To ISO 3819. 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.\u003c\/p\u003e\n\u003cp\u003eGeneral specifications:\u003cbr\u003eThe 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 approximately – 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\u003csup\u003e–6\u003c\/sup\u003e K\u003csup\u003e–1\u003c\/sup\u003e), literally no stress builds up within the article when rapid temperature changes occur.\u003c\/p\u003e\n\u003cp\u003eThis optimum physical and chemical performance ensures that Duran® is the ideal material for use in the laboratory.\u003c\/p\u003e","brand":"thelabwarehouse.com","offers":[{"title":"Default Title","offer_id":7658924113985,"sku":"BN163-55","price":21.53,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/8463\/8785\/products\/BN163_0e7c59d3-600d-4b2e-89db-72836b05578d.jpg?v=1599558466","url":"https:\/\/www.thelabwarehouse.com\/products\/beaker-duran-glass-tall-form-graduated-with-spout-800ml","provider":"thelabwarehouse.com","version":"1.0","type":"link"}
