COM-1700 potentiometric titrator
The COM-1700 potentiometric titrator allows users to carry out up to four different types of titrations — including potentiometric, photometric, polarization, and conductometric titrations — in parallel. Its buret design allows for the quick, automatic exchange of reagents. The standard buret size is 20 mL, and optional buret sizes of 1, 5, 10, and 50 mL are available. Each titration station can control up to 10 burets. The new sample changer accommodates a wide selection of test tubes, beakers, and conical flasks. A color touch-screen panel allows for easy monitoring of any station and provides for real-time pH calibration and stability. Data can be printed from the unit or exported to laptops or PCs in several file formats.

Aquacounter AQL-2320 automated oil-evaporator Karl Fischer titration system
The Aquacounter AQL-2320 automated oil-evaporator Karl Fischer titration system is designed for analyzing moisture in difficult samples, such as oil, grease, paint, resins, bonding agents, etc. Using an azeotropic distillation solvent such as toluene or xylene, moisture can be evaporated at a lower temperature, which saves on expensive Karl Fischer reagents and lowers maintenance costs, since the titration cell remains clean and free of contaminants. The system heats samples up to 200°C and easily automates the addition of the azeotropic solvent. The sample tray can hold 20 samples and the operator can automate the exchange of Karl Fischer reagents.

AQUACOUNTER Karl Fischer volumetric titrator (AQV-2100S)
The AQUACOUNTER Karl Fischer volumetric titrator (AQV-2100S) has a wide detection range from 100 ppm to 100%. Its large color LCD screen displays all information relevant to each process, such as a real-time titration curve. Its automatic background-compensation function allows accurate volumetric measurements of trace moisture levels. The instrument can also be converted to either a two-channel volumetric-volumetric titrator or a two-channel volumetric-coulometric titrator. The volumetric conversion allows the use of titrants having two different strengths for maximum analytical flexibility.

AQUACOUNTER
The AQUACOUNTER coulometric Karl Fischer titrator (AQ-300) has six built-in calculation modes to accommodate solid, liquid and gas samples. It contains a statistics software package with one-touch calculations, and memory for four files with preset conditions that allow instant recall of up to 20 data samples. Its built-in detector monitors titration status. Users can choose either an ion exchange or a fritless cell system, as well as an optional thermal printer or impact printer. The unit has an inter-national voltage input (100–240 V). Printouts contain date, sample number, measurement value, sample quantity, moisture content, mean value, standard deviation, moisture quantity-time curve, and other preset titration parameters. Results may be printed or downloaded to a personal computer (PC).

AquaCounter EV-2000L oil evaporator
 The AquaCounter EV-2000L oil evaporator utilizes azeotropic distillation and completely separates water from sample matrices, thus eliminating any side reactions with interfering substances. The unit is especially useful for determining moisture in difficult samples such as heavy oils, grease, peanut butter, etc. The EV-2000L’s heating range is from ambient temperature to 200°C. Carrier gas is N2 gas or dry air and flow is 30–300 mL/min with inlet pressure at 0.8 MPa or less. The dessicant used is a molecular sieve and the unit has an aluminum block heater. Sample volume is approximately 10 mL or less. Height and weight is 220 (W) × 340 (D) × 265 (H) mm and about 7 kg. A wide variety of sampling devices are also available.
