These plastic containers in which UltraGAPS™ Coated Slides are shipped also function as storage containers for printed arrays. The orange colored plastic has low transmittance in the 500 to 700 nm wavelength range which helps protect Cy®3 and Cy®5 dyes from photobleaching. These rigid plastic containers do not shed particles or out-gas volatile chemicals that may contaminate microarray slides. The 5 Slide Holder has a hinged lid that snaps closed tightly to prevent slides from accidentally falling out. The 25 Slide Holder has a lift off lid that is easy to open and close.
