Note: Our warranty terms quoted for this instrument apply to mainland UK customers. For clients outside of this locale, please enquire at point of sale.
hplc4sale.co.uk (Jaytee Biosciences Ltd) warranty all reconditioned instruments for a pre-agreed period. This period can be from 30 days to 1 year from the date of installation / delivery of the instrument. Generally newer equipment has a longer warranty than older equipment.
Additional warranty periods can be negotiated at the time of purchase if required.
The list below outlines the items covered by our warranty:
This Waters Alliance 2695 Separations Module consists of a quarternary pump, degasser and a variable volume autosampler, capable of injecting from 5 x 24 2ml vials.
The four solvent in-line degasser offers a high efficiency alternative to helium sparging for the removal of dissolved gases from HPLC mobile phases.
Designed for a wide variety of applications, this reliable tool is a common work-horse in most analytical and contract labs. Built to meet labs rigorous requirements or routine analysis, suited to Pharmaceutical, Food Safety, R&D, Chemistry, Environmental or Quality Control labs. Featuring a large, easy-to-use LCD interface, take advantage of the quick autostart and optimize your methods with a simple push of a button. Manage up to 120 industry standard vials with the built in autosampler

The column heater provides accurate temperature control which enhances chromatographic results by creating a consistent separation environment for method reproducibility. It has a capacity of two columns (8mm ID mx, 30cm length max). Heats up to 60°C, programmable in 1 °C increments.
The 2487 detector is a 2 channel, tunable ultraviolet/visible (UV/Vis) detector that operates in single or dual wavelength mode, allowing spectrum scanning using a flow cell or a cuvette, providing RatioPlot and MaxPlot functions.
Single Wavelength Mode
Single wavelength is the default mode of operation for the 2487, supporting monitoring of a single wavelength from 190nm to 700nm, settable in 1nm increments on Channel A.
Dual Wavelength Mode
In dual wavelength mode, the detector monitors on Channel A and Channel B. The sampling frequency is reduced from 10Hz to 1Hz, limiting use of this mode to more standard chromatography, where peaks span at least 20 seconds to enable full characterisation of a peak.
Stand-alone programmability - Stores up to 10 user defined programs (or methods) consisting of up to 16 programmable timed events and 2 threshold events each.
Integral erbium calibration reference - ensures wavelength accuracy
Automatic second order filter - Automatically enganged for wavelengths 370nm and greater and removed for wavelengths 369nm or less.
Spectrum scan and storage - supports spectrum scan, display, subtraction, storage and playback, in addition to standard tunable absorbance and UV/Vis functionality.
Cuvette qualification - facilities qualification of the detector by insertion of a standard in a cuvette without breaking any fluidic connections.
Cuvette sample analysis - allows the spectrum of any sample placed in the cuvette to be recorded.
Method editing and storage - supports basic method programming, storage and retrieval from the front panel
Full diagnostic capability - supports built in diagnostic tools to optimize functionality and performance.
Backward compatibility - operates as a 486 detector with Millenium Chomatography manager version 2.1n and lower, PowerLine, ExpertEase and other Waters products connected via the LAC/E interface using the IEEE-488 bus.
