Refurbished Tulip Diagnostics LisaWash 4000 ELISA Microplate Washer

The Tulip Diagnostics LisaWash 4000 ELISA Microplate Washer is a laboratory instrument designed to automate the washing steps involved in enzyme-linked immunosorbent assay (ELISA) procedures. It is used in diagnostic laboratories, hospitals, research facilities, biotechnology laboratories and other settings where immunoassay testing requires consistent removal of unbound substances from microplate wells.

ELISA is a widely used analytical technique for detecting or measuring specific antigens, antibodies and other target substances in biological samples. During an ELISA procedure, washing is an essential step because it removes residual reagents and unbound components that may interfere with the assay results. A dedicated microplate washer helps standardize this process and reduces the need for repetitive manual washing.

The LisaWash 4000 is designed with a three-channel washing system and supports multiple plate-washing configurations. Manufacturer information describes programmable wash volume, wash cycles and soak time, together with plate washing, strip washing and row-skip washing functions. These capabilities provide flexibility for laboratories performing different ELISA protocols.

The instrument features a digital display and a control keypad for operating the system and selecting available washing programs. Its enclosed plate-washing area accommodates the washing mechanism and microplate during operation. The design is intended to help laboratory personnel carry out repeatable washing procedures while reducing manual handling and improving workflow efficiency.

According to available product documentation, the LisaWash 4000 provides multiple plate-setting options for different well shapes, including flat-bottom, U-bottom and V-bottom configurations. It also supports plate, strip and row-skip washing modes, which can be useful when processing full microplates or selected rows and strips.

Another useful feature is the ability to store multiple washing programs. Available documentation describes storage for up to 100 wash programs, allowing users to configure and retrieve protocols according to their laboratory's testing requirements. Wash and waste bottle monitoring features, including liquid-level detection and alarms, are also described in product documentation. The instrument's built-in incubator is listed among its features; its present operational status should be verified before purchase.

The LisaWash 4000 can be a practical addition to laboratories conducting routine immunodiagnostic testing, academic research, biotechnology studies and assay development. By automating the washing stage, it can help reduce repetitive manual work and improve consistency between runs when operated with validated protocols and appropriate maintenance.

For laboratories seeking pre-owned equipment, a refurbished LisaWash 4000 may offer a cost-conscious alternative to purchasing a new instrument. Before listing or purchasing the unit, it is important to verify its operational condition, washing manifold, tubing, pumps, bottle sensors, display, keypad, available accessories and compatibility with the intended assay protocols.

This instrument is intended for laboratory use. Actual performance depends on the instrument's condition, the selected washing program, the assay protocol and proper maintenance. Refurbished units should be tested before being placed into routine laboratory service.
