OUT OF STOCK Gold Test Needles


To be used in conjunction with gold testing acids and test stone to evaluate the karat content of gold. Set of 5 needles includes 8, 10, 12, 14 and 18 karat gold.

Gold test needles act as benchmarks or gauges to compare unknown gold objects for color reference when using acid or premixed gold test solutions to determine their gold content. Needles are also a necessity for checking premixed test solutions for accuracy, and to make sure they have not deteriorated over time. If the test needles are not the correct alloys they will not give you the correct reading. It is important to recognize that test needles are the heart of any test system that uses acid solutions to test for gold content.
