The BioRead-A6DF Deep Focus Scanner has been developed for clients whose scanning needs might require reading of tubes seated a greater distance than usual from the screen. This can happen with some racked tubes due to the build up of frost around the tubes, when stored frozen. The DF scanner can read tubes sat fully in the rack or slightly elevated, up to several millimeters above it. Hence the "deep focus" quality of this instrument. With only a few minutes needed for configuration of our DataPaq™ software, you'll be ready to start scanning in no time at all.
The Biosero 2D barcode scanners are also available with a cryoprotective coating which prevents condensation build-up on the underside of the window. Condensation can prevent the scanner from reading the 2D barcodes properly. Therefore, if you will be regularly scanning tubes straight from the freezer, the cryoprotective proofing could be the solution for you. Our method for eliminating condensation uses a special coating on the scanner window, no extra electrical components are required. This increases reliability and significantly decreases the cost. Additionally, some manufacturers use fans to remove the condensation which could unnecessarily speed up the thaw-rate of the precious samples.
The cyroprotection option has been extensively tested in real-life situations and proven to reliably work. Some of our customers comment on the cryoprotection option:
"We have used the scanners to check our whole compound library and the anti condensation coating meant that we could take plates straight from the freezer to the scanner without any problems."
"After using the Ziath scanner for months now we can say that it does a very good job. Coming from a -80°C freezer empty racks can be scanned right away without any pre-treating or condensation coming up while the process. When the racks are filled, a quick touch in an ethanol bath is enough to remove external ice to reach the same good results. Further the Ziath device shows great reliability concerning its hardware as it does not show any changes in the quality of its parts after using it with deep cooled racks for nearly a year now."
Typically a rack contains a linear barcode. The optional Linear Barcode Scanner will automatically scan the linear barcode on the side of the rack and enter this data into the output along with the 2D tube barcodes. The unique design of the linear scanner means that the it can be mounted onto the 2D scanner unit without any screws needed. Available at order time or to be user installed onto an existing 2D scanner; it's easy to install and the installation of the software is simple.
