"The VERSA Spotter has enabled our lab to construct our own microarrays. Thanks to the microarray printer, we now are easily construct microarrays to analyze glycan-protein interactions which is a significant resource to our lab in particular."
Automated Microarray Spotter
Swift, Accurate and Efficient Microarray Printer for Peptides, DNA and Cells
Aurora’s SPOT synthesis technique, using cellulose supports and liquid handling technology, led to the development of the VERSA series microarray printer (microarrayer). With expertise in life science robotics, Aurora addressed the growing demand for automated solutions in peptide synthesis and microarrays. The VERSA microarray spotter, with the nano-pipettor head, enables precise contact or non-contact spotting, supporting grams to milligrams of combinatorial chemistry.

Can VERSA Automated Microarray Spotter be used for contact and/or non-contact spotting? And what type of array surfaces can be used?
VERSA automated spotter is available as either contact/non-contact printing. VERSA is capable of dispensing sub-microliter volumes onto diverse substrates in a variety of patterns. It is compatible with different microarray printing surfaces including slides, membranes, micro-well plates, papers and biosensor substrates.
What is the VERSA spotting size/volume? And optimal distance between the individual spots?
The Spotting volume for contact printing is 40nL-300μL and for non-contact printing 100nL and more. The distance between each spot can be as small as 100μm (center to center).
What type of specimen can by arrayed by VERSA microarray spotter?
All biological samples including DNA, RNA, protein and cells or cell lysates can be arrayed by VERSA Automated Microarray Spotter. VERSA microarrayer is also capable of sequential layering of spots and can be customized for your specific needs.
Does VERSA spotter have washing station?
Yes, the VERSA microarray spotter is equipped with one flushing station and one washing station. An optional sonicating wash station is available if required by your protocol.
What is the number of channels on pipetting head for microdispensing?
Our standard VERSA microarray spotter comes with a single-channel NanoPipettor with one (1) single-channel stainless steel probe for contact printing and Single channel NanoPipettor with optional 1-2 channel ReagentDrop for non-contact printing. It can also be multichannel such as 4 channel or 8 channel or even we can customize it as 35 channel or 96 channel pipette head.
