The SPM+ OEM sequential microdispenser is a high-volume version of the SPM, designed for applications that require precise dispensing of larger liquid volumes.It combines accurate dosing, low pulsation flow, and the flexibility of handling multiple fluids in one compact OEM-ready device.
General
The SPM+ integrates a zero dead volume multi-port valve and is optimized for high-volume syringes up to 5 mL. It delivers smooth, stable flows from microlitres to millilitres, with excellent cleanability and minimal carryover. This makes it ideal for analytical devices, clinical diagnostics, and process automation.
Key Features
- High-volume dosing up to 5 mL
- Zero dead-volume valve for multi-fluid handling
- Low pulsation continuous flow
- High cleaning efficiency with minimal carryover
- Compact and easy to integrate in OEM instruments
Applications
- Larger-volume reagent dispensing
- Automated sampling and dilution
- Continuous perfusion with smooth flow
- Multi-fluid sequencing in diagnostics
Also available in other OEM versions: SPM (low-volume), SPM HD (high-precision), and SPM+ HD (high-volume, high-precision). For a standalone instrument, see the LSPone high-volume laboratory syringe pump.
