Description
The HI96802 Digital Fructose Refractometer converts the refractive index of a food sample to % fructose by weight. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in refractive index with temperature for a percent by weight fructose solution. The HI96802 is ideal for the analysis of fruits, energy drinks, puddings, soy milk, juices, jam, marmalade, honey, soups, jelly, tofu and condiments. The HI96802 is an easy to use tool for measuring sugar in food samples in the field or in the HI96802 lab.
- Designed for food sugar analysis
- Temperature Compensation algorithms based on fructose solution
- 0 to 85% fructose by weight range with an accuracy of ± 0.2%
Making a Standard % Fructose Solution
To make a Fructose Solution, follow the procedure below:
- Place container (such as a glass vial or dropper bottle that has a cover) on an analytical balance.
- Tare the balance.
- Weigh out X grams of high purity fructose (CAS #: 57-48-7) directly into a beaker
- Add distilled or deionized water to the beaker so the total weight of the solution is 100g.
- Note: Solutions above 65% may need to be vigorously stirred or shaken and heated in a water bath to roughly 40°C (104°F). Remove solution when fructose has dissolved and allow to cool before use.
Example to prepare as 25% fructose solution:
| Fructose % (g/100g) | Fructose (g) | Water (g) | Total (g) |
| 25 | 25.000 | 75.000 | 100.000 |
