Using Pop Bio’s advanced image mapping technology*, the high sensitivity sensors in the
Vü can easily capture low output blots to provide a truly outstanding image.
Easy input, incredible output
Just place the blot (up to 10cms x 10cms) in the marked position on the tray and push into Vü with your finger. The Vü immediately recognises the thumbwheel setting and adapts to the blot size or application type.
Depending on your sample type, your image will appear in seconds or minutes ready for you to print or analyse. No fuss, no hassle, no drama, no camera, lens or filters to worry about. No sensitivity issues, no focussing needed. Just the best image you have ever seen - whether it is of a faint band or a high signal output blot

The latest CMSO Technology
Instead of a camera, the Vü’s head unit contains a linear array of high sensitivity CMOS sensors; moved in close proximity across the sample, backwards and forwards multiple times to collect the light output. The position and output level of the light emission is measured, with increases or decreases recorded. Once the Vü’s head unit has collected enough light to form an image (just 60 seconds for fluorescence and 2-5 minutes for chemiluminescence wester blot), the device automatically sends it to a device for viewing – thanks to a fully automatic imaging process controlled by the embedded intelligent software.
The CMOS Advantage
It is well known that CMOS sensors outperform CCD’s in most applications such as in fluorescence and chemiluminescence where there is a visible light output. Also a very important feature of a CMOS sensor is the incredible low noise as compared to a CCD. Of course CMOS technology has advanced significantly in the last few years ( just take a look at your mobile phone which uses the same technology) and that is why in the Vu systems we are using the very latest variants to produce high end systems at significantly lower prices than conventional CCD based units. CCD systems are really a throw back to the past – it’s time for change.
Super high resolution as standard
The Vü-F can image samples using UV, blue light or white light. The sensor set up uses an amazing 90m pixels of resolution to collect a high end image. Images are saved as 16bit TIFF or can be printed directly from the interface. To make the images easier to handle we output them to a more manageable 12m pixels at 300dpi – still more than enough to make large poster size prints with no loss of detail or data.
Imaging Superiority over CCD
When it comes to chemiluminescence the Vü-C really does excel. With over 51m pixels of resolution then you can expect high end images. Again to make them more manageable we output images at 2.34m pixels which can still produce a high quality poster image. Not only does the Vü-C image the blot itself it can also be set to image coloured or black/white markers. All of this is setup using the simple thumbwheel selector system found in the Vü range. Crucially, because of the high performance CMOS sensors the system produces images with virtually zero background without the need for any expensive Peltier cooling which is necessary on a CCD based system.
The Vü software is used to collect, save and print images - and it also provides access to
the system set up menus. The Vü processor creates the image and sends it to a network
via and ethernet or WIFi connection. Alternatively, Vü can be connected to a stand-alone
The Vü software is compatible with any computer running Windows 7 or higher. The Vü software also has hidden setup functions that can be accessed by a qualified person to be able to make further adjustments to the operation of the Vü system.
