Archival-quality paper: 
Permanent records must be both archival, lasting several hundred years or more, and extremely durable to withstand repeated handling.  Our #1 sulfite ledger paper is acid-free and contains a calcium carbonate buffer for maximum resistance to deterioration.  The slightly off-white color was formulated to be easy on the eyes.  The private watermark provides both security and prestige.

Oversized page format:
Pages have 4 to the inch grid with faint vertical lines. 11" x 8-1/2" paper can be affixed to the pages without covering the header or footer.

Round-back binding:
Expandable and durable, your lab book will allow for pasted-in printouts and lay flat for microfilming. The unique wide joint allows the book to grow to 2-3 times the thickness - as the picture above demonstrates.

Section-sewn:
Your laboratory notebook's integrity will be maintained -- in the section-sewn notebook, no pages can be added or torn from the book without disrupting the binding.  Section sewing also allows for optimal lay-flat.  The thread is 100% cotton and acid free.

Hard, fully wrapped cover:
Each notebook cover is constructed of heavy duty 100 gauge boards fully wrapped in your choice of black or blue imitation leather.

Embossing:
If you like, the words "LABORATORY NOTEBOOK" or "ENGINEERING NOTEBOOK" may be embossed in gold foil on the front cover with no increase in price or delivery time.
Eureka can also stamp company name, logo, department, or anything else required and there is no minimum quantity.  Please email us at sales@eurekalabbook.com and attach an example of what you’d like custom stamped.

Numbering:
Our notebooks can be sequentially numbered starting with the number of your choice (provided it is no more than 6 digits). You may select numbering on the cover or spine for $1 more per book, or choose numbering on both cover and spine for $2 more per book. Allow an extra week for delivery.
