ONiLAB 280℃ 5 inch LED Digital Hotplate Magnetic Stirrer with Ceramic Coated Stainless Steel Work Plate, 200-1500rpm,110V,Temp Probe Sensor and 9PCS Stirring Bars Included

The lab heater magnetic stirrer is an excellent machine. It is well engineered and the controls are simple, obvious and effective. I had a problem with the unit and I contacted customer service. They had a new unit in the mail by the end of the day! I highly recommend the product.

I am very impressed with my new laboratory hot plate. I am used to paying over twice as much for hotplates. I like the small footprint of this hotplate, it sits well on my bench without taking up too much space. All I had to do was plug it in, add the connector on the back for the PT1000 sensor and put the sensor on my lab stand (it didn’t come with a stand – I wasn’t expecting a stand either at this price, plus, I prefer my personal laboratory stand).Once I had the setup ready, I placed a 1Liter beaker on the clean ceramic surface, placed the magnetic stir bar that came with the hotplate (always add your magnet first!!!), added my test liquid (waterJ) and tested all features.The hotplate comes with an on/off switch. Once you turn on the unit, you may select the desired heating temperature by turning the left knob. Once you are happy with your setting, you push the button and it turns the heating feature on. If you are simply warming up your liquid, you may not need or want to use the temperature sensor. If your liquid has to be heated at a certain set temperature, make sure your PT1000 sensor is connected at the back of the plate and you’ll see the actual liquid temperature displayed on the unit. I really like the readouts, so I know that I am not overheating the liquid.Once the temperature goes above 50 degrees, and you turn off the device, it displays the HOT warning sign, which is a must have to prevent accidental touching while the surface is still hot. This is one of the key reasons why I like the digital hotplate over the old style analog hotplate.I prefer to use the stirring function differently than how I set my heating temperature. For stirring, I prefer to start with small increments while observing the vortex formation, once I am happy with the consistent stirring and the vortex, I write down my stirring speed so I can use this setting again for future runs. I have learnt the hard way in the past that if you spin up any stir plate too quickly, it decouples the magnet.Sorry for the long review, but I am just too happy and excited about this cute little hotplate that I plan to use every day and I want to pass on my strong thumbs up for the device for your everyday, low viscosity fluid heating and mixing. For the price, it’s a great deal—watch out Corning, you have a true competitor at half the cost!

Nice little hotplate. It heats up super quick and comes with a temperature probe. The manual that comes with it is on a CD and I preferred a pdf version. I contacted seller for a compatible stand and operator manual. They responded within a couple days(right after new years) and fulfilled my needs there. Decent price for the hotplate, especially with the temp probe that ties into the unit.1/17/2020 update:Recieved a package from LabGenome the other day. I assumed it was the probe stand I was looking for earlier. However upon opening I discovered much more than just the burette stand. Also included was 3-6packs of different magnetic stirrers, an extra temp probe and a really cool electric pipette filler. Labgenome went above and beyond the mark for this one. When I figure out how to review them I will give them a good rating as well! Thanks Labgenome!!! You got me as a customer 👍

I bought this device a while ago then start to use it and after two days the hot plate was dead, I called to customer Service and nice lady gave me email address . They answer me next day and start to give me a tips how to solve this problem, it was easy nothing complicated and after nothing help they send me replacement heat plate and… you ready? THE NEW MACHINE! so after I will fix my previous device I will have TWO machine! Even I had problem with first device I give 5 stars for customer Service and for how they took care of customers. Thank you guys!

I bought it because lab equipent are supposed to be highly accurate.If I set it to 85 the thermostat will level off at about 79 but I cabn assure you it has heated to way hotter than 79.So perhaps the reading is off on the display.It's weird and frankly dangerous that it is hotter than it reads.

Purchased this product to keep formula at a range of 98 to 102 degrees Fahrenheit. (Although the warmer registers in Celsius it is easy to convert the math). As seen in the photo, I found that it works best keeping the temperature probe in a water bath in a glass bowl, and a Pyrex glass measuring cup holding the formula inside the bath to keep a steady temperature. I would also recommend warming the water bath on the lab warmer first, then heat the formula in the microwave to the desired temperature before placing inside the bath. It worked so well I purchased a second one! Unfortunately one of the warmers stopped working but the seller was very responsive, worked hard to fix the problem and quick to replace it! They were very generous and I'm extremely satisfied! Highly recommend!

The build quality and the inclusion of a PT1000 temp probe is a big positive at this price point. Temperature control using the external RTD is fine and holds within stated tolerances. The RTD itself is accurate and arrives packaged well. For delicate heating and temperature control tasks this is a good value for the price.
