The new automatic potentiometric titrator model COM-1700 series is upgraded and enhanced with the adaptation of a color touch panel screen, a USB flash memory port, a standard built-in thermal printer, a compact designed buret with easier use, extended lifetime and enhanced software. The COM-1700 series is by far the most advanced automatic titrator to be introduced and is the perfect choice for any and all automatic titration applications. The features and benefits of this titrator easily surpass all those that preceded it.
Advanced functions and excellent operational
performance - Built-in thermal printer with easy paper-loading features!
- Save & load titration parameters and result data on the USB flash memory!
- 7.5 inch Large color touch screen (LCD Protection film applied)
- Browse the data by PC on a LAN connection!
Easily control up to 4 independent multitasking
workstations. Sample Changer
A new compact design of the buret & the titration
station. | The new design reduces bench space
by 25% compared to the previous model. The new buret of the B-1700 is
compatible with conventional COM series titrators.
right: B-2000 (conventional type) |
New syringe - Conventional type Burette･reagent bottle･ buret-tip combination features and all-in-one snap change buret head for easy assembly and maintenance. |
The structure of the new syringe has a minimized dead volume for easy reagent exchange. (10mL, 20mL sizes)

POV (peroxide value) …is an important parameter used to determine the degradation level of oil and fat for quality control purposes. The POV is expressed as milligrams of iodine liberated from potassium iodide per kilogram of sample. The amount of iodide equal to peroxide contained in the sample is liberated based on the chemical formula (1)
Liberated iodide is titrated with 0.01mol/L sodium thi osulfate solution as formula (2).
| Reagents | Titrant: 0.01mol/L sodium thiosulfate solution |
| Titration solvent: acetic acid : isooctane = 3: 2 25mL for one measurement | |
| Additive: saturated potassium iodide solution | |
| Electrodes | Platinum-reference combination electrode PR-731B |
Points!
Since oil and fat tend to be easily oxidized atmospherically, it is important to constantly monitor the procedure. An additional POV kit will enhance the process of titration with nitrogen purge and the following steps can be smoothly and efficiently completed for accurate results.
