Specific Gravity Analysis - Liquid Fertilizers
Accurate Density Data for Consistent Mixing, Labeling, and Application
Precision Starts with the Right Weight
When it comes to liquid fertilizers, specific gravity(SG) is more than just a number—it’s a critical measurement that affects blending accuracy, label compliance, and nutrient delivery. Our Specific Gravity Test for Liquid Fertilizers provides fast, lab-grade results to ensure your product meets formulation standards and flows exactly as expected.
Why Specific Gravity Matters
- Label Accuracy – Convert weight-based nutrient values to volume-based application rates
- Batch Consistency – Verify density across different production lots
- Mix Compatibility – Ensure proper blending with other liquids or tank mixes
- Shipping & Packaging – Calculate volume-to-weight ratios for totes, jugs, and drums
What’s Included in This Test
- Specific Gravity Measurement – Reported as g/mL or equivalent weight per gallon
- Temperature-Controlled Testing – Performed under standard lab conditions for accuracy
- Optional Blend Verification – For multi-nutrient or customized liquid products
Sample Requirements
- Minimum Sample Size: 12 ounces of liquid fertilizer
- Packaging: Secure, sealed container labeled with product name
