model AT 38C in nutshell

Titration is one of the most established analytical technique and is still commonly used in laboratories across the wide variety of application fields. This wide range of applications are possible with Automatic Potentiometric Titrator when it is having high accuracy & reproducibility. It should also have flexibility, good scope to select right parameters for right applications. There has to be facility to choose the method itself, which can perform a given titration. The method development thus becomes a sure way to get the correct results with respect to concentration and tolerance limits. It is possible to store the developed method and recalled for that application. The system is user friendly and the data obtained is tamper proof, authentic; supported by statistics and software provisions to keep the result secured.

AT38C, meets and exceeds all these requirements, It has four basic methods, each method having several parameters which can be selected to make the method standardised optimally to get accurate results in shorter time. There are as many as 51 user methods which can be stored and recalled whenever required

AT38C, is provided with three-point auto calibration and standardization (Zero offset). The instrument is capable of displaying pH and mV of the sample, either compensated (when an external temperature sensor is connected) or non-compensated, enabling the user to use Titrator as a simple pH Meter. However this is only a side benefit, main purpose is to use it as a titrator. The automatic temperature compensation is essential during pH Cut-Off and pH-STAT Titrations.

The liquid path comprises of Teflon tubings, Three way ptfe valve and gas tight burette with Teflon piston. It creates chemically inert system for any sensitive analysis. 

The instrument is supplied with high speed vortex stirrer with speed controlling through on/off knob.This specially designed stirrer provides excellent homogeneous mixing of samples. An optional magnetic stirrer is also available.

AT38C, can accept a variety of electrodes to cater to various Applications in different fields.


METHODS

ASD 
Anticipatory Speed Dosing 
FED
Fixed End Point Dosing 
SVD
Step Volume Dosing 
PH STAT
For titration with variable dosing speed. Automatic slowdown as EP approaches. Suitable EP 
Criteria can be given
For titration with fixed 
mv or pH
For titration with Fixed Dosing steps. EP determined with jump in mv. Or pH suitable EP criteria can be given In PH - Stat method, 
the pH value is 
maintained until the 
pre set time interval 
is fulfilled

RESULT CALCULATIONS

* By last potential jump * By highest potential jump
* With selected potential jump * With potential jump in window of selected parameters. 

SECURITY & STATISTICS

* Reprocessing of data with security remarks.  * Statistics to give directly mean, standard deviations and Linearity. 
* Automatic incremented titration number to make the system foolproof
 

* Due to continuous R & D the specification & Dimensions are subject to Modifications
