Stream Sampling Kit (SSK)

About the Product:

The Stream Sampling Kit (SSK) is a patented sampling interface (US Patent 10,520,400) designed to ensure blend content uniformity by enabling real-time quality monitoring and control during powder manufacturing.

Developed and supported by Rodolfo J. Romañach, Ph.D. and Rafael Méndez, Ph.D. from the University of Puerto Rico – Mayagüez Campus, licensed by the Puerto Rico Science, Technology and Research Trust (PRSTRT), and exclusively manufactured by CIS International with the direct support of Dr. Carlos Conde, the SSK is backed by multiple peer-reviewed publications (2020–2024, International Journal of Pharmaceutics).

Traditional sampling methods rely on laboratory testing that is often slow, complex, and prone to biases due to particle behavior. In contrast, the SSK functions as a real-time sampling interface, integrating directly into the process stream and working seamlessly with PAT tools such as NIR and Raman analyzers.

How it Works:

  • Powder flows from a hopper or a continuous mixer to the Stream Sampling Kit
  • Powder is confined within paddles (designed to eliminate the wave pattern)
  • NIR, Raman spectra, or other PAT tools monitor quality in real-time
  • Powder leaves the system, avoiding recirculation (different from what occurs in most feed frames)

How it Works:

  • Powder flows from a hopper or a continuous mixer to the Stream Sampling Kit
  • Powder is confined within paddles (designed to eliminate the wave pattern)
  • NIR, Raman spectra, or other PAT tools monitor quality in real-time
  • Powder leaves the system, avoiding recirculation (different from what occurs in most feed frames)

The system ensures:

  • Gentle powder dynamics for minimum attrition
  • Consistent flow
  • Unbiased and representative sampling for better quality measurements

Intended for:

  • Pharmaceutical manufacturing (batch or continuous)
  • Biopharmaceutical production
  • Powder blending, homogenization, granulation, and compression processes

Intended for:

  • Pharmaceutical manufacturing (batch or continuous)
  • Biopharmaceutical production
  • Powder blending, homogenization, granulation, and compression processes

SSK Benefits:

  • Enables true real-time quality monitoring and decision-making
  • Eliminates sampling biases from traditional “thieving” methods
  • Supports faster time to product introduction (great for NPI)
  • Improves process understanding and knowledge
  • Strengthens process control and reliability
  • Avoids particle rearrangement, attrition, and recirculation
  • Ensures equal sampling probability (Fundamental Sampling Principle)
  • Works with PAT tools for immediate quality measurement, adjustments, and control
  • Tested with multiple formulations (e.g., Ibuprofen/Lactose/MCC blends, etc.)
  • Demonstrated stable NIR spectra during continuous operation
  • Supported by extensive scientific literature (2020–2024 studies)
  • Supported by SMEs from the Academia and CIS International

Our Value Proposition:

Technical Summary

  • The stream sampler with an approximate capacity between 8 - 100 kg/h
  • Wide range of material properties studied (Carr’s Index between 21 and 40)
  • Wide range of API concentrations (0.7 – 80% w/w)
  • Easy to clean and small in size
  • Avoid complex flow dynamics of the feed frame (avoids recirculation)
  • No need to install NIR or Raman inside the feed frame or use a long fiber optic probe
  • Adaptability to granulators, blenders, and multiple tablet compression machines, regardless of the feed frame
  • Variographic analysis – Sampling & Error.
