Condenser
A condenser is a piece of equipment or machinery that can be used to condense, i.e. to shift the physical
state of a material from its gaseous state to its liquid state; it is usually used in laboratory procedures for
liquids brought into gaseous state by heating or vacuum application (low pressure); often a combination
of water or other substances.

Microspatula
For labs, microspatulas are small utensils made of stainless steel, used to grind, move or apply powders
and paste like chemicals or treatments. Most types of spatula are also resistant to acids, bases, heat and
solvents making them ideal for use with a wide variety of compounds. A common type would be
spatulas made of stainless steel, commonly used because they are resistant to deterioration from
contact with boiling water, acids, bases, and most solvents.

Retort
A retort is a tool used for distilling or dry distillation of substances in a chemistry lab. This consists of a
circular tube, with a long neck pointing downwards. The fluid to be distilled is poured in and heated in
the tank. The neck serves as a condenser, causing the vapors to condense and float down the neck to a
pipe beneath.

Stirring rod with rubber policeman
Rubber policeman attached to glass rod facilitates scraping and mixing when performing
gravimetric analysis. It can also be use in cleaning the sides of the insides of the glasswares by
scraping without scratching the vessel. They are chemically resistant, inert, and non-abrasive.
Avoid mixing too fast as it can shatter the vessel.

Serological pipette
This is used to transfer liquids measure in mL and can be used in mixing and/or layering
reagents. It is used in performing in the Urinalysis, Immunology, Hematology, Blood
Banking section of the laboratory. After treatment or isolation of experimental cell
cultures, serological pipettes are useful in transferring colonies of cells for further
empirical analysis or expansion.

Burettes
Burette is a long glass tube with volume markings and a stopcock at the bottom to start and stop
liquid flow. It delivers volumes of liquids useful in titrations. A standard size laboratory burette
can deliver up to 50.00 milliliters (mL) of liquid. In storing the burette, arrows pointing to the
holes into which one "ear" of the stopcock valve is placed. Placing the buret in the cabinet this
way assures that the buret will not fall out when the cabinet is opened.

Amber Reagent Bottles
Bottles typically come in two colors: clear and amber. Clear bottles are ideal for displaying items
and amber bottles protect the contents from light. Sizes range from 30 ml up to 20000 ml and
the larger ones may be used to store preserved biological specimens in the lab. It stores
photosensitive chemicals from direct sunlight or exposure to light. Very strong alkali should not
be stored in these bottles because the alkali can cause the stopper to corrode and fuse to the
neck of the bottle. Also, hydrofluoric acid should never be stored in glass containers because it
will actually dissolve the glass.

Iron Clamp
It is used to hold on to laboratory vessels and elevate whatever the clamp is holding so they
don’t fall apart and to support a ring stand. Clamp holders may secure the laboratory
equipment, as needed, at specific angles, diameters and weights. Some clamp holders are
used to secure the attached tool over a work surface. There are several different types of
holders that require adjustments to different angles and planes, such as swivel holders and
all-position holders. It can be used in some situations to fasten support rods together.
