TECHNICAL SPECIFICATION
Fraction collector & auto samplers LAMBDA OMNICOLL
| Type | LAMBDA OMNICOLL – microprocessor-controlled programmable fraction collector – sampler |
| Collection mode | Linear (line), meander (zigzag) or row collection |
| Normal modus | |
| Time | 0.1 to 999.9 minutes (16.67 hours) in 0.1 min steps or 1 to 9999 minutes (166.7 hours) in 1 min steps |
| Volume | 0.01 to 500 ml or 0.6 to 30 litres (external counts using LAMBDA peristaltic pump) |
| High modus | same as Normal modus, but with a pause between fractions (from 0.1 to 999.9 minutes or 1 to 9999 minutes) |
| Remote control | |
| Normal modus | Collector takes a single fraction after an external voltage pulse of 3-12 V (or 12-30 V with a 3300 ohm resistor) |
| High modus | Collector takes a 1 to 999 fractions after a single external voltage pulse of 3-12 V (or 12-30 V with a 3300 ohm resistor) |
| Capacity | Any tube rack or container type with a surface smaller than 45 x 31cm |
| Standard racks supplied | 360 tubes of 12-13 mm diameter 240 tubes of 16 mm diameter 160 tubes of 20 mm diameter 96 tubes of 30 mm diameter |
| The capacity can be increased many times by coupling several lower fraction collector parts together. | |
| Non-volatile memory | storage of all settings |
| Interface | RS-232 (optional) |
| Power supply | 95–240 V/60–50 Hz AC plug-in power supply with DC 9V/12W output; possible field operation on 12 V accumulator |
| Dimensions | 34 (W) x 30 (H) x 49 (D) cm |
| Weight | 6.5 Kg |
| Safety | CE, meets IEC 1010/1 norm for laboratory instruments |
| Operation temperature | 0-40 °C |
| Operation humidity | 0-90% RH, not condensing |
| Remote control | 0-10 V; (option 0-20 or 4-20 mA) |
| Fuse | 1.5 A (on printed circuit board) |
| Guarantee | 2 years |
For safety reasons, the voltage of the external signal must not exceed 48V to earth!
