Components of a Burette
COMPONENTS OF VOLUMETRIC BURETTE:
Volumetric or glass burette consists of a graduated glass tube with a
stopcock at one end. The precise liquid dispensed can be determined
by volume marking given on the glass tube surface. A Tip is given at the
other end of the glass burette which is used to dispense liquid precisely.
The Stopcock helps to control the flow of liquid by rotating it clockwise
or anti-clockwise.
COMPONENTS OF ELECTRONIC BURETTE:
E-Burette is an electronic device that delivers accurate and convenient
titration while reducing the risk of accidental chemical contact. It
includes some advanced components that reduce manual operation
with high work efficiency. Some major components of E-burette are:
Recirculation Valve:
a.
It prevents the loss of reagents during purging by re-directing them into
the mounted bottle.
Delivery Tube:
b.
Delivery tube provides the facility to deliver the reagent beyond the
reservoir.
Inspection Window:
c.
The transparent acrylic window can be replaced with an amber colored
window for the use of chemicals. These chemicals such as iodine,
potassium permanganate and silver nitrate solutions are sensitive and
can react in light. To protect these chemicals from such reactions, an
amber-colored window is used that can be easily changed.
Delivery nozzle:
d.
Delivery nozzle provides a high degree of flexibility in both the
horizontal and vertical directions, facilitating easy dispensing according
to different laboratory conditions.
