| Accessory Showcase |
Flushing or "washing" the syringe and valve can be essential. The selection of solvents and the number of washes can be of paramount importance. Although it may seem obvious, it is worth stating that washing with ineffective solvent(s) is useless. There are many factors that will influence the effectiveness of the rinse, strength and polarity among them, but there are no hard and fast rules that apply to every case, so the end-user/chemist must be sure to choose solvents that will get the job done. The valve material and syringe type can also influence carry-over.
Here are some options LEAP offers for washing the valve including the latest the DLW

Other Accessories for PAL Robots
LEAP strives to find total solutions for analytical lab automation by automating analytical processes for small and large molecules in extracted liquids, solids, and recently in human, animal and plant tissues. We provide the precise robotics and efficient sample prep required by modern measurement techniques such as MALDITOF mass spectroscopy. Our newest specialty customization of CTC Analytics’ PAL features small workstations that can perform complex liquid handling tasks including HPLC-Purification, SPE, filtration, weighing, heating and stirring. They can be configured as stand alone units or integrated for “just in time” sample prep for LC-MS or GC-MS analysis.
LEAP provides automated workstation instrumentation solutions based on the LEAP CTC PAL X, Y, Z syringe only autosampler robot from LEAP Technologies. This extremely flexible, precise, and adaptable liquid handling robotic platform is available in a variety of lengths and options depending on the requirements of your sample preparation and injections for your UHPLC, LC or GC chromatography.LEAP offers full support and service for the PAL platform in addition to being able to write custom macros, cycles, and scheduling to your applications. Please contact LEAP Technologies on how we can help you get maximized throughput with flexible pipetting automation solutions.
