Information for users

  • Products are generally handed out to persons who belong to an area listed in the respective material store, e.g. a working group. However, students from the practical courses need for reception a material slip signed by a responsible assistant.
  • A letter from the head of the requesting area stating the need for the material and the appropriate cost center is required to be submitted to Susanne Nitschke in order to obtain a receiving authorization, if one does not already exist.
  • Materials can only be provided subject to available storage quantities and capacity. In the case of larger or recurring quantities of a product, users are encouraged to purchase the product independently.
  • The delivery of materials to private persons is excluded.

The chemicals present in the material store can be viewed via the CLAKS system. The user group of the material administration is 392. A specific search for substances is possible via the "combination search" in CLAKS. 

  • Only canisters with liquid chemical waste that are filled to 90%, tightly closed, leak-proof overall, clean on the outside and correctly labeled are to be handed in! Canisters that do not comply with these criteria must unfortunately be rejected and transferred to other canisters in the laboratory.
  • Operating materials with chemical adhesions such as cellulose, filter papers, gloves, etc. are to be collected and handed in in 30 L snap lid buckets or appropriate waste bags.
  • Glass waste with chemical adhesions can be collected separately in 30L snap lid buckets and obtains its own label.
  • The buckets are to be closed tightly only before delivery still in the laboratory, since the lids are difficult to loosen again in the meantime. Do not overfill!
  • It is also important to ensure that the buckets are labeled correctly. Bags do not need to be labeled as they are disposed of in a large metal container (ASP) provided for this purpose.
  • Cannulas and glass are generally to be collected in puncture-proof containers, either with in the 30L operating material bucket respectivily glass waste bucket or smaller quantities in other small containers disposed of in the ASP for operating materials.
  • Empty waste containers (canisters, snap lid buckets) as well as labels are available free of charge on site during disposal hours. Waste bags are available in stock at the material store for laboratory materials.
  • In addition, information on handling a wide variety of waste is available from the Department of Sustainability and Energy.

The laboratories are responsible for the correct provision of laboratory waste with chemical components for disposal.

Information on the various collection points for toner cartridges, batteries, electrical and metal scrap can be obtained from the janitors of the respective locations, in Fabeckstr. 34/36 also from the material management in the building.
