Bellingham + Stanley Refractometer Service Calibration Pack: 20 x 5ml (UKAS/NIST).  Sealed Glass bottles with screw cap.

This pack contains 18 bottles of calibration fluids covering the typical working range of a refractometer.  For additional coverage above 1.53 RI (95 Brix) we recommend the additional purchase of our BSDD Calibration Oil that has an refractive index value of 1.56 RI.

Pack contains:

  1. Calibration oils are batch dependent.  Values may vary slightly from those shown.  Refer to certificate supplied.
  2. See table at the bottom of this page for uncertainty statements or refer to our literature for more detail.  

This pack is ideal for verifying the performance across the whole range of a refractometer as part of an operational performance test during an initial installation of a high performance refractometer (IQ/OQ/PQ) such as an Abbe or RFM refractometer or as part of an ongoing annual performance audit (PQ) by a user or Calibration Certification service provider.

Supplied with 20 pipettes, SDS information and UKAS Calibration Certificate (ISO 17025) for each value.

Supplying refractometer calibration materials in small volume bottles protects against adulteration between use compared to, say, a single 100ml bottle.

  • Lowest cost option
  • Long life
