General Precautions
l
Chemicals can adversely affect the performance of
laboratory plasticware resulting in cracking, loss of strength and
flexibility etc.
l
If in any doubt, note the type of polymer the product is
manufactured from, the chemical that is to be used, then confirm
compatibility by checking against the chemical resistance chart.
(See pages 6-7).
Washing and cleaning
l
Most laboratory plasticware is readily cleaned in warm water
with a detergent and soft cloth or sponge.
l
Avoid using abrasive cleaners or scouring pads which can result
in surfaces becoming scratched.
l
A low or non-alkaline detergent is suitable for cleaning
most plasticware.
Note however that polystyrene and polycarbonate products
are susceptible to attack by alkalis and a neutral detergent is
recommended.
l
If using an automatic laboratory washing machine to wash
plastic volumetric ware, such as measuring cylinders, employ a
wash temperature below 60ºC. High temperatures can affect
volumetric accuracy.
l
Ultrasonic baths may be used for cleaning plasticware. However
do take care that the products do not directly touch the
transducer membrane.
Heating
l
Never place plasticware in direct contact with a flame or place
onto a hotplate surface.
l
Most plastics allow the transmission of microwaves.
However, as with any microwave vessel, be sure it holds a
microwave absorbing material, such as water, before placing in
the oven.
Sterilisation
l
If the plasticware is to be sterilised by autoclaving always
pre-check that the polymer can withstand repeated exposure to
temperatures of 121ºC.
l
Azlon
®
plastic products that are autoclavable are identified by
an
A
symbol in this catalogue.
l
When autoclaving bottles always ensure the caps are loosened
or removed to prevent accidental collapse or deformation.
Disposal
l
If the disposal of an item of plasticware is unavoidable, always
follow local laws and regulations.
Where reclamation facilities are offered it can be helpful to
segregate the products by polymer type: many Azlon
®
products
are marked with an SPI code to help identification.
Care and maintenance of laboratory plasticware
The following guidelines are provided to ensure your plastic laboratory-ware is maintained in the best possible condition.
These guidelines are not definitive and care must be taken as each polymer has its own unique properties. Please also consult the chemical
and physical properties charts in this catalogue. If you are still unsure please contact us for advice.
