From bench analytical separation to GMP-scale biopurification, CRS Scientific piston pumps are integrated into instruments solving real problems for scientists every day.
Sub-µL/min stability and 60 MPa pressure ratings make CRS-HP the workhorse pump behind isocratic, binary, and quaternary analytical HPLC systems used across pharma QC, environmental, and food safety labs.
Hardened sapphire plungers, redundant check valves, and intelligent compressibility correction enable CRS pumps to drive sub-2µm columns to their full performance envelope.
Bioinert PEEK and titanium flow paths protect biologics. Continuous rear-rinsed seals prevent salt crystallization, so high-conductivity gradients don't punish your seals.
From semi-prep purification of natural products to scale-up of API intermediates, the CRS-FB platform delivers reproducible volumetric flow up to 300 ml/min at 30 MPa.
Rugged dual-piston design, simple maintenance, and a price point that fits flash instrument BOMs — CRS-FB is the right pump for high-throughput purification environments.
Specialty chromatography modes demand specialty pumps. CRS supplies CO₂-rated pump heads for SFC and balanced multi-pump configurations for simulated moving bed systems.
CRS-LP large-bore pumps are integrated into downstream bioprocessing skids, providing reliable buffer and product flow up to 1 L/min with industrial communication protocols.
Low-volume, MS-friendly pump configurations with metal-free wetted parts options serve as the front end for high-sensitivity LC-MS/MS systems.
Beyond chromatography — CRS piston pumps are deployed as reagent metering pumps in continuous flow synthesis, PET radiochemistry, and process analytics.
If you can measure it, we can probably pump it. Let's discuss your fluidic challenge.
