What are examples of laboratory glassware
Collection and packaging of the most common types of waste
If you cannot assign certain waste from your work area to any of the groups listed, please contact us. We are happy to help.
All contaminated solvents and solvent mixtures, also halogenated or containing water.
The pH value must be in the neutral range (pH 5-8), reactive components (peroxides) must be avoided in any case!
In 5 L disposable canisters (PE). These are available from the Hazardous Waste Disposal department.
It should be checked whether single-variety collection is possible. The Hazardous Waste Disposal Department provides collection containers if necessary and can take care of the distillative processing. Solvent recycling.
Must be collected separately, taking into account their toxic properties:
Very toxic waste in red plastic bags and noxious waste in transparent bags. Cannulas and other pointed or sharp-edged objects must also be packed in puncture-proof containers (e.g. screw-top containers).
Chemical-wetted filters, cellulose, gloves, contaminated small containers. No glass!
Spray cans do not belong in the equipment. They have to be submitted separately.
In transparent, strong plastic bags (available in our department).
Glass and ceramics
Destroyed reaction flasks and test tubes, evaporation dishes, other contaminated broken glass.
In yellow 10 liter buckets with lids. These are available from the Hazardous Waste Disposal department.
This type of waste only includes stubbornly contaminated glass. Glass bottles that can be washed without a lot of effort belong washed and without labels or hazard symbols in the waste glass containers of the municipal cleaning office. For the rest of the clean laboratory glass, collection containers are set up in the driveway.
Filter and absorbent masses
Contaminated, unreactive, inorganic salts such as chromatography residues, silica gel and desiccants (no Sicapent!)
If possible, no filter paper, the pH value of the dry matter must be in the neutral range (pH 6-8).
In white 10 liter buckets, tightly closed with a lid.
Old laboratory chemicals
Laboratory chemicals contaminated or used.
In special cases and after prior consultation, also "unknown" chemicals.
Chemicals that need to be kept refrigerated.
Please ensure that such chemicals are completely used up in your laboratories or that residual amounts are destroyed without damage. We would be happy to advise you on possible destruction reactions.
Individually, if possible in clean (original) containers.
Trivial names or laboratory abbreviations are not sufficient, ingredients are to be named explicitly. In the case of mixtures of substances, state the main and secondary components.
Inorganic acids and bases
Acids and alkalis are to be collected separately in 10 L disposable canisters. These are available in our department.
The use of chromosulfuric acid as a degreasing agent should be completely avoided. Less dangerous alternatives are available from chemical traders, e.g. "Extran", "Sidosil", "RBS 35".
Broken thermometer, old mercury from bubble counters, etc.
In tightly closed containers, e.g. PE wide-neck bottles.
Infectious Waste, Disinfected Waste and Body Parts, Blood and Organ Waste.
In tightly closed 30 L, 50 L or 60 L disposable containers. You can obtain empty containers from our department.
The containers must be clearly labeled and provided with a hazardous goods sticker (biohazard).
Mineral oil-based waste oils, for example from internal combustion engines or transmissions.
Chemically contaminated oils, for example from transformers or vacuum pumps.
e.g. in 10 L canisters (filling quantity max. 90%). These are available in our department.
Drilling and grinding emulsions
In canisters or 200 L drums
Please register with us before handing in so that we can order a collection container in good time.
We do not accept radioactive waste. Please contact the isotope laboratory of the Faculty of Biology. Dr. Thorsten Seidel, Tel .: 5588.
