Worth knowing before you order
What ships is the pump module or modules, the UV detector, the manual six-port valve, the software, a power cord and the test certificate. The column is not included and has to be chosen against the method. The fluorescence and refractive index detectors are separately quoted options, not alternatives supplied in the box, and there is no autosampler in the base system, so every injection is made by hand at the valve. The two builds differ only in pump count - one pump for isocratic work, two for binary gradient - which is also why the gross weights differ by 15 kg. The detector drift is printed as 2×10-4 AU with the exponent flattened in the catalogue; read it as 2 × 10⁻⁴ AU and have it confirmed on the quotation. The manufacturer states the software is compatible with GLP and 21 CFR Part 11 for electronic records and signatures; Part 11 compliance is demonstrated by the user's own validated process and procedures, not by anything shipped with an instrument.Specification
