UR FACILITY: WHERE PEPTIDES COME TO LIFE

Walk through our facility with us.

The Synthesis Lab

This is where it all begins. Our solid-phase peptide synthesizers run 24-hour cycles, building amino acid chains one residue at a time. Depending on sequence length, a single batch takes 12–48 hours to synthesize.

[Image: Peptide synthesizers in operation]

What you’re seeing: Automated synthesizers with reaction vessels, reagent lines, and control systems. Each machine can produce multiple sequences simultaneously.

The Purification Suite

Raw synthesis produces crude peptide—a mixture of target sequence and various impurities. That’s where preparative HPLC comes in.

Our preparative HPLC systems separate target peptides from:

• Truncation sequences (incomplete synthesis)

• Deletion sequences (missing amino acids)

• Oxidation products

• Residual solvents

The result? Peptide purity of 99% or higher.

The Analytical Lab

Every batch gets tested before it ships. Our analytical lab houses:

Analytical HPLC: Quantifies purity with precision. You get the chromatogram, not just a number.

Mass Spectrometer: Confirms molecular weight, verifying the sequence is correct.

Karl Fischer Titrator: Measures moisture content—critical for stability.

The Lyophilization Area

Purified peptide is still in solution. Lyophilization (freeze-drying) removes water while preserving structure.

The result? Stable, long-shelf-life powder in sterile vials, ready for research.

The Packaging Station

Finished vials are:

• Labeled with product name and batch number

• Vacuum-sealed with desiccant

• Packed for international shipping

WHY USA RESELLERS CHOOSE US

1. We’re the Actual Manufacturer

Not a trading company. Not a broker. We own and operate our synthesis facility. When you order from Pinecrest, you’re buying from the source.

2. Transparent Operations

Video tours. Facility visits. Real-time calls. We don’t hide behind email-only communication. Ask to see our lab. We’ll show you.

3. Verifiable Quality

Every batch comes with HPLC chromatograms, mass spectrometry data, and Certificate of Analysis. Not generic templates—real data from your specific lot.

4. Small Wholesale Specialists

Most Chinese manufacturers ignore orders under 1,000 vials. We built our business around USA small businesses. Start with 10 vials. Scale to 10,000. Same attention either way.
