JASCO unique rectangular cell with superior usability
Novel sampling cell was developed based on the customer feedback and needs.
(US patent: US D925,381, Europe patent: DM/205719, UK patent: GB 82057190001000, China patent: ZL201930223409.3)
Efficient pouring and flushing
RQC cells are designed for easy, bubble-free sample pouring and thorough flushing.
Superior temperature control
RQC cells quickly reach the set temperature due to the large contact area between cell jacket and cell.
Small-volume sampling
Minimum sample volume of 3 mm RQC cell with 100 mm optical pathlength is approx. 1 mL.

RQC-453 Rectangular quartz cell (3 mm × 3 mm × 100 mm)

RQC cell jacket
Plenty cell lineup
Each sampling cell is used with the dedicated cell jacket.

Dedicated accessories for P-4000 Series
SHP-403 Peltier sipper
SHP-403 allows sample loading from the front nozzle, followed by measurement and flushing. It saves time and effort in mounting and dismounting the cell.

TSR-411 Thermostatted plate
TSR-411 can preheat the sampling cell before the measurement, reducing the overall measurement time, including the heating after cell placement.

QPA-412/413/414/415
Practical standard quartz control plate
QPA is used for calibrating the instrument. JASCO also offers the quartz control plate with calibration certificate compliant with ISO/IEC 17025 compliance.

Optical filter
Optical filters must be changed according to the measurement wavelength. P-4300 has the automatic filter changer as standard.
