Replicator Stamp with 12 Cloths
The technique with the replica stamp is used to identify and isolate auxo-
trophic mutants from a bacterial strain. To do so, bacteria or yeast colonies
are moved from one agar plate to another. Using the following method, fix
a sterile cloth to the stamp with the holding ring and then press the top
side of the colony plate to the stamp lightly. A duplicate is then produced
using a fresh agar plate. Our replicator stamp is suitable for standard Petri
dishes up to 10 cm. You can sterilize the stamp and holding ring with Etha-
nol. The cloths, made of a cotton polyester mix can be autoclaved.

Drigalski Spatula
This stainless-steel Drigalski spatula is widely used in micro-biological
work. It is used to achieve an even spread of single cell and cell-cluster
microorganisms on an agar plate. Our Drigalski spatula is available in two
designs, both of which are 19 cm in length and made of stainless steel:
Drigalski spatula, straight head

Bacteriology Starter Kit
Microbiology is very important in everyday life, so it is exciting for
pupils to learn about it through experimentation. Our bacteriol
ogy starter kit contains the basic equipment you will need
to carry out microbiology experiments with your pu-
pils in upper secondary school. These user instruc-
tions describe general microbiology work methods,
and explain how to carry out a range of microbiology
experiments:
• Testing for bacteria and carrying out a bacterial
count in soil
• Testing for bacteria and carrying out a bacterial count in
water
• Testing for air-borne bacteria
• Microscopy of bacteria
• Determination of generation times at different tempera-
tures
• Effectiveness of antibiotics
• Occurrence of natural mutations and their characterisation
The experiments are designed for 4 groups of pupils and can be
easily incorporated into everyday school life.
Scope of delivery:
