Details

Duran® 21 805 series reagent bottles

Wide mouth, round shape, with polypropylene screw cap and clear pouring ring (except 25ml size) which ensures smooth transfer of contents without drips. Also with plastic coating to protect against mechanical damage. The coating remains transparent after repeated autoclaving up to 135°C and is UV absorbent to 380nm. This allows use in a similar way to amber bottles. The bottle, cap and pouring ring can be used up to 140°C. With approximate graduations.

The properties of Duran® are specified in ISO 3585. Contrasting with other borosilicate 3.3 glasses, Duran® is particularly known for its highly consistent, technically reproducible quality.

General specifications:
The maximum permissible operating temperature is 500 °C. Above 525 °C the glass begins to soften and then above 860°C it changes to the liquid state. Duran® can be cooled down to the maximum possible negative temperature and is therefore suitable for use with liquid nitrogen (at aproximately – 196°C). In general Duran® products are recommended for use down to – 70 °C. During thawing, please ensure that the temperature difference does not exceed 100 K. Duran® glassware is characterised by high resistance to changes in temperature (ΔT=100 K). With its very low coefficient of linear expansion (3.3 x 10–6 K–1), literally no stress builds up within the article when rapid temperature changes occur.

This optimum physical and chemical performance ensures that Duran® is the ideal material for use in the laboratory.

Further technical details are available on request.

                       Important Warning - Sterilising Bottles
  Some bottles where indicated can be sterilised by autoclaving. However BEFORE AUTOCLAVING 
  (or sterilising by gas or dry heat) the cap or closure must either be removed or just set on top of the 
  container  WITHOUT ENGAGING THE THREAD.
