Dilution Instructions to dilute 4000 NTU foramzin to 20 NTU
Antwort
To perform the dilution, you will require the following:

Consumable items
  • PN: #246142 4000 NTU Formazin Solution (100ml)
  • PN: #27248 Deionised Water (500ml) x 2
  • PN: #1406053 Volumetric Flask (1000ml)
  • PN: #BBP065 Pipette (1.0ml – 5.0ml)
  • PN: #BBP068 Disposable Pipette Tips (75pk)
Step 1: Create the 20 NTU dilution

Begin the 20 NTU dilution by following the below steps in the order they are written:
  1. Set Pipette to capture a 5.0ml solution.
  2. Use Pipette to draw 5.0ml of 4000NTU Formazin Solution (#246142).
  3. Add 5.0ml of 4000 NTU Formazin Solution (#246142) to the Volumetric Flask (#1406053)
  4. Fill remainder of Volumetric Flask (#1406053) with DI Water (#27248) to 1 Litre mark.
  5. Invert gently to mix (do not shake).
  6. You have created a 20NTU Formazin dilution.
Step 2: Use 20 NTU Formazon Solution
This 20 NTU solution can now be used to calibrate the 17200E, Ultraturb, or any other turbidimeter requiring a 20 NTU standard.
