CHRONECT SPH1299™| Pump
Superior UHPLC with SPH1299
Robust, proven concept guarantees strong performance
The complete system is optimized for UHPLC, dead volumes are minimized and all materials are designed to work at high pressures. At the heart of the UHPLC is Spark Holland‘s SPH1299. This pump is a guarantee of robust, state-of-the-art UHPLC performance. It delivers ultra-precise UHPLC gradient flow up to 18,850 psi (1,300 bar). Automatic compressibility compensation, modern prime function and easy maintenance are making the pump extremely user-friendly.
SPH1299 is based on the proven concept of linear drive technology for two pairs of serially coupled pump heads. Each of the four pump heads is driven and controlled individually. This results in maximum precision for flow control and pulse reduction. Intelligent, novel algorithms ensure stable and precise flow regardless of solvent compressibility, pressure and flow rate. The result is solvent gradients with exceptional precision in both composition and flow rate; the SPH1299 ensures robust and accurate UHPLC gradients.

SPH1299™ is based on the reliable, proven concept of linear drive technology for two pairs of serially coupled pump heads. Each of the four pump heads is individually driven and controlled. This generates maximum freedom for flow control and pulse reduction. With intelligent novel flow control algorithms this freedom has been fully explored to create a stable and accurate flow, independent of solvent compressibility, pressure and flow rate. This results in solvent gradients with exceptional precision of both the solvent composition and the flow rate; i.e. in robust and precise gradient UHPLC.
Easy and economic
SPH1299™ has active piston backwash for longer lifetime of piston seals. This is very effective to increase up-time of the pump, but eventually a seal will need replacement. With this in mind, the pump head has been designed to facilitate easy disassembly and seal exchange. No need to remove covers or take the pump out of the UHPLC stack. No need, also, for expensive exchange of entire pump head/drive assemblies! Simply disconnect the pump head from its drive, remove the piston and replace the seal. In just minutes!
A novel automatic priming concept fully automates the cumbersome priming procedure. A built-in prime pump aspirates solvent through the pump heads when starting with empty solvent inlet lines. No need to help your pump with a syringe for awkward manual solvent aspiration. Using an electrically actuated purge valve, SPH1299™ can truly prime and purge all by itself in just a few minutes!
