0001-0220 - Systec AF Biotech DEGASi Prep+ Preparative Degasser, 2-channel, 100 ml/min per channel

Systec Biotech DEGASi Preparative Stand Alone Degasser, 2-Channel, Prep 20mL/min

• No. of Channels :- 2
• Volume Per Channel :- 8.4
• Max HPLC Gradient Flow CapabilityC (mL/min) :- 20
• Pressure DropD (kPa/mL/min) :- 0.04

The Systec Stand Alone Prep Scale vacuum degassing system for HPLC is a high  efficiency in line module that removes dissolved gasses from HPLC mobile phases.  Built for the rigors of modern preparative and semi-prep scale HPLC, its unique design  assures reliable continuous operation and the highest level of continuous performance  available. Two solvent lines may be degassed simultaneously by one unit.

Features

• Ultra-high degassing efficiency
• Low volume, easy to prime
• ZHCR® patented control eliminates baseline fluctuations
• Dual lumen design for low-flow resistance
• Inert flow path
• 5+ year lifetime
• CE & RoHS compliant
• 2-pin vacuum level validation output
• ZHCR® Control with Built-in Test Diagnostics
• Microcontroller self-test vacuum sensor validation on power-up
• Continuous vacuum system monitoring to ensure optimum operational conditions are maintained
• Vacuum system fault detection and shutdown function indicators
• Systec AF / ZHCR Degassing Technology

The prep / semi-prep scale degassing chambers are designed to be easy to prime, and are configured with a Systec AF degassing membrane to provide maximum degassing capacity with the absolute minimum internal volume (<3% of PTFE designs with comparable degassing capacity). The ZHCR (Zero Hysteresis / Constant Run) vacuum pump employs a patented closed-loop, micro-stepping RPM control strategy permitting the pump to run with continuously variable speed, providing quick pull-down at high RPM, and then sustaining a consistent vacuum level at low RPM. Fluctuations in detector baseline due to changes in vacuum level are eliminated by not having to repeatedly stop and start a single-speed pump. This also greatly reduces wear and noise. The brushless motor enables quiet operation and is appropriate for environments where solvent vapors may be present.

Validation Output
A 2-pin rear panel receptacle labeled “Validation” with mating screw-lock plug is provided to allow a validation signal from the control circuit to be sent to a computer or 
data system. This validation output indicates vacuum level. 

Signal: 
5mV DC / 0.13kPa (1 mmHg) absolute from 2.7 to 106.7 kPa (20 to 800 mmHg) (0.100V DC at 2.7 kPa (20 mmHg); 4.000V DC at 106.7 kPa (800 mmHg)

Accuracy: 
±1.0% of reading ±0.010V DC from 2.7 to 106.7 kPa (20 to 800 mmHg)

Power Requirement

• Input Power required with AC Adapter (included): 100 to 240V AC (±10%), 1A, 50 to 60 Hz (±3 Hz)
