The Complete Handbook of Laboratory Hot Plates

I run a small environmental testing lab and have bought hot plates from three different brands over the years based on sales pitches. This book finally explains what the specs actually do. The chapter on temperature control and how thermocouple placement matters saved me from buying a unit that would have been wrong for my digestion work.

Good, thorough reference. The sections on maintenance and calibration are clearly written by someone who has actually held a screwdriver. I wish the brand comparison chapter had more pricing detail, but I understand that goes stale. I have already used the troubleshooting flowchart for a stirrer that was dropping out at speed.

Solid content, but the first chapter is denser than it needs to be for someone who just wants to pick a replacement unit. The explanation of PID loops and thermal mass is correct and useful, though. I gave it three stars because it is a reference, not a page-turner, and the chapter order makes you work for the practical selection advice.

Finally, a book that takes hot plates seriously. As a faculty member who trains undergrads, I especially appreciated the installation chapter - it explicitly walks through grounding checks and thermal shock risks that our own safety manual glosses over. I have already assigned the first two chapters as pre-lab reading for my analytical chemistry class.

Bought this for my home chemistry setup and it paid for itself in the maintenance chapter alone. My used hot plate had a noisy relay and I fixed it in an afternoon thanks to the diagnostics section. The business chapter is a bonus - I am thinking about repairing units for a hobby income.

It is a decent handbook, but more geared toward institutional buyers than serious hobbyists. I wanted more on small inexpensive units and repurposing parts. The troubleshooting section is good, but it assumes you already have a high-end unit with digital control. The chapter on brands felt like it was leaning on names I have never seen in retail.

As someone who buys lab equipment for a food testing facility, I found the chapter on selection to be the most useful part - it gives a concrete process instead of generic advice. I still think a hot plate is a simple device and the book over-explains the physics at times, but the practical checklists are worth the price. The maintenance schedule is now posted in our lab.
