"Spectralab" Model PP-100 is microprocessor based Karl Fischer Titrator. It uses stepper motor driven peristalitic pump for delivery of KF reagent.

Salient Features:
KF delivery by stepper Motor driven Peristalitic Pump Due to the Stepper Motor precise dosing is achieved. As the pump mechanism is simple, maintenance is minimum. The only part which needs attention / replacement is small portion of tubing.

• Microprocessor based design
With this design no of descrete components are very few. Failure rate is thus reduced to as good as zero. The powerful microprocessor gives all the facilities which are available only in expensive Models.

• Compact Construction
Since very few components are used size is reduced & hence very little bench space is required

• Alphanumeric Soft Touch Membrane Key board
Again this is one feature which is available only in expensive models. You can enter sample details & can got result report in all the details like date, time, titration no, etc which are usually available in advanced models only.

• User friendly, Accurate & yet economical

• Inspite of the Advanced specifications, aesthetic looks, good accuracy, user friendly, display messages & all the above excellent features it is economically priced.

Air from the work environment is taken at a selected flow rate and allowed to pass through suitable sampling device where the pollutants are collected and lateron analysed in the lab with appropriate analytical technique.

For ease & convenience, the Handy Sampler is constructed with all the required items mounted in a compact case. It is fitted with Pump, timer Rotameter with Flow Controller & provision for holding Sampling Devices. Operates on Rechargeable Sealed Maintenance free Lead Acid Battery. The Battery Charger is built in.

Personal Sampler
Measurement of concentration of the pollutants in the work environment can be made by monitoring in the Employees Respiratory Zone, or better still by fixing portable sampling unit to the employee’s clothing. This is called Personal Sampling.

We offer following models :
PMP-3B - For General Sampling
LFP-2 - For Low Volatile Solvents & Aerosoles

These are miniature Thermoelectric Solid State Cooling/Heating Systems designed on the principle of "Peltier Effect". In laboratory analysis, need of analysis at arises. The lab chemist has to use either an elaborate and bulky compressor based cooling sysytem or use ice. Both these options have their own disadvantages. These Systems fulfill the needs of analysis at sub ambient temperature.

These systems are simple, sturdy & occupy very small bench space & cause no noise or vibrations. Since they are all Solid State designs, they are maintenance free.

These systems are suitable for Cold Tests, to carry out Titration at sub ambient or at elevated temperatures, to maintain Cell Holder Temperature , viscosity measurement, to cool vials & test tubes etc.

Spectralab offers variety of precision water baths as well as linear motion shaker fitted in the precision water bath for varied applications. The material of construction of inner tank is SS and outer body is MS powder coated. Level Control float switch along with solenoid valve for tap water intake ensures that certain water level is always maintained. Specially designed heater ensures uniform heating within ± 0.20 .

This pH meter is built on a state of art computer aided manufacturing facility using surface mount technology (SMT). The design uses high quality components with strict QC check that gives the instruments for many years without any trouble.

16 Character,Dual Line,back lighted LCD display. Settable stirring speed from 100 to 800 RPM through keyboard. Programmable count down timer for stirring. Stirring volume upto 1 liter 6 points or upto 200 ml 15 points. FRP Housing. Stirring points 6 Nos. for 1 liter or 15 Nos for 200 ml.
Typical Applications :
The facility to read rotation speed and count down time is extremely useful in standardising the condition of dissolving a sample. You can optimise and standardise a particular speed of rotation, time of stirring for a given weight of sample and volume of solvent, thereby ensuring complete and through disolution of sample before analysis.

Ultrasonic Cleaners transform low frequency AC current into high frequency sound waves via pizo electric transducers. Whenever high intensity ultrasound is applied to a solution, which in turn causes cavitation and the formation and violent collapse of minute vaccum bubbles in the solution. In a very short time, it removes the entire dirt from all components, which are immersed in the cleaning solution. Ultrasonic Clearing Bath is specially used for precious cleaning of small parts that contain contamination in some hard to reach comers.

These units are available with Orbital Shaking motion. These are ideal for slow as well as high speed shaking. These have variable speed control from 40 - 200 rpm. Ideally accepts 12 conical flasks of 250 ml or 8 conical flasks of 500 ml or 6 conical flasks of 1000 ml. Accessories for specific applications are available on request.
