Programmable automated washer for Ria coated tubes and beads. Thirty programs can be entered and permanently stored. Each program can combine buffer delivery, several aspiration modes ( fast, accurate and for beads ) and waiting time instructions: It performs them in cycles eventually to be repeated on the same column or on all the columns to be washed. The manifold and the tray are designed to wash 60-tube racks (12 X 5 rows). The number of rows to be washed can be selected. On request washers can be adapted to custom racks.

Main specifications:

• Pumps: Membrane air-pump 16 l/min.
• Washing methods: Aspirate method 1) rapid and direct from the bottom - 2) fast selectable level and slow down to the bottom level of aspiration.
• Dispensing volume Variable and programmable (>100 µl < 2,9ml) Even when an amount of liquid grater than the well's capacity is dispensed, no overflow effect occurs since the aspirating tips are always operating.
• Dispense level: selctable in 9 steps
• Tube rack: 5 X 12 columns
• Capacity: 2 racks
• System: Programmable
• Control: Keyboard multifunction with LCD display
• Washing Head : 12 couples of tips for aspirating and dispensing on a single column.
• Software 30 programs that can be memorized. In each protocol aspirating instructions (in different modes) dispensing instructions (from 100 µl to 2,9 ml), waiting time (0- 99" with or without the starting access of the operator at the expirating time), can be organized in cycles on each strip and on the whole plate. It is possible to link different protocols.
• Dispensing accuracy ± 5%
• Residual volume: after washing: <3 µl on tubes.<10 µl on beads.
• Electric requirements: 220 V or 110 Dimension cm 41 X 34 X 24
• Weight (14 + 7) KG
