Smart and safe coverage

In order to prevent contamination during reactions and into the laboratory environment, DWK Life Sciences has developed a safety cover, the innovative DURAN® silicone lid range.

Five flexible sizes, three bright colours, versatile and simple to use!

The new way to cover vessels.

Versatile: The new DURAN® silicone lid is suitable for a wide range of applications as it can be used to cover and seal a variety of differently shaped lab containers.

Safe: The DURAN® silicone lid seals flush with the container and protects the contents from dust or splashes. With the help of the integrated pull tabs, the lid can be easily removed by hand or with gloves.

Identifiable: Three different colours (pink, cyan and green) make it easy to colour mark different samples. In addition, sample information can be written with a lab marker on the marking field  flap to indicate the sample.

Sustainable: The DURAN® silicone lids are reusable, easy to clean and dishwasher-safe. This results in less waste, and a lower environment impact.

Technical Product Information

The stretchy DURAN® silicone lids are resistant to both chemicals and heat. They are recommended for use at temperatures between -40 and +180 °C.

The DURAN® lids are manufactured from silicone, which is an autoclavable, and microwave-safe material. However due to the pressure changes that occur during autoclaving the lids may become loose, or tear, as a result they are not recommended for this type of application.

Note: Please note that prolonged exposure to a solvent will cause swelling of the material. Product applications with direct solvent contact must be tested and evaluated by the user prior to the start of the test. Furthermore, the relevant health and safety regulations must be observed.
