Don’t let glassware contamination compromise your research

No matter how carefully you plan an experiment or how hard you and your team work, if your laboratory glassware is not cleaned effectively your research will suffer.

Even microscopic traces of foreign materials left on your equipment can cause errors in results, which could have an impact on your overall findings. Many laboratories go to great lengths to avoid the cross-contamination of samples but don’t put the same amount of thought into ensuring their glassware is cleaned effectively.

Some laboratory workers may prefer the traditional method of handwashing their glassware but this is likely to leave items covered in residual contaminants even if they appear clean to the human eye.

Common contaminants

Materials which are often found on laboratory glassware include:

  • Traces of chemicals used in previous experiments
  • Food particles including fat or protein left over from analysis of samples
  • Residue from detergent used to clean the equipment
  • Bacteria and microbes
  • Grease, especially if glassware has been handled without gloves

It is also important to clean any new laboratory glassware before it is used for the first time as unused glass is alkaline and must be treated with acid to make it neutral.

Contaminants can cause unexpected results and lead to the creation of unwanted products if the materials you use react with the impurities on the glassware. There is also the risk they may reduce the useful life of buffers and reagents and cause them to become unstable.

Using a laboratory glassware washer from Miele will help safeguard your results and ensure your equipment meets the required standard of cleanliness for whatever experiments or research you might be undertaking.
