Karl Fischer Titration









Specification :

The instrument is designed for accurate estimation of moisture in various Solid, Liquids or Gas samples. It works on Volumetric Principle.
The incorporation of latest microcontroller based circuitry ensures trouble-free performance with perfect reproducible results and total reliability.



The instrument is having a built in magnetic stirrer with speed controller. The Karl Fischer Reagent is added automatically to the reaction beaker by a highly sensitive motorized dispensing system. This dispensing system eliminates the need of Glass Burette, Piston Type Syringe, and Control Valves, thus greatly minimizing of hazardous and corrosive Karl Fischer Reagent. The dispensing makes the instrument very easy for day to day maintenance.

A feather touch keyboard enables the operator to enter data such as sample quantity, density and other data related to the test. A built in method is available for determination of titer factor.

The K/F Reagent added is volumetrically displayed on the digital readout with 0.01-ml readability. The moisture in the sample is calculated in terms of PPM or Percentage by the instrument automatically.

An audio alarm and suitable message indicate the end point of the titration. The alphanumeric display makes the instrument users friendly by prompting the instructions during course of titration.


A Printer Port, compatible with 80 column Dot Matrix EPSON printer, is available for printing the results of the sample under test.

Vertical Autoclave

nside chamber, outside chamber, fly screw, cross pin, flange and die pressed lid ar

Construction:
Inside chamber, outside chamber, fly screw, cross pin, flange and die pressed lid are fully stainless steel (304) All internal joints are argon welded.
Fittings:
Lid is fitted with pressure gauge, safety valve (set at 15 psi) , extra safety valve / fusible plug (set at approximately 20 psi) , manual exhaust valve and vacuum breaker. Drain valve at bottom. Model Neoprene gasket.
Electric:
Specially designed industrial grade energy efficient heaters which reduces the heater wattage and hence power bills by about 30%
Supply 240 V A C 50 HZ, single phase.
Standard accessories:
Heater cover stainless steel X Stand.
Digital Timer
Digital Temperature indicator cum preset controller
Miniature circuit breaker
Automatic purging
End cycle buzzer and auto shut off for a truly automatic operation, once it is set and started.
Process
Once the water is filled, the material loaded the timer set the lid tightened and power switched on the process is fully automatic to the end. Automatic purging (free steaming) taken care of by a solenoid valve. The preset temperature (121'deg C) is attained.
AFTER attaining the set temperature, the countdown of the timer starts. During this period the controller maintains the emperature (pressure) by switching off / on heaters, This saves precious energy and hence money. After the preset time, there is an audio alarm, the solenoid valve opened to exhaust the pressure, and the system switched off.

Manual Manifold

Gas manifold is used to connect two or more cylinders of same type with common cylinder regulator. The advantage of using manifold is to change from empty cylinder to filled cylinder without disconnecting the gas. MOC is brass chrome plated with ISI mark valve. It also consists of high pressure flexible pigtail of 1 meter long with " teflon tubing with SS brading with mounting bracket. The manifold are also available for two or more cylinders.

Gas Control Box

Gas distribution panel is used when there is more than one Gas Chromatograph. It helps to controlled the flow & pressure of different gases for different GC's. Gas distribution panels are available in three different types. One is with pressure gauge (to indicate pressure), pressure regulator (to control pressure), ON/OFF valve (to isolate). Second with pressure gauge and ON/OFF valve. Third is with only ON/OFF valve.
