2.3 Performance Characteristics:
Gradient Forming:
Tilt Angle: 0-90° in 0.1° increments.
Rotate speed: 0-60RPM
Fractionation:
Piston Speed: 0.1-6.5 mm/sec down, 6.5 mm/sec upward
Fraction Size: 0.01 mm - full tube length
Number of Fractions: 1-99 in each of 10 sections per gradient
Band Illumination System: 20W halogen spot with dichroic reflector
Rinse Capability (programmable in any order, up to 9 events between each fraction):
•Continuous air to section outflow with air bubbles during fractionation
•Air on demand or automatically between fractions: 15 msec to 9 sec
•Water/Buffer on demand or automatically: 15 msec to 9 sec
•Delay (a programmed interval between fractions): 15 msec to 9 sec
•Pause (an indefinite pause between fractions, broken by pressing START)
•Fraction Advance (a contact closure that signals a connected fraction
collector to advance one fraction): 15 msec to 9 sec pulse
User Memories: 20. Each memory performs automatic fractionation of a specific
gradient and contains up to 10 different segments with each segment
containing user entered values of piston speed, distance per fraction,
number of fractions and rinse.
Macro Record: The device will reproduce a manual run if it is recorded using this
feature. The memory becomes one of the 20 memories listed above and can
be edited and saved.
