Stericup and Steritop Vacuum Filter Cups
For Volumes from 150 mL to 1L
Stericup and Steritop filter units are high performance filter units ideally suited for sterile filtration of cell culture media, buffers, and reagents. These filter units are available with a selection of membranes to best meet application needs.
- Sterile and ready-to-use
- Fast flow
- Low protein binding
Fast Flow with High Throughput
The asymmetric pore structure of the Millipore Express PLUS membrane gives it greater throughput than other membranes. This can be especially important when filtering serum or other protein-aqueous solutions.
Low Binding
Membranes with low protein binding ensure that key growth factors and proteins are not absorbed into the filter. Millipore Express PLUS membrane provides low protein binding with fast flow rates. For lowest protein binding, choose a device with Durapore (PVDF) membrane.
47 mm membrane disks with a 0.22 µm pore size were challenged with DMEM with 10% PES.
Membrane disks with a 0.22 µm pore size were offered a 1 mg/mL solution of 125l labeled lgG. The chart shows protein binding after incubation (normalized to membrane surface area).
