Accessories
Film Holder
(P/N 204-58909) Used in transmittance measurement of thin samples such as films and filters. Holds thin samples, such as films and filters, for analysis.
Test Tube Holder
(P/N 207-23510-41) Holds test tube instead of sample compartment. Outside diameter: ø15 to 18 mm Height: 84 to 115 mm
Note: Test tube is not included.
Long-Path Rectangular Cell Holder
Holds two rectangular cells with an optical path length of 10, 20, 30, 50, 70, or 100 mm.
Multi-Cell Sample Compartment
(P/N 206-69160-41) Holds up to six 10-mm square cells on the sample side. No temperature control capability.
- Number of cells:6 on the sample side 1 on the reference side
Note: Square cells are not included, please purchase separately.
Sipper Unit
Four types of sipper units with different flow cells are available. The stepping motordriven peristaltic pump ensures reliable and smooth aspiration of sample solution. (Direct driving is possible from the UV-1900 so no interface is required.)
Note: The use of a Solenoid Valve (Fluoropolymer) (P/N 204-06599-01) and the SWA-2 Sample Waste Unit (206-23820-58) are recommended when strong acids, strong alkalis, or organic solvents are to be measured.
| Model | P/N | Standard Sample Volume |
| Sipper Unit 160L (Standard Sipper) | 206-23790-51 | 2.0mL |
| Sipper Unit 160T (Triple-Pass Sipper) | 206-23790-52 | 1.5mL |
| Sipper Unit 160C (Constant-Temperature Sipper) | 206-23790-53 | 2.5mL |
| Sipper Unit 160U (Supermicro Sipper) | 206-23790-54 | 0.5mL |
CPS-100 Cell Positioner, Thermoelectrically Temperature Controlled
(P/N 206-29500-**) This attachment permits measurement of up to six sample cells under constanttemperature conditions. Combination of this attachment and the Kinetics mode provides measurement of temperature-sensitive enzyme kinetics of one to six samples.
- Number of cells:6 on the sample side (temperature-controlled)
1 on the reference side (temperature not controlled)- Temperature control range: 16°C to 60°C
- Temperature display accuracy (difference from the true value): ± 0.5°C
- Temperature control precision (variation of temperature): ± 0.1°C
- Ambient temperature: 15°C to 35°C
Note: Square cells (P/N 200-34442) are not included, please purchase separately. A USB adapter CPS (P/N 206-25234-91) is required.
TCC-100 Thermoelectrically Temperature Controlled Cell Holder
(P/N 206-29510-**) Uses Peltier effect for controlling the sample and reference temperature, so no thermostated bath or cooling water is required.
- Number of cells: One each on the sample and reference sides (temperaturecontrolled)
- Temperature control range: 7°C to 60°C
- Temperature display accuracy (difference from the true value): ± 0.5°C
- Temperature control precision (variation of temperature): ± 0.1°C
Note: Square cells (P/N 200-34442) are not included, please purchase separately.
