ONiLAB's Scientific Mini Centrifuge 7000RPM, 2680 x g RCF, Lab Benchtop Centrifuge with 2 Rotors for 8 x 0.2/0.5/1.5/2.0ml and 0.2mL×32 PCR Strips, Low Noise≤45dB, 100-240V((ONLY for MICROTUBES)

I recently purchased the ONiLAB Scientific Mini Centrifuge, and I have to be honest. I sat there staring at it wondering what to do with a Centrifuge.So I got to googling and did some fun experiments! After separating beer, oil and water, and making some strange concoction called pea butter I think I have a good idea of this little device and its quality.Pros: High Performance: The centrifuge operates at 7000 RPM, providing quick and efficient separation of samples. Compact Design: The compact and lightweight design makes it easy to fit on any benchtop without taking up too much space. It’s also portable, which is good and bad I suppose. Very good portability but also very small sample sizes. Difficult to make any real quantity of pea butter with this little guy. Quiet Operation: One of the standout features is the low noise level. They call out the noise level on the page, but as this is the only centrifuge I've ever used. I'm just going to have to trust them that it is quieter than others. User-Friendly: The digital display and simple interface make it easy to set and monitor the speed and time. It’s very user-friendly, even for those new to using centrifuges (IE: me) Stable and Safe: The unit is very stable during operation, with no excessive vibrations. It also has safety features like an automatic stop when the lid is opened, which is reassuring when things are spinning at high speeds.Cons: Capacity Limit: Also mentioned above, but the small size means it has a limited capacity. For larger sample sizes, you might need a larger centrifuge. However, for small-scale "experiments", it’s perfect. Plastic Components: Some parts of the centrifuge are made of plastic, which might affect durability in the long term. However, it’s held up well so far with my random use.Overall, the ONiLAB Scientific Mini Centrifuge has been a strange purchase. Its high performance, quiet operation, and user-friendly design make it an excellent choice for any lab. But I do not have a lab, and really have no use for this machine. So do you work in a lab and need a small portable centrifuge? Or do you just think it's neat and want one so you can say you have one? Do you want to try pea butter? If you answered yes to any of those questions. Go ahead and add this to your cart.

The box arrived just in time for our weekend science project extravaganza! Inside, nestled amongst packing peanuts, sat a gleaming mini centrifuge – a fancy way of saying a tiny spinning machine. My kids, ever the curious explorers, were bouncing with questions. "What does it do, Dad?" they asked in unison."Well," I said, grinning, "today we're going to use it to unlock the secret of creamy milk!"Their eyes widened. Milk? Secret? They were hooked.Following the simple instructions, we carefully poured whole milk into the small tubes. Then, with a whir that surprised them both (it's surprisingly quiet!), the centrifuge began its work. For a few minutes, we watched, mesmerized, as the milk swirled within the tubes.Finally, with a satisfied sigh, I switched it off. We peered into the tubes, a little unsure of what to expect. But it was clear! The milk had separated. A thin layer of yellowish fat sat proudly at the top, while the rest of the tube held a slightly clearer liquid."Wow!" exclaimed *****, the eldest. "It's like magic!""Not quite," I chuckled. "It's science!" I explained how the centrifuge used centrifugal force, like a super-powered spinning top, to separate the lighter fat from the denser milk components."So, that's how they make skimmed milk?" asked my youngest, ever the pragmatist.Exactly! We carefully siphoned off the creamy top layer – the cream – and tasted it. Rich and delicious!Now came the fun part. We whisked the leftover skimmed milk with a little sugar and vanilla extract. But, full disclosure, we did add a generous dollop of store-bought whipped cream to bulk it up. (The mini centrifuge tubes are great, but they don't hold a lot!)The final verdict? A resounding success! The kids devoured their homemade treats, thrilled with the science lesson disguised as a delicious snack.The best part? This little centrifuge is practically silent and stays put, as long as the tubes are balanced. (We did have a mini "centrifuge dance" on the counter when we first tried it – a hilarious lesson on proper tube loading!)Overall, this mini centrifuge is a fantastic tool for sparking the kids' curiosity about science. It's a great way to show them how everyday things work, and maybe even inspire a future scientist (or at least a whiz in the kitchen!). Plus, who can resist a delicious reward at the end of a successful experiment?

I like this nifty little centrifuge. It comes with a circular holder, a rectangular holder, 8 adapters for 0.2ml PCR tubes, and 8 adapters for larger tubes. It is as simple as it gets: you flip the on/off switch to turn it on and off. As far as I can tell, it is fixed-rate. The holders swap easily: just pinch two tabs and the old one releases. I tested the latch and there is an auto-shutoff when opened during operation (or precisely, auto-spindown, since it remains on). The unit isn't particularly quiet, but that's to be expected. It's not expensive, it's small, and it works. However, there are other units which have a lot more features and are only a bit more expensive --- so I can't say that it's a great value for the money relative to other units (though I personally think that it's not a bad deal and the other units are underpriced for what you get).

This centrifuge is great for beginners! It is definitely not toy quality but I'm sure there are more professional ones out there as well.I got this to use for our homeschool classroom to add to our science curriculum. We haven't tried a lot of things, but we turned it on and spun some milk to see if it works. It was fun to see the milk separate and the noise wasn't terrible.It did exactly what it says it will do and seems to be very stable and durable. It is a great price and sparks excitement for science. It would make a great addition to any science class!
