Technidyne Pulmac MasterScreen™ Fiber Contaminant Analyzer

See what’s hiding in your pulp

The Technidyne Pulmac MasterScreen™ gives you a fast, definitive answer to the question every mill asks: what contaminants are in my pulp? It mechanically separates fibers from stickies, dirt, shives, vessel cell elements, plastics, and hot melts at low consistency. 

Contaminants are automatically deposited onto filter paper, giving you a clear visual record of what’s in your furnish — no guesswork, no interpretation required. 

Find the source of contamination — fast

When contaminants show up in your finished product, the MasterScreen™ helps you trace them back to the source. Sample at any point in your process — digesters, cleaners, refiners, grinders, repulpers, screening systems — and the MasterScreen™ isolates what’s getting through. 

The result: fewer customer complaints, less downgraded product, and a process you can troubleshoot with evidence instead of guesswork. 

Explore the MasterScreen™

We’ve been supporting the pulp and paper industry for decades, developing equipment that helps identify, analyze, and reduce contaminants in pulp. 

Across our portfolio, the MasterScreen™ stands out as a low-consistency screening device that mechanically separates fibers from contaminants such as stickies, shives, dirt, and vessel cell elements. For customers looking to assess fiber quality beyond contamination, the Z-Span Tester is a natural next step, allowing precise measurement of fiber strength and bonding properties. 

Be sure to explore other fiber and pulp testing solutions from across the Industrial Physics portfolio. 

Learn more and get insights

Over the years, we’ve gathered insight into effective fiber screening and contamination analysis.

We share much of this knowledge in our knowledgebase. For example, if you’re new to pulp evaluation, check out Pulp Evaluation: Application Information. Or, for a deep dive into standard pulp testing methods, see the TAPPI T 275 article. 

These resources will help you maximize the MasterScreen™’s performance, troubleshoot issues, and understand how contaminant data can impact overall pulp quality.
