Lab Testing & COA Guide
Whole Melt Lab Test & Certificates of Analysis
We believe in complete transparency. Every product undergoes comprehensive third party testing to verify potency, purity, and safety. This page explains our testing protocols, how to access and interpret lab results, and why rigorous testing matters for premium solventless extracts
Why Lab Testing Matters for Solventless Extracts
While solventless extracts like full melt hash and live rosin don’t involve chemical solvents, lab testing remains crucial for several reasons:
Potency Verification
Lab tests confirm the exact cannabinoid content of each product, including THC, CBD, and minor cannabinoids that contribute to the entourage effect.
Terpene Analysis
Our full melt testing includes detailed terpene profiles, which are responsible for flavor, aroma, and many therapeutic effects.
Contaminant Screening
Even solventless products require testing for:
Pesticides
Heavy metals
Microbial contaminants
Mycotoxins
Batch Consistency
The whole melt lab test ensures that every batch meets our strict quality standards for potency and purity.

Understanding Your Solventless Vape COA
Hash rosin and other solventless vape COA test results contain detailed information that may seem technical at first glance. Here’s how to interpret the key sections:
Cannabinoid Profile
Section | What It Means | What to Look For |
---|---|---|
Total THC | The sum of THCA and THC | Typically 70-85% for premium extracts |
THCA | The acidic form that converts to THC when heated | Usually the highest percentage |
Delta-9 THC | Active THC already present | Lower percentage than THCA |
Minor Cannabinoids | CBD, CBG, CBN, etc. | Indicates full-spectrum quality |
Total Cannabinoids | Sum of all cannabinoids | Higher numbers indicate potency |
Terpene Analysis
Common Terpenes | Aroma/Flavor | Potential Effects |
---|---|---|
Myrcene | Earthy, musky | Relaxing, sedative |
Limonene | Citrus | Uplifting, mood-enhancing |
Caryophyllene | Peppery, spicy | Anti-inflammatory |
Pinene | Pine, woody | Alertness, memory |
Linalool | Floral, lavender | Calming, anxiety-reducing |
Contaminant Testing
Test Type | Pass Threshold | What It Means |
---|---|---|
Pesticides | Non-detect or below action limits | Free from harmful agricultural chemicals |
Heavy Metals | Below action limits | Safe from lead, arsenic, mercury, cadmium |
Microbials | Below action limits | Free from harmful bacteria and mold |
Mycotoxins | Non detect | Free from fungal toxins |
Third Party Tested Vape: Why It Matters
Independent Verification
All Whole Melt products are tested by ISO-accredited, independent laboratories with no financial interest in our products. This ensures unbiased, accurate results you can trust.
Regulatory Compliance
Our third party testing meets or exceeds all state requirements for cannabis product safety and labeling.
Consumer Safety
Independent testing protects consumers by verifying that products are free from harmful contaminants and contain the advertised potency.
Quality Assurance
Regular testing throughout our production process helps maintain consistent quality from batch to batch.
Full Melt Testing: Special Considerations
Full melt hash and hash rosin require specialized testing protocols due to their unique properties:
Solventless Verification
While chemical solvent testing is still performed, the “non-detect” results confirm our solventless extraction methods.
Melt Quality Assessment
Full melt hash undergoes additional testing to verify its melt quality, which indicates purity and trichome preservation.
Water Activity Testing
This specialized test measures available water content to ensure product stability and prevent microbial growth.
Terpene Preservation Verification
Comprehensive terpene and full melt testing confirms that our extraction methods preserve the plant’s original terpene profile.
Hash Rosin COA Explained
Hash rosin Certificates of Analysis contain specific information relevant to this premium extract type:
Rosin Specific Metrics
Metric | What It Measures | Why It Matters |
---|---|---|
Lipid Content | Fats and waxes | Lower is better for purity |
Terpene % | Total terpene content | Higher indicates better flavor |
Residual Moisture | Water content | Should be minimal |
Consistency | Physical properties | Indicates production quality |
Interpreting Hash Rosin Results
Premium hash rosin typically shows:
70-85% total cannabinoids
4-15% terpenes
Non-detect for all contaminants
Minimal lipid content

Frequently Asked Questions
How often are Whole Melt products tested?
Every production batch undergoes complete testing before release to the market. We maintain a regular testing schedule to ensure consistent quality and safety.
What labs do you use for testing?
We partner with ISO 17025-accredited laboratories that specialize in cannabis testing.
Why do THC percentages sometimes vary between batches?
Cannabis is a natural product, and cannabinoid levels can vary based on the specific plants used in each batch. We maintain strict quality standards, but small variations are normal and expected.
How long are lab results valid?
Lab results represent the product at the time of testing. While cannabinoids remain stable for extended periods when properly stored, terpenes may gradually diminish over time.
