Sample changer for piston burettes and automatic titrators

The number of samples to be processed is growing constantly while at the same time the demands on reliability are increasing in accordance with GLP and ISO 900X standards. The TW alpha plus changers help you meet these increased requirements and relieve qualified employees from routine work.

The control of the sample changer is carried out via the software TitriSoft.

The following properties characterize the TW alpha plus:

• Stirring from below is possible with the built-in magnetic stirrer or from above with an optional rod stirrer (Propeller stirrer)

• The titration heads and sample trays are easy and quick to change
• The size of the sample tray is set via the PC software.
• The usable sample vessels have a volume of 50 - 600 ml
• For rinsing the electrodes and titration tips, a rinsing pump (only 12- and 16-position sample trays) and/or up-to three rinsing positions can be used.
• The calibration of a pH electrode can also be done on the sample changer.

The sample tray with 24 positions is suitable for 50 ml beakers tall form and plastic beakers. The 50 ml beakers are typical for total acidity titration in wine, juices, and other beverages.
