SAFETY: Some of the exposed wires described in this video are plugged into your home outlet which is 110/120V AC power. The hot plate and heating elements get super hot. This is dangerous. Use the information presented in this video at your own risk. I am not liable for any damage or injuries or monetary losses or distress. See full disclaimer below.
Parts List:
Aluminum blocks and plates

If in SF Bay Area, Alan Steel & Supply Co is fantastic.
Cartridge Heaters
amzn.to/3RaKjVK
PTC heaters
amzn.to/3XRMKz2
PID Controller + Relay + K-type thermocouple
amzn.to/3wwsRBL
Wago (Lever Wire) connector. This off brand works great:
amzn.to/3kMjyuF
Use any cable with a 3-prong power plug
Here's one on Amazon for $9: amzn.to/3RfOmjW
Wire

Use wire rated for at least as many Amps as you expect to draw. 14 gauge is probably good. 16-12 gauge should work depending on your requirements.

*Rated up to 400F. Make sure this works for your application.
I have a home lab I use to make microfluidic devices to grow human tissues with blood vessels in the lab. One step involves heating silicon wafers to precise temperatures using hot plates as part of a process known as photolithography. These hot plates provide accurate, precise, and uniform heating of the wafers. Also great for reflowing PCBs, making lab hot plates or heat blocks.

Subscribe to stay tuned for more great DIY science videos. Will be discussing how to do high resolution photolithography and make microfluidic devices at home among other things.

I like how you started with a demo... good work!
don't forget to read Mike's description for more info.
My left ear appreciated this video. I don't have access to a drill press so will go with the PTC. I also want to be able to use it with stir bar, looks like I still can.
Very informative, thank you! Appreciate this.
By the way, note the difference between ceramic and aluminum top hot plates. On ceramic (poor heat conducting material) top plates, the surface temperature will not be uniform. The center will be close to the set temperature but the edges will be cooler. Also, check the manual here of a ceramic top hot plate (www.google.com/url?sa=t&source=web&rct=j&url=www.corning.com/catalog/cls/documents/equipment-manuals/CLS-EQ-091DOC.pdf&ved=2ahUKEwiKqubHj-X7AhXeHEQIHRmrDdgQFnoECBEQAQ&usg=AOvVaw1c3iu41GHsDfAtLlKhffd1) on page 8 which says that the set temp can differ from actual temperature. Ceramic hot plates are ideal for heating beakers with liquids (and you would have a thermometer or probe in the liquid to monitor the temperature). The ceramic material is corrosion-resistant and can also withstand higher temperatures than aluminum. For uniform and more accurate surface temperatures though, go with an aluminum top hot plate. Ceramic-coated aluminum top hot plates are a thing if you need the best of both worlds and will cost several hundred dollars, though they can't get as hot as ceramic-only hot plates. But most people probably don't need ridiculously hot temperatures.
Thanks, just the words im looking for
Important video to watch to make sure you're getting accurate temperatures: th-cam.com/video/Ron89whg_M8/w-d-xo.html
yes, i went through your other videos, then found that video helpful, to complete this project. I am going to try your design for the bigger one. Very cool. And i hope the best in your biology project involving the micro fluid device to grow human tissues with blood vessels.
Hi there. We found you doing electroncis so much fun, and were wondering if any prototype services may help? Would love to supply and reach any YT collab together! Is there anyway we could get you connected? (PCBWay luz)
