Liquid Handling Systems

Overview

At the heart of all CAT liquid handling instruments there is a rotary-axial piston and cylinder, machined from an acid-proof ceramic, Al2O3 which is extremely hard and highly chemical resistant, ensuring a long working life. The motorized units are driven by a robust stepper-motor, powered via a 12 volt AC adaptor.
The great advantage of this new developement is its valveless construction, benefiting in minimum dead volume and removing the normal tendency to jam or leak. The units are also self-deaireating, which guarantees that measurement errors caused by air bubbles are avoided. Since the fluid pathways are either PTFE or Al2O3, the system can be thoroughly cleansed and chemically sterillised.


Contiburette µ10H - Manual burette

Rotating the handwheel enables the Contiburette to deliver liquid with an accuracy of <=0.1%. The volume is displayed by LCD, with a resolution of 10µl.Now with user calibration.

Prices from 532.00 exc VAT and Delivery


Contiburette µ10D - Motorized burette

This version of Contiburette may be operated either by 3 built-in function switches or by a choice of optionable remote controllers. The built-in functions allow a continuous run mode, a 10µl dispense and to zero the LCD. The stepper-motor dispenses 3ml of media in less than 10 seconds with a constant accuracy of <=0.1% (EV). Now with user calibration and RS485 interface.

Contiburette µ1D - Motorized burette

This version of Contiburette may be operated either by 3 built-in function switches or by a choice of optionable remote controllers. The built-in functions allow a continuous run mode, a 1µl dispense and to zero the LCD. The stepper-motor dispenses 3ml of media in less than 10 seconds with a constant accuracy of <=0.1% (EV). Now with user calibration and RS485 interface.

Liquid-processor

Liquid-processor is a high-precision, bottle mounted liquid-handling system able to dispense by volume, weight and timed flow-rate, in a number of different modes, in volumes of 10l up to 100litres.

With its ceramic system, it is especially suited to dispensing aggressive fluids and its advantage is that it does not require the liquid to be decanted into a reservoir first. The remote key-pad and optional hand-set allows use in hazardous areas and the mounting arrangement contains harmful vapours from aggressive media.

The user selects the required function and values, e.g. volume and flow rate, such as l, ml, mg, g, l/s, ml/m., via the key-pad or PC through the RS232. A Windows program is available for this task.

Liquid-processor is extremely versatile - applications include precise dosing of a set volume, manual dispensing, time-controlled dispensing, diluting and titrating .

A combined Analogue and digital I/O port allows for connection to your own hardware controller, allowing the system to be switched on at a pre-programmed flow-rate or a program step to be performed. An analogue output also provides a readout of the actual flow rate for data logging purposes.

Liquid-processor is also now available coupled with a pH controller providing a simple, low-cost titration unit.
