See "Restrictions" for more information.  Five bottle tester, tests for all carats of gold and also silver (identical to the QUICKTEST-3), plus a fourth bottle for white metals (identical to the 4th bottle  the 4-bottle Troytest) PLUS a fifth bottle for testing low carat gold (e.g. 5ct to 8ct) and 9ct gold containing a lot of zinc.

To read an article about testing precious metals   DETAIL Troytest is the 'original' precious metal tester, invented in 1949.  Quicktest bought Troytest in 2008. Each bottle contains enough fluid for 150 tests (the 'use-by' date is printed on each label). Each bottle is transparent so that you can see how much fluid remains. Accessories: steel needle file, powerful neodymium magnet, instructions booklet, chart (indicator disc), test-papers, polishing paper, copper sample. They all fit inside a secure (lockable) wooden box with the bottles. The first bottle tells you if the metal is 9ct or not gold ('base' metal) or better than 9ct. It has a shelf life of 1 to 2 years (the date is printed on the bottle).  The second bottle tells you if the metal is 14ct, 18ct, 22ct or 24ct (and it's accurate enough to gauge 'in between' these readings). It has a shelf life of up to 2 years (the date is printed on the bottle). The third bottle tests for silver (Sterling, 925 grade or 'continental' .800). It has a shelf life of up to 2 years (the date is printed on the bottle). The fourth bottle (known as the 'green' bottle or the 'platinum' bottle) is for white metals so that you can distinguish white gold, platinum, Palladium and steel. It has a shelf life of about 1 year (the date is printed on the bottle). The fifth bottle (known as the 'clear' bottle or 'low carat' bottle) tests for 5ct to 8ct, and also a rare alloy of 9ct that happens to contain a lot of zinc. It has a shelf life of up to1 year (the date is printed on the bottle).  The reactions are very clear, you don't have to distinguish between green, grey and brown.  VIDEOS Preparation, , click here to play the video - good to see this if you have never used testing acids before.
