LABORATORY NOTEBOOK 200 5mm serially numbered (hardcover edition) pages, black, A4, grid,

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Size: A4 Thickness: approx. 15mm Weight: approx. 1000g Total number of pages: 216 (inside cover, management page, guide page, table of contents 10 pages, record pages 200 pages), with front and back notes Binding: Thread binding, hard cover Paper quality: Neutral paper Cover: Matte PP processing With removable memo pads on the front and back. The notebook will not bulge even if you stick paper on it by removing the pads. (Patent No. 3766680) NGB LABORATORY NOTEBOOK has been used by many customers since its release in 1995, and is durable due to its sturdy binding, and the record pages are printed with consecutive numbers to prevent cutting out or tampering. It also has a layout that can be used for a wide range of purposes. [Storage] One of the conditions for a lab notebook is a minimum of 30 years (20 years for patent term + 6 years for litigation period + alpha). The reason that loose-leaf paper is avoided is because the pages are not firmly bound and will fall apart. Once the pages are separated, there is a high possibility that they will lose their function as evidence. For this reason, commercially available notebooks are not stable. [Special layout] For a lab notebook to be completed as evidence, it is essential for a witness to sign and write the date. In addition, when writing notes, in addition to the research content, you must also write the note number, research objectives, project number, title, etc. If you neglect to do so, it will not only affect the admissibility of the notebook as evidence, but it will also cause problems in the future management and operation of the notebook. You can see that commercially available notebooks are insufficient as evidence because their layout is not designed for experimental purposes with the expectation of patenting the invention.
