Product Description
Calibrating a refractometer with a solid test block requires a good optical bond between the block and the prism. This bromonaphthalene contact liquid fills the tiny gap between surfaces, eliminating air and giving a sharp borderline so your calibration check is accurate. It is an essential consumable for labs that verify instruments regularly.
This listing is for catalog number 45000-OS001: Refractometer Contact Solution (Bromonaphthalene), NIST. Bromonaphthalene is a high refractive index liquid widely used as an optical contact medium for refractometer test pieces and reference prisms. Only a small drop is needed for each check, so a single bottle lasts through many calibrations. The solution is listed as NIST traceable, supporting documented quality procedures. Order it from LIGHT LABS and keep your bench running smoothly.
Key Features
- High refractive index – Forms a clean optical contact between test block and prism.
- NIST traceable – Supports documented calibration and QC records.
- Sharp readings – Removes air gaps that blur the light-dark boundary.
- Economical – A single drop per calibration stretches each bottle.
