Metrohm^® 711 Liquino^®

Innovative dosing and universal liquid handling

The 711 Liquino is revolutionizing dispensing and dilution due to its precision, easy-to-use interface and practical features. Speed and accuracy in a small space are very much in demand, and the 711 Liquino fits all of these criteria. Whether in analytical or synthesis laboratories, or in process chemistry, the 711 Liquino fills a wide variety of applications, including temperature-controlled dosing in chemical synthesis to fully automated sampling for titration, and offers a wide range of possibilities for use.

Dispensing and dilution
Designed with a small footprint, the 711 Liquino controls up to four bottletop 700 Dosino^® dispensing systems, each of which can be controlled independently, either manually or with internally stored methods.

A daily task of every analytical lab is standard preparation. Whether for voltammetry, ICP, AA, ion chromatography, photometry or spectroscopy, the 711 Liquino makes the work considerably easier and accurate with its automated method for the preparation of standard solutions. Preparation of a standard solution gravimetrically can be done by entering the exact mass of the standard substance that has been weighed in or even connecting a balance directly to the Liquino. For volumetric standards, a large variety of methods can be created and stored for recall and use at any time.

With its dispensing capabilities as wide-ranging and varying as the technique itself, the 711 Liquino PIP and SEQ modes make even the most complex dispensing process as easy as pushing a button. The 700 Dosino is an integrated part of the new standard in bottletop liquid handling.

With unprecedented accuracy and precision applied to a typically manual process, the 711 Liquino brings a level of confidence to all users for basic and advanced liquid handling.

Analysis and synthesis
The 711 Liquino can be used for a wide variety of applications including automated sampling, timed dispensing and temperature-controlled synthesis. The 711 has an RS-232C interface, which allows the connection of a balance or a printer for direct transfer of sample information and for printer output. This option also allows the Liquino to be remotely controlled from your computer for more integration. The external “Remote” line on the instrument allows you to control a titrator, a sample changer or other instruments, as well as an easy-to-use pipetting tip.

A Pt 100 temperature sensor input and a PTFE thermometer (Pt 100) that is suitable for syntheses is available as an accessory. This option makes the Liquino an ideal solution for applications such as diazotization reactions or nitrations, in which defined temperatures must be maintained. You can enter upper or lower temperature limits on the instrument with individual alarm functions. If limits are exceeded, pumps or baths, connected via the Remote line, can be employed.
