the volume on it. This is extremely annoying since I use this inside the house. The wife and my dogs hate it as well as I do. 2 - the instant you turn it on, the moving tray does a very fast and sudden jerk movement. Which means, to avoid getting hit by it on your arm while you're reaching for the power switch, you need to come at the power switch from the side or over the top of the unit. That's the only way to turn it on without the tray slamming into you when you power it on. 3 - while it's running, it makes an annoying motor hum that changes pitch up and down as the tray is doing it's tilting. Kind of sounds like a muffled cat being swung around and around. But I will say that it does its job.

It is pretty simple lab equipment, Mine has been running for months now for agitating liquid medium. It operates smoothly and noiselessly. Lab equipment can be so expensive, With this price, It has a powerful motor, great digital control, slow ramp up, and a heavy-duty power supply. Everything about it was perfect!

This is an excellent digital orbital laboratory shaker. When I worked in the research laboratory many years ago before retiring we used a shaker but it wasn’t digital and not as nice as this shaker. This shaker comes with two bands to secure items that can be secured. The speed is easily adjustable between 40 and 200 revolutions per minute (RPM). This is an excellent range of speed on a shaker. It is small and doesn’t take up a lot of space. The work platform has a non-slip rubber mat that is also easy to clean. The bottom also has rubber so it stays in one place and doesn’t move while in motion. The housing is solid plastic which I would rather have than the old-fashioned metal ones that were not friendly to work with. This will be a pleasure to use. I will update my review if anything changes.

This is a fairly run of the mill linear shaker for use in a laboratory environment. The device worked as described for the small amount of time I've had it in use, but given how these shakers are used in a lab, I haven't had time to put it through any real trials. I found the build quality to be adequate, it's not flimsy and cheap feeling, but it also doesn't scream quality. It is on par with it's price point. The device is not really compact or small, it takes up quite a bit of bench space, but that may be required given the weight capacity. In either case, if I needed another lab shaker I would consider buying this in the future.
