Arrayit offers pioneering Professional Series Technology for the most exacting microarray manufacturing applications. Our proprietary manufacturing approaches and materials provide ultra-high tolerances and extended durability for the finest ex situ printing performance specifications in the world. Contoured pin apertures (shown here) reduce printing friction by 66% and tighten printhead-pin clearance to 2.5 µm for superior durability and printing precision. Arrayit Professional technology is gaining increasing usage in leading core facilities, biotechnology and pharmaceutical companies, academic centers, government agencies, and diagnostic testing laboratories.

Figure 1. Arrayit Professonal Series Printhead 48 (Cat. PROPH48) with ultra high-precision contoured pin apertures for 66% reduced friction and 2.5 µm printhead-pin spacing for greater durability and printing precision.

Figure 2. Arrayit Professional Series Microarray Printing Pin. Shown is the pin point featuring a 75 µm wide tip (Cat. PRO3) and a 0.25 µl sample channel. Pro Series pins are constructed from Arrayit's proprietary RM101 alloy, which is 10- times more durable than stainless steel, ensuring 10 million printing cycles and faster printing speeds. Pin points are concentric to ±2.5 µm which allows perfect subgrid ("block") alignment and faster data analysis. Pro Technology represents a quantum advance over ChipMaker, Stealth and 946. The space bar (white) in the photograph corresponds to 500 µm (0.5 mm).For the most demanding microarray manufacturing applications.

Figure 3. Arrayit NanoPrint™ Professional Series Printhead (Cat. PRONPPH48). Printheads are manufactured to 1.25 µm tolerances for superior subgrid alignments yielding faster and more accurate microarray quantification. Our proprietary holders guide the pin shafts with 66% less friction than previous Printhead designs. Professional Printheads are available for the all Arrayit SpotBot® 2 and NanoPrint™ microarrayers, and other commercial systems.

Figure 4. Photograph of an ArrayIt® Brand Professional Series Microarray Printing Pin Tip. Shown is the pin tip in an "end on" view. The square 75 µm tip (Cat. PRO3) and the sample channel opening (center) are visible in the photograph. Pro Series pins are constructed from Arrayit's proprietary RM101 alloy, which is 10-times more durable than stainless steel, ensuring 10 million printing cycles and faster printing speeds. Pin tip dimensions and pin length are controlled to ±2.5 µm to ensure perfectly consist dwell time and spot size from pin to pin. Pro Technology represents a quantum advance over ChipMaker, Stealth and 946. The space bar (white) in the photograph corresponds to 50 µm (0.05 mm).
