IIGel purification systemTechnical parameters:

1) P15 high-pressure preparation pump

Flow range: 0.001ml/min~10ml/min

Flow accuracy: ≤ 0.5%

Flow stability: RSD<0.1%

Pressure range: 0.00MPa~42MPa (420Kgf/cm2)

Imported motor, imported driver, segmented into 20000 steps, no mechanical noise; Ensure accuracy.

Imported sealing system with strong high pressure resistance.

Imported high-efficiency pulsation damper with strong buffering capacity to minimize pulsation.

Display mode: LCD screen display.

Display mode: actual pressure, flow rate setting, pressure upper and lower limit setting.

Safety control: pressure upper and lower limit control, buzzer alarm, automatic shutdown.

2) UV15 variable wavelength ultraviolet detector

Optical system: Imported design diffraction grating monochromator, imported photoelectric receiving device.

Light source: Hamamatsu L6302 deuterium lamp from Japan

Wavelength range: 190-700nm

Wavelength accuracy: ± 1nm

Wavelength repeatability: ± 0.5nm

Noise: 2.5 × 10-5AU (p-p) (dynamic index, mobile phase methanol, 254nm, column connection)

Drift: 1 × 10-3AU/hr (dynamic index, mobile phase methanol, 254nm, column attached)

Attenuation range: 0.002-2AU/mL, V10 level

Detection pool volume: 4.5 μ l;

Small detectable amount: 2 × 10-8g/ml (naphthalene/methanol solution)

LCD screen display, electrically controlled wavelength finding, electrically controlled zero adjustment, simple and easy to learn.

*The deuterium lamp is controlled by a starting voltage, which allows the deuterium lamp to have a lifespan of up to 2500 hours.

The design of the counter pressure device makes it difficult for bubbles to enter the circulation pool.

3) Workstation

It has batch processing function and can perform batch table editing, insertion, deletion, saving, pause and other functions. Data collection, data calibration, data processing and reporting, data output to Word or Excel for further processing.
