Teaching
of Experimental Physiology and Pharmacology in India, which till
date decade was considered at per with advanced countries of the
world, had unfortunately lagged behind with the introduction of
Electronics Experimental techniques in the rest of the world,
including the developing countries. In India this aspect of
physiological experiments is still carried out with
Electro-Mechanical devices. These have inherent disadvantages in
the interpretation of sensitive recording, their lack of
capabilities for experiments in Human Physiology, and in the
proper evaluation of the action of drugs.
The two
basic factors responsible for inhibiting the adoption modern
systems in India are:
1.
Financial constraints, the existing electronics System
(like Polygraph) are too expensive for the extensive use in
Student’s lab.
2.
The system designs of Polygraph etc are rather
complicated for the student to understand and operate.
Keeping in
the view these two restraining factors, and to bring
Experimental Physiology and Pharmacology in India at par with
the rest of the world, BIO DEVICES have designed their STUDENT
PHYSIOGRAPH for the group experimentation by the student at
undergraduate and postgraduate level.
After sales back up of
STUDENT PHYSIOGRAPH:
An
equipment from Bio Devices come to you with the backing of
battery of the experienced, dedicated and devoted people, to
ensure that it remains functional, hassle-free and an asset for
you, for life.
With the
changing times and technology, system upgradation is a must in
order to be with the Physiograph. Thereby, ensuring that with
Student Physiograph, you always stay ahead.
Ease of Operation of STUDENT
PHYSIOGRAPH:
Even a
beginner can easily understand and operate the STUDENT
PHYSIOGRAPH with just simple explanation. Controls are kept to
be bare minimum, without sacrificing any function or
sensitivity.
Sensitivity has not been sacrificed in designing the STUDENT
PHYSIOGRAPH. Sensitivities as high as 5 micro volts per mm are
obtainable.
Ruggedness
is reliability, so essential for an instrument or system which
would be used by different batches of students. Versatility
through the use of couplers for recording of various parameters.
Concept of group experimentation
with STUDENT PHYSIOGRAPH:
Group
experimentation concept which permits more then one STUDENT
PHYSIOGRAPH to be used independently or interconnected to each
other for the same experiments set-up, or interchanged with each
other to record from different experiment set-ups in the
laboratory.
The
STUDENT PHYSIOGRAPH: is complete system design with couplers,
matching Transducers & Pick-ups, and matching Electronics
Stimulators with facility of synchronized event maker time
maker.
