Products >> Esprayer Arrayer Models ES-3000 series Note: LCD monitor, keyboard, and mouse not included The Esprayer Arrayer is equipped with one capillary and can spot samples on multi-chips using a changer. Although the equipment is used mainly as a protein arrayer, it is still applicable to patterning deposits on a wider area. Description The Esprayer Arrayer is made up of a capillary head, a mask holder, a sample holder, a substrate changer(option), a laser, and a video microscope. Component Parts The capillary, the control software, the sample holder, the chamber Product Specifications Components Specifications High-voltage power supply V1 (spray voltage) 2.4kV- 24kV V2 (collimator voltage) 0.3-3kV Spray capillary glass (outer diameter Ø1.6mm, tip diameter Ø20-160µm), 1 capillary, various types and sizes Sample solution distribution delivery by syringe pump Substrate holder One substrate of slide-glass size (76x24mm) can be holded Mask glass or glass-epoxy resin material (ask for our standard size and pattern) Housing acrylic with ventilation inlet and outlet for dry air Dimensions of body 600mm(Width) x 600mm(Depth) x 800mm(Height) Weight of body Approx. 50kg Power supply AC115-235V, 250W Option capillary changer, substrate changer Applications Protein chip fabrication for quantification and characterization; protein fixation onto microfluidic chip; protein fixation to biosensor; patterning of cell culturing substrate; and patterning deposits of various samples. Micropatterning of two Fluorescent Dyes In the above illustration, two fluorescent dyes were sprayed with the Esprayer™ Arrayer in alternate rows of eight spots. The spots were then observed with the fluorescent microscope. Two dyes were spotted to the specific pattern without mixing. Principal features Uniform and highly accurate spotting Easy-to-form patterning High deposit efficiency Other features Efficient and time-saving in spotting numbers of protein chips Good at fabricating chips combined with micro channels Capable of forming multi-layers by spraying samples in the dry state Possible to combine with electric circuits Uniform and accurate spotting High-density patterning The Esprayer forms uniform and densified spots. The picture shows an example of 1,026 spots, approximately 100µm in diameter, uniformly affixed, which were adhered by spraying florescent colorants with Esprayer™ Arrayer, using a porous mask of 3x3x6 holes in 290µm in diameter and 400µm in pitch. The spotted diameter can be reduced to 5-6µm. Since the Esprayer uses a mask to spray, precisely positioned accurate spotting can be achieved. Moreover, as dried protein particles are collected and captured electrostatically, the spot forms uniform layers in a dry state. Easy-to-form patterning Patterning Depositing with the Fuence Logo Mask Patterning deposition by Esprayer™ Arrayer using the Fuence Corporate Logo Mask. The image on the left shows the mask itself, and the image on the right shows the electrosprayed deposit Rhodamine WT using the mask. Having been collected and captured electrostatically onto the substrate through a mask, the sprayed samples are deposited in the shape of the mask hole. Since the mask hole is possible to make designs with lines, curves, spots and combinations thereof, it is easy to form any deposition patterning of the user's choice. For a specific design required other than the standard masks ->Contact Us How to carry out Efficient Depositing Samples sprayed by the Esprayer™ Arrayer are deposited directly onto the substrate passing through the mask hole(s) without sticking to the mask. Therefore, even with minimal amounts, the samples are collected and captured on the substrate in such a way that costly samples are used to their maximum efficiency. Remarks: While the equipment is designed to perform various ESD tests, not all the results are guaranteed under different experimental conditions.
