Solar distillation plant its Automated Solar water distillation plant for first stage distillation of water. A solar still is a simple way of distilling water, using the heat of the sun to drive evaporation of water to water vapors from still, and ambient air to cool water vapor. The pure water vapors condense on the cool inside glassplastic surface and drips down from the weighted low point, where it is collected and removed. The basic principles of solar water distillation are simple yet effective, as distillation replicates the way nature makes rain. The sun's energy heats water to the point ofevaporation. As the water evaporates, water vapor rises, condensing on the glass surface for collection. This process removes impurities such as salts and heavy metals as well as eliminates microbiological organisms. The end result is water cleaner than the purest rainwater.

The Digital Water Plethysmometer is designed to provide a highly useful tool in the measurement of small volume changes. The digital Plethysmometer is a micro controlled volume meter which is specially designed for accurate measurement of the rats and mice paw swelling.

In comparison with other digital Plethysmometer, we use advance imaging technology. By using camera

and software we directly calculate paw volume.

• Water loss correction provision for each reading
• Any normal water can be used for experiment
• No need of surfactant
• Image based technology
• Foot switch (USB foot switch)
• Computer software
• Accuracy 0.05 ml
• 35mm tube diameter for rats & mice(Optional 25mm tube diameter also available)
• Elegant Acrylic glass tube holder
• 1 cc calibration probe

It is fully computerized system designed to study contextual fear conditioning in rats and mice. This apparatus has been successfully used in studies of the psychophysiology and the psychopharmacology of fear conditioning and for exploring the effects of analgesics and anxiolytics.

By utilizing auditory cues, light cues and shock grid subject can be forced into freezing defensive posture. Fear conditioning apparatus software provides the user with the ability to control the cue type, cue duration and scoring frequency. The camera fitted on the top of the box records the start and end of freezing episodes. Freeze monitor software accurately reports total number of freezing episodes and total time freezing for each session. Contextual fear conditioning can be studied by using different vertical and horizontal strip textures onclear wall of fear conditioning apparatus.

• Simple user interface.
• With the help of fear conditioning software you can increase the efficiency and the perfection of your research, while reducing chance of human error.
• Video camera precisely records start and end of the freezing episodes.
• Configure up to two station
• By changing greed we can use it for rat and mice.

Hot and cold plate meter basically used for testing the analgesic reaction on rat and mice. Hot cold plates provide exceptional fast ramp rates that can be advantageous in labs and production. The VJs Hot and cold plate meter is based on a metal plate which can be heated to 65C and cooled to 1C (with an ambient temperature between 18C and 25C). An electronic thermostat maintains the plate's temperature and a front panel digital thermometer displays the current plate temperature. The animal's pain sensitivity resulting from exposure to heat or cold is tested by placing the animal on the surface of the plate and starting a built-in timer. The operator stops the timer at the instant the animal lifts its paw from the plate, reacting to the discomfort. The front panel timer then displays the number of seconds the animal took to react. Animal reaction time is a measurement of animal resistance to pain and is used to measure efficacy of analgesics.

• Simple user interface
• Design for both rat and mice
• Digital temperature set point
• Built in timer
• Foot switch timer operation
• Easy to clean
• Temperature accuracy 0.50C
• Uniform temperature on the plate

Kymograph, consisting of a revolving drum, bearing a record sheet on which a stylus moved up and down displaying the effects of the drugs on contractile tissues, was commonly used in experimental physiology and pharmacology laboratories in teaching institutions.

The heated rodent operating table is a sturdy piece of equipment that will stand up to daily use. The entire top portion of the table is mounted on four legs made of stainless steel. The standalone table has a warming chamber under the table top and contains a small, metal-sheathed heater. An energy regulator controls the table top surface varying the heating cycle when necessary. The regulator is controlled through digital temperature controller & uniform heat distribution is maintained over the entire surface.
The Homoeothermic Rodent Operating Table includes a rigid rectal thermometer-sensing probe and a sensitive control unit. The system continuously monitors the animals core temperature during surgery and, through the controller, automatically adjusts the table temperature.
We also provide HD microscopic camera which is fitted on the table top. Vertical and horizontal camera holding assembly helps you to adjust the camera as per your need. This camera is connected to the side screen on which we can watch the magnified view of the operation area. We can also connect this system to projector to have the magnifying view on the screen.

• Standalone unit
• Heated operating table and non-heated operating table
• Digital temperature controller (accuracy 0.1 deg.)
• Rectal probe
• Easy to handle
• Easy to clean
• HD microscopic camera
• Operation video recording facility(optional)

Water Maze is one of the most widely used methods to assess spatial and learning memory. The Water Maze tank is filled with water and equipped with a platform which acts as a means of escape for animals. During testing, animals learn the location of the platform using spatial cues.
The Morris Water Maze is a behavioral procedure designed to test special memory. The maze has advantages over conventional mazes such as:

• Elimination of local cues such as trace sents
• No fixed escape formula

Automatically calculated and analyze parameters related to learning and memory such as the time needed to find the hidden platform.
Analyzed behavior in relation to zones, such as the time spent in specific quadrant.

An isolated Tissue bath (Organ Bath) assay is the classical pharmacological screening tool to assess concentration-response relationships in contractile tissue. Although a variety of molecular tools have become available in recent decades to assess cellular responses in high-throughput quantities, the organ bath assay is still considered a valuable tool for lead optimization and for the elucidation of the mechanism of action. In addition, organ bath assays are widely used in preclinical safety studies.
