Ease Your Burden in Bioburden Testing
MODERNIZING MICROBIAL QC

What Is Automated Bioburden Testing?

The Growth Direct® System automates this process, detecting microcolonies in as little as 16 hours and delivering final results in ~36 hours. Validated under USP <1223> and Ph. Eur. 5.1.6, it reduces manual steps, ensures data integrity with electronic records, and supports faster, more reliable product release.

WHY IT WORKS

Key Benefits

Automated bioburden testing with Growth Direct® gives teams faster, more reliable results without changing their compendial process. By combining digital imaging, automated incubation, and direct LIMS integration, the system reduces human error, improves data integrity, and accelerates product release decisions.

PERFORMANCE AT A GLANCE

Manual vs. Automated Bioburden Testing

Traditional bioburden methods are slow, labor-intensive, and prone to variability. By automating the same compendial process, Growth Direct® delivers faster, more reliable results — giving teams the data they need sooner to make confident release decisions.

AUTOMATION WITHOUT DISRUPTION

Seamless Integration with Your Existing Bioburden Workflow

Follows Your Compendial Process.
Growth Direct® uses the same USP <61> membrane filtration and plating methods you already rely on. From sample preparation to incubation and CFU reporting, the system automates each step while preserving your validated approach.
Fits Within Your QC Lab.
Growth Direct® cassettes are filled with compendial media (TSA, SDA) and consumables are designed to slot into your existing processes with minimal disruption, reducing the effort and risk of revalidation.

ONE SYSTEM FOR ALL BIOBURDEN SAMPLES

Media & Cassette Technology

Growth Direct® is designed to support bioburden testing across in-process materials, bulk drug substances, and finished products in GMP-regulated environments.

  • Standard Pharmacopeial Media – TSA for general bioburden testing and SDA for yeast and mold detection. No specialized or proprietary media required.

  • Optimized Cassette Design – Each cassette includes a black 0.45 µm membrane to enhance autofluorescence signal-to-noise, improving sensitivity for early microcolony detection.

  • Barcode-Enabled Traceability – Built-in labeling ensures automated sample identification, seamless LIMS connectivity, and full audit readiness.

  • GMP-Ready Manufacturing – Consumables are filled and irradiated under controlled cleanroom conditions, providing consistent quality and long shelf life.

Frequently Asked Questions

Get answers to the most common regulatory, validation, and integration questions about Growth Direct®.
How does my facility increase bioburden testing efficiency while reducing human error and improving data integrity?

Automation with Growth Direct® replaces manual colony counting and data transcription with digital imaging and direct LIMS integration. This reduces operator variability, eliminates transcription errors, and creates 21 CFR Part 11–ready electronic records — all while cutting time-to-result by up to 50%. Read more.

Is automated bioburden testing accepted by regulators?
Yes. Growth Direct® aligns with USP <61>, USP <1223>, Ph. Eur. 5.1.6, and the proposed USP <1119>/<1119.1>. As an automated compendial method, it requires only verification and method suitability studies. The system has been validated and implemented in FDA- and EMA-regulated facilities.
What types of samples can be tested?

The Growth Direct® System is suitable for a wide range of pharmaceutical and biologics applications, including in-process materials, bulk drug substances, intermediates, and final product testing. It is validated for use with TSA (general bioburden) and SDA (yeasts and molds) media, supporting routine bioburden testing needs.

In addition to direct inoculation on Growth Direct® cassettes, the system supports samples prepared by both membrane filtration (for aqueous samples such as water, buffers, or bulk liquids) and spread plate methods (for viscous or complex sample matrices).
