Unchained Labs PUNK Dynamic Light Scattering DLS Protein Sizing System Analyzer

Manufacturer: UNCHAINED LABS

Model: pUNk

Description:

The pUNk puts a new spin on dynamic light scattering (DLS).
It allows you to measure the hydrodynamic size, size distribution and aggregate population of a protein much faster and with less effort. If you value high sensitivity, you can check it off with the pUNk's unique optical design. Get more done with the smallest, fastest and most user-friendly protein sizing system.

Key features:

• 5 µL sample size
• Percentage aggregation
• Protein size
• Polydispersity
• HPLC compatible

Other data:

Molecular weight range: 192 Da (e.g. caffeine) - 25 MDa
