100-Sheet Quadrille Lab Notebook

This spiral-bound notebook contains 100 sheets of quadrille-ruled paper with a left-hand margin. Pages are numbered for easy reference and the cover is made from 30 pt chipboard pressboard. Two carbon sheets are included for duplicate records. The sheet size is 9-1/4 x 11 in.

Students and Professionals Recording Structured Data

The quadrille grid suits laboratory notes, engineering calculations and field sketches that require alignment. Numbered pages support formal documentation and audit trails. Users who need wide-ruled, college-ruled or blank pages for general writing should choose a different format.

Quadrille Rule with Numbered Pages

The defining specification is the quadrille ruling combined with pre-numbered pages. This layout fixes the page structure for quantitative entry and traceability. Buyers who require plain, lined or other specialised rulings will not be served by this ruling style.

Questions about this item

Does the 100-sheet quadrille layout with numbered pages need a specific pen type to prevent bleed-through on the 15 lb paper?

Standard ballpoint or rollerball pens work well; the 15 lb stock handles typical lab notes without significant feathering or show-through.

Can the pressboard cover and 30 pt chipboard backing withstand daily stacking alongside heavier textbooks?

Yes, the rigid pressboard cover and 30 pt chipboard backing resist bending and protect sheets when stored under larger books.

How do I confirm the spiral binding is aligned so all 100 sheets turn flat without snagging?

Open the notebook fully; each sheet should lie flat against the 9-1/4 x 11 in surface and the left-bound spiral should rotate smoothly through every perforation.
