Presi Poly'Vac – Precision Vacuum Impregnation for Flawless Samples

Maximize penetration, minimize air inclusions: The Presi Poly'Vac system is the professional solution for the demanding cold mounting of porous, brittle, or complex specimens.

In metallography and material science, ensuring the mounting resin completely penetrates the sample is critical for the final quality of the cross-section. The Poly'Vac was developed to evacuate air from the pores and cracks of your samples, drawing the resin (preferably epoxy) deep into the structure. The result is a perfectly supported sample without edge detachment or voids.

Why use Vacuum Impregnation with Poly'Vac?

Standard mounting methods often leave air bubbles trapped in cavities or along sample edges. This leads to unstable mounts and compromised analysis. The Poly'Vac system automates the evacuation and pouring process under vacuum, ensuring even the finest cracks are completely filled.

Key Benefits at a Glance:

• Optimal Sample Support: The vacuum forces resin deep into pores—ideal for ceramics, composites, or electronic components.
• Bubble-Free Results: Effective degassing of the resin prevents distracting inclusions within the microscopy field of view.
• Precision Control: An intuitive color touchscreen allows for exact programming of vacuum levels and cycle times.
• Integrated Resin Dispenser: Allows for clean pouring of samples directly inside the vacuum chamber without breaking the vacuum.
• Compact All-in-One Design: The vacuum pump and chamber are housed in a single ergonomic unit, saving valuable lab space.

Technical Features:

• Vacuum Performance: Achieves a vacuum level of up to -90 kPa.
• User-Friendly Interface: Programmable timers (from one minute to several hours) for reproducible processes.
• Flexibility: Compatible with various mounting molds (Teflon, Silicone, KM rings).
• Ready to Use: Includes a starter set with protective films, tubes, and nozzles for immediate operation.

The Ryf Recommendation:

We particularly recommend the Poly'Vac system for laboratories frequently working with porous materials or layered systems. The combination of vacuum degassing and controlled pouring significantly saves time and reduces the reject rate during sample preparation.
