An automatic plate washer is a medical device specially designed to clean microplate plates, and is usually used with a microplate reader. Through the precise programs, the automatic plate washer can thoroughly clean the residue on the microplate plate, avoiding the errors and troubles that may occur in manual washing, and improving the accuracy of the test results. It is mainly used in experiments such as enzyme-linked immunosorbent assay (ELISA), where there are residual detection samples, reagents, and non-specific conjugates on the microplate plate, and the automatic microplate washer can effectively remove these residues, reduce background signal, and improve the accuracy and reproducibility of the experiment.

Modern microplate washers are highly automated and intelligent, automatically recognizing the type and number of plates and automatically adjusting the cleaning program to different needs. The development of this technology has significantly improved the efficiency of the microplate washer, while effectively reducing the errors caused by manual operation, ensuring a more accurate and reliable cleaning process.

Welso WPW300 Automatic Microplate Washer is designed to be compact, easy to operate, highly reliable, and efficient for a wide range of microplate formats. To better meet the needs of multi-level users, the WPW300 is equipped with a number of enhancements, including bottom flushing, two-point aspiration, vibrating plate function, liquid volume adjustment, and waste residual alarm system. Its intuitive and user-friendly touchscreen display allows users to easily master and control the plate washing process, ensuring more thorough washing, providing reliable and accurate support for experiments, and is ideal for microplate cleaning applications such as enzyme-linked immunoassays.

Let us take a look at the features of this washer:

●Large LCD display：Equipped with menu operation interface with easy operation and user-friendly experience.

●Support full plate or stripes cleaning mode：User can choose cleaning mode according to experiment requirements.

●Adopt two fluid suction design：Make sure that the residual volume of each well after washing is less than or equal to 1 μL, which greatly reduces the experimental error.

●Equipped with a microplate bottom rinse function: ensures thorough cleaning without dead spots.

●With shaking and immersion functions: effectively reduce the interference adsorption in the reaction process and improve the accuracy of experimental results.

●The cleaning fluid pressure can be fine-tuned: it can adapt to various special cleaning needs and has strong flexibility.

●Adjust cleaning time and tube cleaning function: effectively prevent the tube from being blocked and ensure the long-term stable operation of the equipment.

●Compatible with a variety of low-profile microplates such as flat bottom, U-bottom, V-bottom: wide applicability.

●Can store more than 100 programs: easy to load programs and improve experimental efficiency.

●Equipped with waste liquid overflow alarm function: real-time monitoring of use safety, to avoid the loss caused by liquid overflow.
