    • Very useful and good customer service
Style: 280 with stand
I've been using this for about 6 months, making cosmetic formulas. I bought 2 units. I tested them with external thermometers and found one of them wasn't heating properly. The company promptly replaced it. I find that the units will heat to the desired temperature, but the speed at which this happens depends on the content of the solution. Water doesn't heat as fast as oil, for instance. If I want to heat quickly I can turn the temperature to the highest setting and watch the unit to see when the correct temperature is reached. Or I can set to the desired temperature and wait longer. I also discovered that I needed to push really hard to properly connect the thermometer cable to the unit. This company does make a higher-end more sensitive until, which I have just purchased, as well. Update: I also purchased the ONiLAB 340C Magnetic Hotplate Stirrer with Aluminum Work Plate. I prefer it because it allow me more control over the heating function. "A" allow quicker heating with less accuracy, which is fine if I can monitor the solution. If I don't want to have to monitor the heating, the "C" option heats slowly but accurately. The "B" option is in the middle. I use both of these hotplates, but I use the 340C version most. ... show more

    • Great accurate and long lasting
Style: 280 with bars set
I purchased this over a year ago, I’ve had some bad experiences with other brands that were much more expensive. This has been a workhorse. It’s a great tool for a home brewer, you can get your starters going in no time I’ve had to leave it running for days at a time when brewing for comps and it just keeps going. Well worth the expense. ... show more

    • Not that great
Style: 280
If the ambient room temperature is less than about 65F, the internal temperature sensor fails and the unit shows ERROR. The hot plate will not heat. The only solution is to either plug in the external temperature sensor until the hotplate warms up the internal sensor or move the machine to a warmer room. This is very inconvenient. Upon initial start of the magnetic stirrer, it jumps to a very high speed, then settles to the set speed. This can be a problem in some cases. It seems like poor design. ... show more

    • Perfect little laboratory hot plate - A must have for all biology laboratories
Style: 280
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! ... show more

    • A nice machine, took some getting used to
Style: 280
I have modest heating needs, rarely anything over 100C, and this hot plate accomplishes that easily. I more often need a stirrer, working with volumes from 100ml up to 3 liters. So far, this stirrer has had no trouble with anything I have asked of it. It has a good, strong magnetic grip on the stir bar and does not lose the bar even when getting hit with solids, as when sterilizing explants, for example. My previous stirrer was pretty wimpy and the stir rod would frequently be dislodged, which is always annoying. I am accustomed to analog stirrers, so I had to change my expectations with this digital device. Turning up the speed does not result in an immediate change. It slowly ramps up the speed to match the setting. If you are used to cranking an analog knob back and forth, it is a little disconcerting when nothing changes but the number on the display. On the other hand, it is nice to be able to achieve exactly the same speed with each batch. I did have a strange experience out of the box, when the stirrer refused to come up to speed. I dialed it up to 1500 and it remained at minimum speed for at least ten minutes, before it started climbing up to full speed. I contacted their customer support and received a quick response but, after that first time, it has always responded normally. ... show more
