Scharlau, The wise choice
Culture Media for Microbiology
Dehydrated and prepared culture media: Introduction
Prepared culture media
90mm Petri dishes
Tubes with solid media
Manufactured in clean room under laminar flow class
ISO 5 (Class 100). The standard presentation is in units
of 10 wrapped plates up to a total of 20 plates per box.
Also available irradiated and with double wrapping.
Shelf life: 3 months.
Tubes with agar to be re-melted without loss of
nutritional capacity or changes in pH. The content
of each tube is enough to fill a Petri dish of 90mm,
which makes this product suitable for mass inoculation.
They come with a metallic cap suitable for
microwave re-melting. Each vial contains 15mL and is
available in boxes of 20 units. Shelf life: 12 months.
Also available in boxes of 20 tubes: double concentrated media, slanted agar media, etc.
55mm filtration plates
55mm plates prepared with a solid medium, to be used
in the membrane filtration technique. Commonly used in
the study of the pollution of water and liquids in general.
Manufactured in clean room under laminar flow class ISO
5 (Class 100). These plates come in a blister pack of
6 plates each. This way plates can be individually compartmentalized.
Each box comes packed with 5 blisters
making a total of 30 plates. Finally, each blister comes wrapped in a cellophane bag.
Shelf life: 6 months.
Contact plates
Plates for control tests on surfaces. Manufactured in a
clean room under laminar flow class ISO 5 (Class 100).
These plates come in a blister pack of 6 plates each.
In this way each plate can be individually compartmentalized.
Each box contains a total of 5 blister packs with
a total of 30 plates. Finally each blister pack comes
wrapped in a cellophane bag. Double or triple packaging
is possible. Shelf life: 6 months (All plates in this presentation are irradiated as
long as the nature of the media allows so).
Agars in flasks
Broths in flasks
Agars in flasks to be re-melted with no loss of nutritional
capacity or changes in pH. Available in volumes of
100mL and 200mL in boxes of 10 units. Removable
label for easy data transfer. Shelf life: 12 months.
Broths in flasks are subjected to a process of filtration
before bottling and sterilization, to obtain very clear
media. The media destined for the control of sterility
carry a cap with septum. Available in volumes of 90,
100, 200 and 225mL in boxes of 10 units. Transparent
label for better observation of the results.
Shelf life: 12 months.
Scharlau also publishes a “Handbook of Microbiological
Culture Media”. Please ask for your copy or download
product specific data sheets from our website.
Tubes with liquid media
Tubes which contain media and have a metallic cap
with a special seal that guarantees the sterility and
stability of the product. Our filling system guarantees
a minimal deviation of the amount to be filled, which
is very important to obtain accurate and reproducible
results when working with the MPN (Most Probable
Number) technique or in routine dilutions. Available
in volumes of 20, 5, 10 and 19mL in boxes of 20 units. Shelf life: 12 months.
Broths and diluents in bags (FlexiBags)
This is a packaging designed for laboratories in microbiological food control with a
large number of samples. Its most outstanding advantages are:
- Product is ready for use - Cost efficient
- Safe - Generates less waste
Dosage: The desired volume of sterile medium is dispensed by means of commercially
available gravimetric dilutors.
Connection: By means of a reusable stainless steel needle which is connected aseptically
to the bag through a septum. Available in 3 sizes: 2 litres, 3 litres and 5 litres.
Shelf life: 9 months.
Storage of prepared media
90mm plates should be stored at a temperature range of 4-14°C (this means that
refrigeration can be a storage option). Alternatively plates can also be stored at a
range of 2-25°C, whilst still maintaining proper performance of the medium. However
some precautions must be taken:
- In a range of 2-4°C, freezing must be avoided.
- In a range of 15-25°C, dehydration must be monitored.
For other products we recommend storage at room temperature, with no need for
refrigeration. Our products are manufactured following a production system that
guarantees maximum quality and stability of the product throughout its shelf life. To
ensure this a number of strict processes and controls are implemented:
- Rigorous control of sterilization temperatures.
- Precision weighing of the ingredients and of the media.
- Homogeneity of lots due to a strictly monitored manufacturing system.
- Excellent recovery of test organisms.
- Packaging specially designed to maintain optimal moisture conditions throughout
the life of the product.
- Maintenance of the physical and chemical characteristics of the medium: pH,
colour, moisture, etc., throughout it’s life.
