*Capsule sizes are based on loose bulk density. If tapping/compressing, you may be able to go down one size.
 

1. Loose vs. Tapped Density

  • Loose Density (pL): Calculated by pouring powder into a cylinder without agitation. This is used for standard gravity-fed capsule filling.
  • Tapped Density (ρT): Calculated after tapping the cylinder 100+ times to settle the particles. This is used when using a manual tamper to pack more material into a smaller capsule.

2. Flowability (The Hausner Ratio)A true researcher calculates the Hausner Ratio (H = ρT / ρL).

  • 1.00 – 1.11: Excellent flow (easy to fill).
  • 1.26 – 1.34: Passable flow.
  • >1.46: Very poor flow (requires fillers/excipients).

3. Calibration Hardware List

  1. Digital Milligram Research Scale: Provides the essential Mass variable down to 0.001g precision.
  2. High-Resolution Glass Graduated Cylinder: Used to capture the exact Volume occupied by the powder.
  3. Static-Neutral Micro-Scoops: Prevents "static cling" where powder sticks to the sides, which can artificially inflate the volume reading.

Research Protocol: Volumetric Density Calibration

1. Purpose To establish the Bulk Density (ρ) of a specific batch of nootropic powder. This allows for accurate conversion between mass and volume for precise encapsulation or liquid suspension.

2. Required Instrumentation:

  • Digital Milligram Scale: Must have a minimum resolution of 0.001g.
  • Glass Graduated Cylinder: Borosilicate glass is preferred to reduce static.
  • Anti-Static Micro-Scoops: To prevent powder loss during transfer.

3. Procedure A: Loose Bulk Density (ρL)

  1. Tare the Cylinder: Place a clean, dry 10mL graduated cylinder on the scale and press "Tare" to zero the weight.
  2. Add Powder: Slowly add the nootropic powder until it reaches exactly the 10mL mark.
    • Crucial: Do not tap, shake, or compress the cylinder.
  3. Record Mass: Note the weight displayed on the scale in grams (g).
  4. Calculate: Enter this weight into the Universal Density Engine on our website to find your g/mL value.

4. Procedure B: Tapped Density (ρT)

  1. Settle the Powder: Take the same 10mL cylinder from Procedure A.
  2. Agitation: Tap the base of the cylinder firmly on a padded surface (like a mousepad) 100 times.
  3. Observe Volume: Note the new, lower volume level (e.g., it may have dropped to 8.5mL).
  4. Re-Calculate: This "Tapped Density" is what you should use if you plan to manually compress powder into capsules using a tamper.
