MAKING A STANDARD % GLUCOSE SOLUTION
To make a Glucose 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.
•
To make an X Glucose solution weigh out X grams of high purity Glucose
(CAS #: 50-99-7) directly into the container.
•
Add distilled or deionized water to the container so the total weight
of the solution is 100g.
• Note:
Solutions above 20 % may need to be vigorously stirred or
shaken and heated in a water bath. Remove solution when
glucose has dissolved. Cool completely before use.
