Malvern Panalytical Ultra-Micro Cell for Nano Series ZEN2112

The Ultra-Micro Cell (ZEN2112) is a low-volume quartz batch cuvette designed for particle size and molecular weight measurements on Zetasizer Nano series systems. It enables measurements from sample volumes as small as 12 microlitres (with backscatter optics) up to 45 microlitres, and is suitable for use with both aqueous and non‑aqueous solvents and dispersants. The cell’s high optical quality and specially modified Hellma design make it appropriate for measuring small, poorly scattering samples such as proteins.

Key Features:

• Minimum sample volume: 12 µL (Zetasizer Nano S/ZS/ZSP with backscatter optics)
• Maximum sample volume: 45 µL (filling chamber capacity)
• Sample chamber dimensions: 3 mm × 3 mm × 5 mm (W × D × H) with 10 mm circular top aperture
• Construction material: Quartz body with polypropylene cap
• Number of optical windows: 3

Advantages:

• Enables accurate size and molecular weight measurement of very small sample volumes, reducing sample consumption
• High optical quality suitable for small, poorly scattering samples such as proteins
• Compatible with a wide range of aqueous and non‑aqueous solvents and dispersants
• 3 mm × 3 mm path geometry simplifies filling and reduces air entrapment during sample loading
