The μPulse TFF System consumable modified polyethersulfone (PES) chip variety packs provide a convenient and cost-effective way to evaluate multiple molecular weight cutoffs (MWCOs) and identify the optimal membrane for your application. These consumable chips are designed for compatibility with the μPulse TFF System and enable direct comparison of retention, concentration, and filtration performance across a range of cutoffs.

Each variety pack includes four consumable chips, with one chip per MWCO, allowing streamlined method development without committing to a single membrane type.

Available Variety Packs:

Variety Pack A
Multi-Cutoff: 5, 10, 30, & 50 kDa
Pack of 4 chips

Variety Pack B
Multi-Cutoff: 30, 50, 100, & 300 kDa
Pack of 4 chips

Variety Pack C
