1. Solid Evaporator EV-2000

The EV-2000 is designed for solid samples which are not soluble in the Karl Fischer reagent or contains interfering substances. EV-2000 works with our AQUACOUNTER Karl Fischer titrator series and can be automatically controlled from the AQ-2100 or AQV-2100 titrator.

	EV-2000 Standard Specifications
	Heating Temperature Room temperature to 350 Carrier gas N2 gas or dry air Carrier gas flow rate 0.1 - 0.5 L/min Carrier gas input pressure 0.8MPa or less Carrier gas desiccant Molecular sieves Heater Aluminium block heater Sample volume About 10mL or less Power supply, Power consumption AC100V - 240V, 50/60Hz, 150VA Dimensions, Weight 220 (W) x 430 (D) x 200 (H) mm, about 8kg

2. Oil Evaporator EV-2000L

The EV-2000L Oil Evaporator utilizes azeotropic distillation (Micro Dean & Stark Distillation). It completely separates water from sample matrices, thus eliminating any side reactions with interfering substances. The EV-2000L can be used with AQUACOUNTER Karl Fischer titrators, or any other manufacturer's titrators.

	EV-2000L Standard Specifications
	Evaporation method Azeotropic distillation method Heating range Room temperature to 200 Carrier gas N2 gas or dry air Carrier gas flow rate 30 - 300mL/min Carrier gas inlet pressure 0.8 MPa or less Carrier gas desiccant Molecular Sieves Heater, Heating block material Aluminium block heater Sample volume About 10ml or less Measurement range The same as that of the connected titrator. Azeotropic Solvent Benzene, toluene, Xylene, etc. Volume for one measurement; 5-10mL. Power supply, Power consumption 100 V - 240 V, AC 50/60 Hz, 150 VA. Dimensions, Weight 220 (W) x340 (D) x 265 (H) mm, about 7kg

3. Automated Solid Evaporator EV-2010

The EV-2010 automated evaporator/sample changer can be connected with both AQ-2100 coulometric titrator and AQV-2100 volumetric titrator, which makes the AQS-2110 a complete, automated evaporation KF titration system.

	For medium to heavy workloads Up to 10 samples can be placed on the turntable at the same time. Up to 99 samples can be run by simply removing the finished sample and adding a new one. Extremely compact design A compact upright design for both the heating block and the KF titrator saves valuable bench space. Wide temperature range and programmable temperature control The heating temperature can be set up to 300 and programmed up to 3 steps. This feature makes it easier to find the optimum temperature for each individual sample, or allows you to differentiate surface water from bound water. Dry Air Pump (Optional) Compact, integrated air pump eliminates the need for nitrogen carrier gas.
	EV-2010 Standard Specifications
	ITEM SPECIFICATIONS Number of sample vials 10 Volume of sample vial 10mL Seal PTFE cap with aluminium foil Carrier gas Nitrogen or Dry air (Optional) Carrier gas flow rate 30 - 300mL/min Carrier gas desiccant Molecular Sieves Heater, Heating block material Aluminium block heater Heating range Room temperature to 300 Power supply, Power consumption 100 - 240V, AC 50/60Hz, 250VA Dimensions, Weight 260 (W) x 600 (D) x 280 (H) mm, about 11kg

4. AQL-2120 Automatic Oil Evaporator

	Click here to View Slideshow	Based on azeotropic distillation method, moisture is separated from sample matrices and other interfering substances. Sample changer holds up to 20 vials. Exchanging the KF reagent can also be automated (Option). Wide temperature setting (RT- 200 C) covers the full range of azeotropic points. Reduces costs for KF reagent and waste disposal.
