Malvern Panalytical MPT-2/MPT-3 FOLDED CAP CELL SILICON TUBE ZEN4040

Disposable folded capillary cell and related accessories for zeta potential and particle size analysis on Malvern Panalytical Zetasizer systems. The folded capillary cell is a disposable, plug-and-play polycarbonate capillary with gold-plated electrodes designed for zeta potential measurement and compatible size measurements. MPT-2 and MPT-3 are autotitrator accessories that automate titrations of pH, conductivity or additives for Zetasizer instruments. The ZEN0040 is a 40 µL disposable solvent-resistant micro cuvette optimized for size measurement using 173° (NIBS) optics. Silicone tubing is included among materials used in Malvern Panalytical accessory kits for fluid handling and sample delivery.

Key Features:

• System compatibility: Zetasizer Nano ZSP, ZS, Z, ZS90
• Folded capillary cell sample volume: 0.75 mL
• Folded capillary cell materials: polycarbonate body with gold-plated beryllium‑copper electrodes
• Folded capillary cell operating temperature: 0 °C to 70 °C
• ZEN0040 disposable micro cuvette: 40 µL volume; supplied with 100 caps per pack
