Unit 2- Assignment 2- M3
Non-specialist laboratory
A non-specialist laboratory is made to be useful for several purposes, without focusing on one
specific area
...
Also, it must be easy for people to enter in and out the room, with
good air circulation
...

It should contain the basic furniture, such as tables which resistant to chemicals and heat to prevent
any damages and accidents that may occur
...
There must also be a fume cupboard to capture and
remove air-borne hazardous substances generated during laboratory experiments (e
...
gases,
vapours, aerosols and particulates/dust)
...
Some laboratories may also have a safety shower
...
A fume cupboard is typically a large piece of
equipment enclosing five sides of a work area, the bottom of which is most commonly located at a
standing work height
...
These are just a few
examples of what the water supply is needed for
...

Safety instructions - Safety instructions are also needed for a non-specialised laboratory; it contains
the information of what to do in the event of a fire, where the emergency exits are in the building, a
risk assessment, staff and student responsibilities, things that staff should check (e
...
electricity,
lighting, windows, etc
...

Gas supply - A gas supply is an essential component of a non-specialised laboratory, it is needed for
the Bunsen burners that are used in experiments
...
The gas is then ignited and burns constantly as long as the gas tap and switch is on
...

Fire blanket - A fire blanket is a safety device designed to extinguish small incipient fires
...

Fire extinguishers - A fire extinguisher is an active fire protection device used to extinguish or control
small fires, often in emergency situations
...
e
...
), or otherwise requires the expertise of a fire department
...
There are several types of fire extinguishers:
•
•

Water - For wood, paper, textiles and solid material fires
...


•
•

Carbon dioxide - For use on electrical fires
...


Eyewash - Eyewash is a fluid, commonly saline, used in the aid of rinsing of the eye
...

Storage space - Storage space is needed to store equipment, so that the laboratory is an efficient
place
...

First aid kit - A first aid kit is a collection of supplies and equipment for use in giving first aid and can
be put together, for the purpose by an individual or organization or purchased complete
...

Incubator - This maintains objects or substances at a particular temperature, often human body
temperature
...

Heating mantle - A source of heat when a naked flame could be dangerous
Burette - graduated glass tube with a tap at one end used to perform titrations
Desiccator - A vessel containing a substance that attracts moisture so keeping the contents drier
than in the open atmosphere
...

Centrifuge - This separates solids and liquids, particles of different sizes or liquids of different
densities
...

Balance - This measures the mass of objects
...

Oven - This heats substances, often to high temperatures
Test tubes - A test tube is a common piece of laboratory glassware consisting of a finger-like length
of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom
...

Lab coats - A laboratory coat is a knee-length overcoat worn by professionals involved in laboratory
work
...


Safety goggles - Goggles or safety glasses are forms of protective eyewear that usually enclose or
protect the area surrounding the eye in order to prevent particulates, water or chemicals from
striking the eyes
...

Bunsen burner - A Bunsen burner, is a common piece of laboratory equipment that produces a single
open gas flame, which is used for heating, sterilization, and combustion
...


Specialist laboratory
A specialist laboratory is made to be useful for only one purpose, focusing on one specific area (for
example, microbiology)
...
Also, it must be easy for people to enter in and out the room, with
good air circulation
...

Many labs include equipment designed to culture samples
...
It is also important to maintain a sealed container so the culture cannot escape
and possibly cause disease or contamination of other cultures
...
Samples are generally added to the
agar with the use of a wire loop or pipette, and warm water baths are needed to keep the culture at
a temperature for maximum growth
...

Microbiology lab must focus on trying to reduce the possibility of contamination of equipment,
samples, researchers and the lab surfaces
...
Autoclaves or pressure cookers are used to sterilize media, solutions
and equipment before and after use
...

Microscopes are a critical feature of a microbiology lab, as are the slides that must be prepared in
three possible ways: wet mount, simple smear and direct stain
...

Safety equipment such as lab coats, safety glasses, latex gloves, heat resistant mittens and other
protective gear are must-haves in any biology lab
...
You will also find a spill
station, equipped with disinfectant, disposable gloves, dustpan and brush, and paper towels or

cloth
...
Benchtops should be impervious to
water, heat resistant, and be able to withstand common chemicals such as organic solvents, acids
and disinfectants
...

A laboratory coat is a knee-length overcoat worn by professionals involved in laboratory work
...

Safety goggles - Goggles or safety glasses are forms of protective eyewear that usually enclose or
protect the area surrounding the eye in order to prevent particulates, water or chemicals from
striking the eyes
...

Heat resistant mittens -These are used to protect the hands against heat from hot objects
...

Safety shower - A safety shower is a device designed to wash chemicals off a person in the event of a
chemical spill
...

Electron microscope - The electron microscope is a type of microscope that uses a beam of electrons
to create an image of the specimen
...
They
are large, expensive pieces of equipment, generally standing alone in a small, specially designed
room and requiring trained personnel to operate them
...

Spectroscope - A tool that gathers molecular information about samples by passing by different
wavelengths of electromagnetic radiation (visible and invisible light) through the sample and
analysing the light that passes through
...
The gas can be
natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a
mixture of both
...

Agar - Agar is a jelly-like substance
...

Glass spreader - Designed for smooth-surface inoculation of media plates
...

Water bath - A water bath is used in the laboratory to allow a chemical reaction to occur at an
elevated temperature
...

Test tube holder - This is used to store the test tubes in so that they can stand upright without losing
their contents
...
A fume cupboard is typically a large piece of
equipment enclosing five sides of a work area, the bottom of which is most commonly located at a
standing work height
...
These are just a few
examples of what the water supply is needed for
...

...

Incubator - This maintains objects or substances at a particular temperature, often human body
temperature
...
The laboratory ensures that errors are minimised as much as possible
...
This would minimise parallax error significantly
...
The storage spaces are near and easy to access when you need to carry out an
experiment
...
The glassware is
also cleaned and sterilised thoughrally after carrying out an experiment, this is so that for the next
experiment, there would be no contaminants that would affect the results
...
They are put into yellow bags to identify the hazardous equipment
...
Radioactive, toxic and flammable substances are also disposed
of appropriately to prevent any risks
...
These are followed by carrying out risk assessments before carrying out experiments
...
In a risk assessment we
identify the hazards, risks and the action needed to take before to ensure that the risks are
minimised
...
The equipment is set up correctly and cautiously to prevent any accidents, for example,

keeping glassware and liquids away from the edge of the table
...
This is to ensure that we can minimise the chance of
an injury occurring
...
This is done by having a number of security guards at every entry of the
laboratory
...
The
storage spaces are locked to stop them from entering
...
The tables and equipment are
evenly spaced out so that it is easy for people to walk around
...
The sinks are within reach so that the health and
safety requirements are followed
...
