A. COVER OF THE HEAD
The sampling head with its protective plastic lid can be autoclaved at 121°C for 15 min.
Alternatively, the sampling head can be sanitised by treating the inside and outside surfaces
with a disinfecting alcohol wipe or swab.
B. CONTACT PLATE HOUSING HEAD
The unit complete with the sampling head can be sanitised using a disinfecting aerosol (e.g.:
Isopropyl alcohol sterile spray cod. 18223) held at about 30 cm from the head when the fan is
running. 30 seconds are sufficient to disinfect the air path.
C. BODY OF THE UNIT
The plastic body of the unit can be wiped with a mild chemical agent.
Note.
The air sampler is a scientific instrument and its surface should be disinfected using an
aerosol and not a liquid!
4.11. “CONTACT PLATES” PREPARATION
It is important that the volume of media dispensed into a “Contact Plate” is constant for the
type of plate used. An excess volume can create a convex surface that is too high and which
may touch the inside of the sampler head. An insufficient volume will create a concave surface,
unsuitable for representative colony growth using SAS System.
The volume of agar in a “55 mm Contact Plate” should be 16-18 ml and in a ”84 mm Maxi-
Contact Plate” 24-26 ml.
