HPLC Sample Prep | Filtration
The power of simplicity: Filter 8 HPLC samples simultaneously
Clarification by filtration to remove particles from samples decisively impacts the separation efficiency of your HPLC column and thus the reliability of your results. The most common filtration method is to use syringe filters. They’re great if you have a small number of samples. But when you have to filter many samples, this can quickly turn into a tedious – and strenuous – chore.
Claristep® filtration system
Claristep® is a filtration system designed to save you both time and effort. Thanks to the patented design of the Claristep® station, you can now quickly and easily filter up to eight 60 μL to 600 μL HPLC samples in parallel using one hand – without the need for AC power, vacuum pumps or syringes.
Optilock, a unique Sartorius feature, provides flexibility for volume adjustment and locking – reliably preventing accidental volume changes during pipetting.
Minisart® - The right choice for reproducible & clean sample preparation – every time
If you want to filter HPLC samples for reproducible and clean particulate-removal, using syringe filters is the method of choice. Featuring pore sizes of 0.2 μm or 0.45 μm and a selection of special membrane materials and diameters, the proven Minisart® with a polypropylene housing reliably removes particles, without adding extractables or leachables to your sample. And each Minisart® RC pack now comes with a lot-specific HPLC purity certificate.
Minisart® syringe filters
Minisart® RC with a regenerated cellulose membrane has been optimized for aqueous solutions and solvents. Its especially high chemical compatibility permits it to be used in a wide variety of applications. Minisart® RC is resistant to DMSO, other amides, ketones, esters and ether compounds.
Minisart® NY with a nylon membrane and Minisart® GF+NY with the purest glass fiber prefilter and nylon membrane are optimally designed for the filtration of alkaline aqueous solutions and solvents. Their unique purity compared with other common polyamide membranes ensures clean samples.
Minisart® SRP with a hydrophobic PTFE membrane has been optimized for filtration of especially aggressive chemicals. The membrane without any coating whatsoever guarantees absolutely leachable-free clarification of samples.
