We provide ultrasonic Bath Sonicator with the principal of ultrasonic cleaner. It is a high frequency electrical energy that is converted into ultrasound waves by means of ultrasonic transducers, which are bonded on the base of S.S. water tank. The ultrasonic bath sonicator are high frequency sound waves that are created in the liquid countless, microscopic vacuum bubbles, which rapidly expand & collapse. This phenomenon is cavitation. The bubbles act like miniature high speed brushes, driving the liquid into all openings and minutes recesses of the object immersed in the liquid. Excessive scrubbing of cavitation cleans away all the dirt and soil from the object immersed and the object is effectively cleaned. An intricate object can also be completely cleaned or by little dismanting.Salient Features Easy to operate & made of one piece S.S. tank Indigenously manufactured with advanced MOSFET technology, with Auto-tuning facility.

The main unit of this apparatus incorporates the Microprocessor Based circuitry. A light feather touch key board is fitted on the side of an informative alpha numeric display. The display indicates the emf in millivolts generated during the titration process and also the millivolts generated with each addition of volume of titrant to the reaction beaker and the total volume of titrant added. The time interval between two consecutive additions of the titrant is also shown on the display. All the factors such as the volume of titrant to be added in each addition, the time interval between two consecutive additions and the total volume of titrant to be added can be pre-set in the program with the key board. The cabinet of the main unit itself serves as a sturdy titration stand with built-in magnetic stirrer. It holds the titration beaker with electrodes and inlet for titrant. A motorized precision dispensing unit housed in a small box can be kept on the main cabinet and connected on the side of the titration beaker making the equipment quite compact.A highly precision metering dispenser correctly follows the commands from the microprocessor based circuitry in the main unit and accurately adds preset volumes of the titrant at pre-set intervals as per the set program. Observing the parameters on the alpha numeric display such as the Volume of titrant added with each additions, time interval between consecutive additions, emf in millivolts being generated during the titration process and particularly that generated with each addition of fixed volume of titrant, one can easily draw the graph with clear indication of peak values. If necessary, a printer can be interfaced to print all these parameters to preserve a record.

A microscope is an instrument to see objects too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope.There are many types of microscopes, the most common and first to be invented is the optical microscope which uses light to image the sample 

The instrument is designed to determine the Melting Point of solids or Boiling Points of liquids, with high accuracy .The apparatus incorporates the latest type of MICROPROCESSOR BASED circuitry and is very simple to operate. The apparatus consists of a cylindrical Silicon Oil bath with heater. A sample is filled in a capillary and suspended through the Teflon cover of the Silicon Oil bath. Similarly a Boiling Point tube with sample liquid can also be suspended through the Teflon cover to determine Boiling Point of a liquid sample. Temperature of the bath is maintained uniform with built -in magnetic stirrer. The unit is equipped with colour video camera , which magnifies the image of the capillary with sample, so that minute physical changes can be observed on the colour monitor with ease. The apparatus is equipped with four lines alphanumeric informative LCD Screen which indicates PRODUCT NAME, BATCH No. SET TEMP.ACTUAL TEMP.START OF MELTING POINT etc…The self-explanatory feather touch keyboard enables to set the desired program for heating the Silicon Oil bath .The unit is provided with socket to accept universal centronics parallel printer interface. Any 80 column dot matrix printer is connected will print the header, product name ,batch no. ,date and time of the test ,and rise in temp./min towards last 10 C. It also prints START OF MELTING POINT. An audio signal draws the attention of the operator for close observation of the Melting Point towards the final reading. The Melting Point can be clearly observed on the monitor. If through oversight one fails to stop heating, after reaching Melting Point, it stops automatically with TEST OVER message, when the temperature reaches 10 C, above the set temperature of the program. The range of the Melting Point can also be observed The instrument is also having the facility for testing unknown sample. When UNKNOWN SAMPLE key is pressed the temperature will start rising at nominal rate so that it is easy to observe where the Melting Point.The instrument supports the validation method by using difference standard samples such as VANILINE, BENZOIC ACID & CAFFINE.The range of the instrument is 40 C to 300 CReadability 0.1 C, with accuracy 0.1% .The unit works on 230volts/50Hz, A. C. mains supply.

Gas manifold is used to connect two or more cylinders of same type with common cylinder regulator.
