ViaLabel® is a division of InfoSight Corp®. "We Barcode Difficult Stuff tm" Providing state of the art bar code solutions for automatic identification of laboratory samples.Our technology produces robust , high contrast , industry standard bar codes on sample containers such as vials, slides or cassettes without the use of adhesive labels.
All markings except cassettes are done by lasers on white patches applied to the sample container. The coatings are specially formulated such that they turn dark black upon laser marking. This approach ensures high contrast ( PCS) bar codes when compared to inherent laser surface modification techniques.
Cassettes are marked by applying a specially formulated black patch onto the cassette surface and then laser ablating away the undesired black areas. The black patch has high adhesion to the (slippery) cassette surface. See Patent USP6518542.
All of our solutions provide codes which survive:
Cryogenic temperatures ( long term and cyclic)
Xylene and Most Solvents ( also tested long term in Surgipath Clearene®, Surgipath Sub-X®, Fisher Citri Solv™, and Richard-Allan Clear-Rite ™3)
Alcohols ( Methyl and Ethyl)
Our Glass Vials survive:
Temperatures up to the melting point of the glass
Please scroll down through the following examples.
Weighing Pan with sequential bar coded tab- Mark survives temperatures up to those which melt the pan.

There are two Approaches
1.We coat white (laser blackenable) patches or black (laser ablatable) patches on the containers , mark them with sequential bar codes and ship the marked containers to you. You then link the instance container to its database when the container is filled in your laboratory. See a White Paper " The Case for Standby Preprints"
blackenable) patches or black (laser ablatable) patches on the
containers and ship them to you. You utilize a laser marker to
image specific sample data onto the vial either before or
after it is filled with the laboratory sample.
