The SlideTrack ESPO direct to slide printer enables laboratories to print chemical-resistant text and bar codes directly to slides on demand using thermal transfer printing technology. Given the device’s small size, printed slides can be produced right at the microtomy station. The printer has a capacity of 200 slides (two 100-slide magazines) and it is capable of printing charged and/or uncharged slides at a rate of 20 per minute. With three print modes, the user has the ability to choose between single or batch printing, and the front-loading feature allows for single-slide printing for worry-free control slides. The Slide-Track ESPO from General Data Company is designed to help laboratories automate the process of slide printing.
