These books are pretty standard for lab researchers or for students. I used them for my General and Organic Chemistry lab courses.

The Good:
-They are durable. The spiral binding isn't flimsy, and it won't fall apart.
-The duplicates are not carbon based.
-The sheets are quadrille ruled.
-If you spill chemicals on your notebook (like I did every day), as another reviewer said, the paper absorbs the chemicals really quickly. But the copy isn't really affected.
-Comes with a handy periodic table and reference table on the divider.
-The duplicates are fairly clear and legible

The Not So Good:
-Be careful what you rest on the notebook because if it's pointy it will leave stray marks on your copy.

Miscellaneous Remarks:
-I can't say this enough, but MAKE SURE YOU PUT THE DIVIDER BEHIND YOUR PAGE and the duplicate. If you don't do that, whatever you write will be imprinted onto the following 1 or 2 sheets (3 if you push hard when you write).
-The copy may look really faint at first, but give it some time. After a few minutes whatever you wrote or drew will become darker and easier to see.

These books are expensive, yes, but they are very useful. I still have mine and look back for reference.

Thanks for reading my review!

This lab notebook is sold at the bookstore of my college for $24 dollars. It is much cheaper here on amazon, plus, it is a high quality lab notebook. The pages don't feel cheap and the spiral binding makes it very sturdy. This is my favorite lab notebook.

This is such a useful, and more importantly, durable lab notebook - the binding of my old one has stayed on for 5+ years and the new one is going strong! Also, the copy pages are just as legible as the originals, and the quadrille-ruled pages help you to copy charts and organize data much better than plain notebook paper.

I was required to use these in my general chemistry courses and now that I'm doing my own research, I knew this would be perfect.

PROS:
Pages are numbered.
Duplicates are made, but if you don't need duplicates you can have a 100 page notebook (numbering will be a bit strange.
Pages are like graph paper instead of regular notebook paper.


CON:
If you spill chemicals on the notebook, the paper will absorb them and then you'll be stuck exposing yourself to those chemicals for the rest of the semester. This is probably true for notebooks, to a greater or lesser extent. :)

I needed this product for a class. I bought the item on Friday and I had it by Monday. Definitely was impressed!
