 These types of pipettes are frequently used by molecular
biologists.
 The most commonly used micropipettes tips are:
Large blue – 200-1000μL
Small yellow – 2-200μL
Small white - ‹2μL
MORTAR AND PESTLE

 The pestle is a heavy club-shaped object, the end of which is
used for crushing and grinding.
 They are frequently associated in the profession of pharmacy.

3. A Cannula is a tube that can be inserted into a vein, an artery, or another body
cavity, often for the delivery or removal of fluid or for the gathering of data.

5. FORCEPS
Forceps are a handheld, hinged instrument used for grasping and holding objects. Forceps are
used when fingers are too large to grasp small objects or when many objects need to be held
at one time while the hands are used to perform a task.

22, 26, 28, 32, etc.
SURGICAL SUTURES AND NEEDLES
• Needle and thread combination comprising of non-absorbable black
nylon polyamide thread and stainless steel needle.
• The nylon is suitable for closing ophthalmic, neurological and
microvascular wounds.

8. ANAESTHETIC CHAMBER
• These are made of glass or plastic chambers available with various sizes for
giving anaesthesia to animals.
• The anaesthesia may be given by putting the animal inside the chamber along
with a cotton wetted with chloroform for a particular period of time.
HEATING MANTLE
• It is used to apply heat to containers in order to boil the contents.
• It can also be as an alternative to other forms of heated bath.
• It prevents shattering of glass containers as the mantle is insulated with proper
material.

9. MICROSCOPE
• A microscope is an instrument used to view the objects that are not visible
through naked eye.
• There are different types of microscopes such as:
Compound microscope, Scanning electron microscope, Ultra microscope, etc.
STUDENT ELECTRIC KYMOGRAPH
• Electrically driven recording drums suitable for use by students for general
experiments
• Drive mechanism consists of constant speed electric motor
• Various gear ratios are available and which are effected by sliding the lever
into the slot marked with surface speed

10. ISOLATED ORGAN BATH
• Bath chambers made out of thick transparent acrylic sheets or fibre glass and
they are welded to make leak proof.
• Temperature is achieved by placing a thermostatically controlled warming coil
inside the chamber.
• A suitable motor with propeller is suspended from top ensuring vibration
inside.
LEVERS
• These levers are used to record the contraction or relaxation of the isolated
tissue preparation.
• A sketch pen tip is cut and pointer is fixed to the lever. The levers which can be
used are simple, frontal writing and starling’s heart levers etc.

11. OPERATING TABLE
• It is made of Stainless Steel top and used for variety of applications.
• The table top is provided with drainage system, vertical adjustment through
latest pinion-lift system replacing hydraulic system.
ROTAROD APPARATUS
• The rota rod test is designed to evaluate the motor co-ordination activity in
laboratory animals.
• The rota rod is controlled by an advanced microprocessor which is provided
with timing control.
• Rotation can be set manually at a constant speed of 4-40 rpm
• Also acceleration rate may be selected at a defined time like 30 sec, 1, 2, 10,
30 min etc.

12. ELEVATED PLUSMAZE
• It is a rodent model of anxiety that is used as a screening test for anti-anxiety
agents.
• This plus shape apparatus consists of two open and enclosed arms elevated
40-70 cm from the floor.
• The model is based on rodent’s aversion of open spaces.
EDDY’S HOT PLATE
• The hot plate test is a test of the pain response in animals. It is almost
similar to tail flick test.
• The apparatus is used in testing the effectiveness of analgesics by reaction
to pain caused by heat.
• It’s a behavioural model of nociception where behaviours such as jumping
and hind paw licking are recorded.

13. POLE CLIMB APPARATUS
• It is a closed box with electrical rods inside and also designed with a pole
vertically at the centre.
• This apparatus also provided with electrical shocks of 400 v in pulsating
rates 0.2 mV of 5 sec frequency for 30 sec of duration.
ELECTRO CONVULSIOMETER
• This apparatus is commonly used in pharmacology experiments to screen
Anti-convulsant agents.
• The instrument provides about 50 Hz stimulus current which can be
adjusted from 0.15 mA to 330 mA in discrete steps for producing
seizures.

14. ACTOPHOTOMETER
• Most of the CNS acting drugs influence the locomotor activities in living organisms
and the locomotor activity can be an index of alertness of mental activity.
• It measures the spontaneous and indicated activity made by the animals during the
experimentation.
• The equipment also provided with electric shock of up to 100 volts for activating rats
or mice.

15. SCINTILLATION COUNTER
• A scintillation counter is an instrument for detecting and measuring ionizing
radiation.
• There are two main types of scintillator: Inorganic and Organic
• Four main components of scintillation counter are: A sheet of scintillator, A
light guide, A photomultiplier and the electronics in the p.m base.
pH METER
• A pH meter is an electronic device used for measuring the pH (acidity or
alkalinity) of a liquid.
• A typical pH meter consists of a special measuring probe connected to an
electronic meter that measures and displays the pH reading.

16. CENTRIFUGE
• A laboratory centrifuge is a piece of laboratory equipment
• It is an electrical instrument driven by a motor, which spins liquid samples at
high speed.
• There are various types of centrifuges, depending on the size and the sample
capacity.
• Eg: Micro centrifuge, Clinical centrifuge, etc.
BIOAMPLIFIER
• A Bioamplifier is an electrophysiological device
• It is used to gather and increase the signal integrity of physiologic electrical
activity for output to various sources.
• It may be an independent unit, or integrated into the electrodes.

17. SPECTROPHOTOMETER
• A spectrophotometer is employed to measure the amount of light that a
sample absorbs.
• It is usually employed in experimental pharmacology where the
estimations are being done.
ELECTROPHORESIS APPARATUS
• Gel electrophoresis is a method for separation and analysis of
macromolecules (DNA, RNA & Proteins) and their fragments, based
on their size and charge.
• It is used in clinical chemistry to separate proteins by charge and/or
size (IEF agarose, essentially size independent) and
in biochemistry and molecular biology to separate a mixed
population of DNA and RNA fragments by length, to estimate the size
of DNA and RNA fragments or to separate proteins by charge.

18. AUTO ANALYZER
• The Auto Analyser is an automated analyser using a flow technique called continuous flow
analysis (CFA).
• Auto Analysers were used mainly for routine repetitive medical laboratory analysis.
• The first industrial applications - mainly for water, soil extracts and fertilizer - used the same
hardware and techniques as clinical methods.
• Auto Analysers are still used for a few clinical applications such as neonatal screening.
