• A cosa serve Heavy Metals Test 5-in-1?

  The 5-in-1 Heavy Metals Test contiene un reagente colorimetrico ideale per quickly e preliminarily confirming the presence of più comune heavy metals. Serve a identificare con certezza cadmium, mercury, lead, copper, e zinc, as well as to rule out other, less predictable, unwanted substances.

  The reagenti can indicate the PRESENCE of these metals, but not the QUANTITY. Mixtures can be reliably detected with reagenti only if one of the substances produces a stronger reazione di colore. To identify all components with maximum precision, a set of different tests is required.

• Cosa contiene il Heavy Metals Test 5-in-1?

  The Heavy Metals Test 5-in-1 include a two-part colorimetric reagente, a micropipette, a reaction tube, e instructions. The kit contiene enough reagente for at least one test. The tightly sealed plastic container protects the reagente from light e moisture, ensuring a shelf life of at least 3 years after purchase.

• What can be tested with Heavy Metals Test 5-in-1?

  Only liquid samples can be tested – when testing solids, mix them with 4 ml of bottled water e filter out the solid particles. You can test herbs, powders, water, e other liquids (including breast milk, saliva, e first morning urine), food, kitchen utensils, e other objects, including toys e paints. If testing food, blend it e extract the juices. When testing fish, heat a raw campione in a microwave for 20 seconds to collect the juices.

  The campione’s pH should be close to 5.0; strongly acidic o alkaline substances cannot be tested. The test works best at 5 PPM o higher of heavy metals, but it may detect as little as 1 PPM o less.

• Come usare Heavy Metals Test 5-in-1?

  PREPARE THE REAGENT

  From the kit di test, take out the small vial with the dry reagente e the larger tube with the liquid reagente. Pour the contents of the small vial into the larger tube to combine both parts of the reagente, close the tube, e shake for 10 seconds.

  ADD THE SAMPLE

  Immediately add the campione to the prepared reagente solution: 4 ml of liquid, o a solution made by mixing a dry campione with 4 ml of bottled water. 4 ml corresponds to one full volume of the included micropipette. The micropipette can be used several times to conveniently transfer the 4 ml. Filter o carefully decant the solution to avoid adding any undissolved particles into the reagente tube. Close the tube e shake for 5 seconds to mix the campione with the reagente solution.

  OBSERVE FOR 60 MINUTES

  Place the small tube upright with the cap facing down, so the rounded end points up, e observe the cambiamento di colore reaction for 60 minutes. Both the initial colors right after adding the campione e the transitional e final colors are important. Take photos during the reaction.

  CONFRONTA I RISULTATI

  Compare with the expected results provided in the instructions. Ignore any color changes after 60 minutes unless otherwise specified. Match the observed cambiamento di colore with the guide. The reagenti can indicate the PRESENCE, but not the QUANTITY. Mixtures can be reliably detected with reagenti only if one of the substances produces a stronger reazione di colore. To identify all components with maximum precision, a set of different tests is required.

  Seal the used materials inside the plastic tube e dispose of them safely.

• Come interpretare i risultati?

  

   

  Expected Results for the Heavy Metals Test 5-in-1:

  • Mercury – yellow-orange → light orange

  • Cadmium – orange → dark orange

  • Lead – rusty red

  • Copper – purple → brown → yellow

  • Zinc – dark green → light brown

  • Negative – dark green → yellow

   

• Come maneggiare reagenti?

  I reagenti contengono sostanze chimiche tossiche e/o corrosive, abbastanza forti da bruciare pelle e vestiti. Keep out of the eyes e mouth. Tieni lontano da bambini e animali. Usa sempre in un’area ben ventilata. Indossa guanti e occhiali protettivi. Never point towards the face etc. Se ne finisce su di te o sui vestiti, lava subito con abbondante acqua e sapone. Smaltisci ogni reagente non utilizzato con acqua corrente, arieggiando. Conserva i reagenti in posizione verticale, lontano dal calore, in un luogo fresco e buio.

  I reagenti si deteriorano nel tempo o per il contatto con l’aria, soprattutto se esposti alla luce solare o non refrigerati. Se non sei sicuro che il reagente funzioni, provalo con un campione già confermato.
