Automatic Analysis

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

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.
