Abstract
A device for rinsing sample processing components of an analytical instruments including an inlet coupleable to a fluid source, an outlet coupleable to sample processing components of an analytical instrument, and a fluid reservoir between the inlet and outlet. The device includes a heater coupled to the fluid reservoir and the fluid reservoir includes at least two reservoir chambers connected in series and separated by a restricted passageway.
Claims12
An analytical instrument comprising:
- a cabinet;
- sample processing components operably coupled to the cabinet;
- a fluid rinse device including an inlet and an outlet, the inlet being coupleable to a fluid source and the outlet being coupleable to the sample processing components;
- wherein the fluid rinse device includes a reservoir having at least two reservoir chambers connected in series and separated by a restricted passageway and a heater being disposed about an exterior of each reservoir chamber for heating fluid in the reservoir chamber;
- a valve assembly coupleable to a pressurized carrier source, the fluid rinse device, and sample processing components;
- and
- a controller coupled to the valve assembly to intermittently supply fluid to rinse the sample processing components.
