Reducing sample loss. After filtration the sample is ready to use in most standard autosampler. The pre-slit cap ensures easy and clean transfer of sample. 5 different septa material, PP vial with Ø 12 x 33 mm, Filtering capacity 0.48 ml, dead volume <30 µl, maximum operating temperature 50 °C...
MF-Millipore™ membrane, mixed cellulose ester, 47 mm
MF-Millipore™ Membranes have a biologically inert mixture of cellulose acetate and cellulose nitrate. The MF-Millipore™ filters without Triton® surfactant have a lower water extractable content compared to the standard MF-Millipore™ filters and contain a minimal amount of wetting agent.
Features & Benefits:...
Steritop™ Filter units
For fast and uncomplicated sterile filtration of aqueous solutions in bottles with narrow or wide threads, the Steritop™ bottle top filter with large filter surface is ideal. Inside the funnel there is a small tab with which you can securely attach a separately available pre-filter during filtration. In order to provide optimum protection against contamination, the thread of the bottle cap is slightly set back....
Durapore® Membrane Filter
Durapore® PVDF membranes are characterized by high throughput and high flow rate. To maximize recovery and minimize interaction with your sample, the membrane has very low protein binding.
Features & Benefits:
- Can be sterilized by ethylene oxide and gamma irradiation
- Available in different pore sizes
Membrane Filters, nylon
Recommended for filtration, sterilisation and clarifications of mobile phase in HPLC processes with aqueous, alkaline and organic samples

- High non-specific adsorption, high mechanical stability
- Qualified for many solvents and alkaline solutions, pH range 3-14
- Maximum temperature 134 °C
Millipak® Filter
The stacked-disk format of Millipak® filter units eliminates the risk of fiber release from downstream support material.
Features & Benefits:
- No risk of membrane cracking as the 0.22 µm membrane is supported by a rigid plastic disc with channels
- As the membranes are welded onto the support disc, the risk of contamination is considerably reduced
- Minimum dead volume thanks to the large filter surface
MF-Millipore™ membrane, mixed cellulose ester, 25 mm
MF-Millipore™ Membranes have a biologically inert mixture of cellulose acetate and cellulose nitrate. The MF-Millipore™ filters without Triton® surfactant have a lower water extractable content compared to the standard MF-Millipore™ filters and contain a minimal amount of wetting agent.
Features & Benefits:...
MF-Millipore™ membrane, mixed cellulose ester, black
MF-Millipore™ Membranes have a biologically inert mixture of cellulose acetate and cellulose nitrate. The MF-Millipore™ filters without Triton® surfactant have a lower water extractable content compared to the standard MF-Millipore™ filters and contain a minimal amount of wetting agent.
Features & Benefits:...
Microcon®
Solutions of any macromolecules, simple and efficient, desalt and concentrate. Suitable for any centrifuge holding 1.5 ml tubes.
Features & Benefits:
- Even with diluted solutions the recovery is more than 95%.
- Reverse spin to maximize recovery even in the smallest sample
- Storage of filtrate or concentrated sample, very easy in standard microcentrifuge tubes
- concentration factor up to 100 x
Membrane Filters, Cyclopore™, PC
Membrane filters Cyclopore™ polycarbonate are true pore size microporous membranes featuring the sharp cut-off and reproducible microfiltration characteristics of track-etched membrane filters.
- Low affinity for stains improves visibility under a microscope
- Low protein binding minimizes sample loss of proteinaceous samples
- Narrow pore size distribution and high pore density support rapid surface capture of analyte
