Description
Specifications:
Flow rate:
- 1.3 – 1.7 LPM with Millipak® Express 20
- 1.3 – 1.7 LPM with BioPak
Resistivity:
- Minimum 18.0 MΩ.cm @ 25°C
- Typically 18.2 MΩ.cm @ 25°C
Particles: ≤ 1/ml (particle size >, 0.22 μm)
Pyrogens: BioPak installed <, 0.001 Eu/ml
TOC: Maximum 5 ppb (this specification came from test conditions where a Milli-Q Gradient was fitted with a Q-Gard® 1 Purification Pack and a Quantum EX Ultrapure Cartridge and the feedwater came from a Millipore RiOs Water System. The feedwater TOC value was <, 50 ppb). The TOC of the Milli-Q Product Water can vary as a function of the feedwater TOC.
Micro-Organisms: ≤ 1 CFU/ml
Weight:
Milli-Q Gradient: Operating weight (wetted Q-Gard, Quantum and Millipak): 16 kg.
- Milli-Q Gradient A10: Operating weight: 16.8 kg.
Electrical:
The electrical requirements for a Milli-Q Gradient (or Milli-Q Gradient A10) are:
- 120 VAC ± 10%, 50/60 Hz, 100 VA, 0.5 amp source, 2 amp Time Lag fuse used (ref. ZMQS6V0T1, MQP6V0T1, ZMQS6V001, ZMQP6V001).
- 230 VAC ± 10%, 50/60 Hz. 0.26 amp source, 1 amp Time Lag fuse used (ref. ZMQS5V0T1, ZMQP5V0T1, ZMQS5V001, ZMQP5V001).
- The source of electrical power should be within 1 meter of the Milli-Q. The source of electrical power must be earth grounded.
Measurement Ranges for TOC, Resistivity, Conductivity and Temperature:
- Resistivity Measurement Range: 2.4 – 18.2 MΩ.cm (compensated to a 25°C value)
- Conductivity Measurement Range: 0.055 – 0.294 μS/cm
- Temperature Measurement Range: 0 – 45°C (not the system temperature operating range)
- TOC Measurement Range: 1 – 999 ppb
