LEAP - Model X-Press -Automated Sample Filtration System
LEAP has developed a `Press` accessory,LEAP X-Press, for the PAL which allows samples to be filtered reliably and repeatably. It does not require external pneumatics, but compress the filter chambers. Samples can be processes in batch mode or `just in time` before direct injection to the LC valve. The LEAP X-Press can be used for stand-alone operation with an optional foot.
Significant Markets
Any labs who are doing High Performance Liquid Chromatography (HPLC) or more significantly, Ultra High Performance Liquid Chromatography (UHPLC) analysis. It is imperative that particles are eliminated to avoid blockage of HPLC lines and columns. This filtering technique let you prepare samples in one third the time required by other methods. Automation of the filtering step has NOT been possible in a reliable fashion till now.
Filtration on a single disposable for a great variety of situations.
- Samples can be filtered just before injection onto a UHPLC system.
- Plant extracts and any solutions with particles
- Ease of use Filtering and storage vial allows you to process sample loads in one-third the time
- Wide range of membranes Suits a variety of sample types
- Available in 0.2 and 0.45 μm pore sizes to meet specific sample application requirements
- Compatible with all major autosamplers Allows you to speed processes
- Fewer consumables required Lowers Costs by up to 40 percent
- Slit septa cap - Enables Mini-UniPrep use with current robotics on HPLC instruments for high throughput automation
- Slit septa cap - Increases needle longevity Eliminates coring problems associated with repeated sampling
- Slit septa cap - Durable yet flexible and has been specially designed for instruments with sensitive sampling needs
The self-sealing septa of the UniPrep allows for repeated injections: Prevents evaporation and maintains sample integrity. Whatman Mini-UniPrep Syringeless Filters offer a highly efficient, simple alternative for removing unwanted protein prior to HPLC/MS analysis. Ideal for performing analytical characterization in drug research, the method utilizes acetonitrile precipitation and filtration by compression to remove protein from plasma, serum, whole blood, and other biological fluids. It is a single tube method that saves time and eliminates the manual transfer steps which make spin clarification problematic.
