National Laboratory Notebook, 4 x 4 Quad Ruling, 11" x 9.25", 100 Numbered Sets (43649)

This lab notebook worked well for me. The pages are well organized, durable, and easy to write on without ink bleeding through. It held up throughout the semester and met all my lab requirements. If you need a reliable, standard lab notebook for school or research, this one gets the job done.

Arrived quickly, good condition over-all. Perfect for studying. The cover is plain but these are just research notebooks, you can bend the front flap comfortably and it is flexible. It's thicker and heavier than it looks but it has withstood some rough use already.

For $21 the is the Best Carbonless Copy/duplicate Lab Notebook on the market.Pros:-Water resistance fabric on binding, protects from water and chemical spills and manhandling.-Thick water resistance cardboard shell, with sticker on front to notate info.-First Page is a table of contents, again with fabric binding and a hard cardstock/cardboard page.-Perforated pages, which tear out easily. Yet, strong enough they haven't torn out on accident while writing in lab notebook.-Only Grid and page numbers on carbonless copy pages!-No additional tables, conversions so it can be used for my pre-lab quizzes!Cons:-The page divider in back was not perforated and difficult to ripe out for useage.(Infact, I didn't remove it for fear of ripping. Also the cardboard in the back of the notebook added to it's structural integrity. I used a laminated periodic table on cardboard that I used instead-no bleed through to other pages.)-No periodic table or extras in this lab notebook. I prefer it this way. Other might wish for more!

tried this book bc of carbon copy tech and it's fantastic.from my lens, this book is primarily designed for right hand side note taking. detached pages likely for assistant instructions who come back and mark when done.if you regularly use same notebook without carbon, this one isn't entirely conducive for writing on the back of carbon copy. you can but with a soft tip pensmall point, not a deal breaker, you need a heavier piece of paper/manila folder to ensure notes don't press through to other pages. the book does not have a flip page for this.i wholeheartedly recommend but give four stars only because i often work in my lap and the book seems to work best on a bench

Not what I expected. I've been purchasing these since 2006, and never had 1 like this. Maybe I just made a mistake, I won't rule it out. But the last few I had I bought from Amazon and they weren't like this, single pages with a backing similar to a financial ledger. It's always been both sides, front and back, numbered and bound. AKA a legal document if you sign and date your entries as an engineer. I didn't give less stars because 1 new thing that is an improvement is a beginning section for listing what's on what pages.

This is a really expensive notebook.And it is worth every penny. Have been using that’s for about 20 years amd the first one still holding up great.Pro tipI used my calendar as a reference to quickly find relevant notesFrom my notebooks during long duration projects (years)

Thick and sturdy research notebooks

Works great for chem labs, has lasted me through 4 different labs and I still have plenty of pages left. It is kind of bulky but it does the job

better than I expected

Exactly what we required
