Automatic Analysis
Sipper Unit
The following accessories are used to continuously supply samples to a sample compartment for measurement. The sipper unit automatically supplies sample solutions to cells using a stepping motor-driven peristaltic pump. When this unit and the auto-sample chamber are used together, up to 100 samples can be measured automatically and continuously.
- For UVmini,UV-1280/1800/1900series/2600series/2700series/3600/3600Plus series
*) This unit cannot be used for strong acids, strong alkalis or ester solutions since the tubes of the stepping motor-driven peristaltic pump are not chemical-resistant. Buy the separate solenoid valve unit (fluorine resin treated) and SWA-2 sample waste unit
Syringe Sipper N/CN
Two types of syringe sippers are available: the normal-temperature type (N) and the constant-temperature water-circulation type (CN). The sipper unit uses a syringe pump system. Liquid-contact surfaces are made of fluorine resin, glass or fused silica, which means that they are very resistant to chemicals and easy to maintain, allowing measurement of almost any type of sample. They also feature an extremely high sipping volume repeatability (repeat precision: &plusmin;0.03 mL). The flow cell is available separately. Choose from the recommended flow cells in the table below.
- For UVmini,UV-1280/1800/1900series/2600series/2700series/3600/3600Plus series
*) When used on the UVmini series, the sample compartment unit is required. Also, on the UVmini series, the square flow-thru (super-micro) cell with 2 mm dia. light-thru section cannot be used.
| Recommended Flow Cells | |||
|---|---|---|---|
| Type | Optical Path Length | Aperture Dimensions | Standard Required Sample Volume |
| Square flow cell (super-micro) | 10 mm | φ 2mm | 0.9 mL |
| Square flow cell (micro) | 10 mm | φ 3mm | 1.0 mL |
| Square flow cell (semi-micro) | 10 mm | 11 mm H × 3.5 mm W | 5.0 mL |
ASC-5
Use this accessory with a sipper unit or syringe sipper to configure an automated multi-sample spectrophotometry system.
- For UVmini,UV-1280/1800/1900series/2600series/2700series/3600/3600Plus series
*) A commercially available test tube stand with a 220 ´ 220 mm or smaller footprint can be used.
*) When used on the UV-1800, the ASC USB adapter is required.
SWA-2 Sample Waste Unit
This handy unit is used instead of an aspirator.
- For UVmini,UV-1280/1800/1900series/2600series/2700series/3600/3600Plus series
*) When an aspirator is used, use of this unit is recommended since fluctuation in the water pressure causes the sample suction volume to fluctuate.
