HD-CQ4
Introduction：
Automatic Liquid-Liquid Extractor uses air pressure to fully combine the water sample and extractant for automatic extraction, degassing and cleaning. Widely used for environmental, food and pharmaceutical lab extraction....
The HD-CQ4 automatic liquid-liquid extraction (LLE) instrument consists of an extraction flask, a gas-liquid pump and a control unit. Its working principle is to use air pressure to fully combine the water sample and extractant with violent collision for complete extraction. It completely replaces manual shaking, reduces the operator's labor intensity and avoids direct contact with toxic reagents, protecting the operator's health. The whole extraction process requires no manual venting and can extract automatically, greatly reducing environmental pollution and improving extraction efficiency.
Suitable for water petroleum and other cases requiring liquid-liquid extraction in water-quality monitoring; also for automatic LLE of volatile phenol and anionic surfactants in water.
HJ 637-2018 – Water quality – Determination of petroleum and animal/vegetable oils – Infrared spectrophotometry
HJ 970-2018 – Water quality – Determination of petroleum – Ultraviolet spectrophotometry
GB 7494-87 – Determination of anionic surfactants
HJ 503-2009 – Water quality – Determination of volatile phenol – 4-aminoantipyrine spectrophotometry
Four-position independent design; each glass unit can be used independently without mutual interference.
Four independent timers, each usable independently.
Each extraction flask has an independent PTFE air tube inserted to the bottom for extraction.
Semi-closed air-flow oscillation via a built-in air pump; extraction power is adjustable from weak to strong via a knob.
Waste gas generated during reaction is auto-vented with no manual venting, avoiding the burst risk of fully closed flasks.
Avoids direct contact between the operator and toxic extractants.
Capacity: 1000 ml × 4; 500 ml × 4 (optional).
Timer: 0 – 99 h.
Voltage: 220 V, 50 Hz.
