This is straight wire usually
circle of approximately 1.5mm and 3mm made up of platinum or nichrome wire with
handle which is use for picking colony from culture.
Nichrome wire is generally
adopted for making wire loop because it is cheaper, elastic and cool faster
compared to platinum wire. The wire loop must be renewing time to time. Now
there are commercially disposable plastic wire loop available in the market and
they are widely used in medical lab now are days. Wire can also be made in the
laboratory by the lab scientists, bellow are the procedure for making wire loop
in the laboratory;
| WIRE LOOP |
Cut wire approximately 10cm, and
must be platinum or nichrome wire.
Wind the wire once round a metal
rod of appropriate diameter.
With a pair scissors cut one aim
at the wire junction
Bend back the wire loop to centre
it
 |
| WIRE LOOP HANDLE |
Insert into a metal wire holder.
STERILIZATION OF WIRE LOOP
Hold the loop in the Bunsen flame in a vertical position
till red hot bring it out and allowed it to cool |
| WAY OF STERILIZING WIRE LOOP |
before using commence, and remember that you must sterilized your wire loop in each of colony you pick or in each of any sample you pick with it.
