SPECIFICATIONS
Performance
- Printing Method: Contact printing. Proprietary head and printing pins
are available. The system can accommodate heads from other vendors.
- Number of printing needles: 1-48 in various patterns with 4x4, 4x8 or 4x12 LabNEXT printing head. The control software can work with any printing pattern in case of using printing heads of other vendors.
- Needles spacing: 4.5 mm, 9 mm for 384 and 96 well plates correspondingly.
- Slides capacity: two configurations of 30 or 45 slides. Any number of them can be used for pre-spotting.
- Source plates capacity: two configurations 3 or 6 plates.
-
Labware compatibility: 96, 384, 1536 plates
- Slide locks: independent. The system can accommodate from 1 to 45 slides in any positions.
- Needles cleaning technology: fluid stream washing, vacuum drying.
- Print layouts: multiple identical microarrays at a slide. Pick-up and spotting repetitions.
- Throughput: 2 min per print cycle (Print cycle: Wash, Dry, Pick-up,
Pre-spot, Deposit at 13 slides). 384 well plate can be printed in 7-8 min with
48 pins
- Environmental Control: on-board
electronic humidifier. Maintains
relative humidity inside the system cabinet in the range of 40-80% with 2%
precision.
Mechanical
- Accessible operating area: L 376mm, W 382mm, H 70mm
- Resolution: X, Y - 0.002 mm, Z - 0.005 mm (spacing between two nearest possible spots)
- Absolute accuracy: X, Y - 0.05 mm, Z - 0.05 mm. (accuracy of positioning the most remote from the origin spots within the work area)
- Repeatability within the same run: X, Y - 0.01 mm, Z - 0.01 mm (accuracy of returning to the same spot without run interruption.)
- Repeatability after run interruption: X, Y - 0.01 mm, Z - 0.01 mm (accuracy of returning to the same spot after the system has been stopped and re-initialized)
Environmental
