Tackling Waste: 5 Steps to Less Plastic Waste in the Lab

Life sciences laboratories are another area in which plastic waste can be reduced. Approximately 5.5 million tons of plastic waste are produced every year in life sciences laboratories alone, including items like pipette tips, nitrile gloves, cell culture flasks. In the age of global waste pollution and the ubiquity of plastic in the world around us, this is definitely too much. It can’t all be changed, but improvements are possible in some areas.

Cannabis Analysis

Cannabis Under (Moisture) Control

The determination of moisture in cured cannabis is an indicator of microbial contamination, a key variable used to calculate other constituent results on a dry basis and required for the pressing process of extracting CBD oil from cannabis. Thermogravimetric moisture determination can provide valuable services here.

Clarification and sterile Filtration of Antibodies

Fast Cell Harvesting Without Using a Centrifuge

Whether employed in basic research or the production of biopharmaceuticals, monoclonal antibodies are used in an exceptionally wide range of applications. Until now, harvesting of mammalian cell cultures used to be time-consuming, especially at laboratory scale, and usually involved a centrifugation step. A new diatomaceous earth-based filtration solution now improves and accelerates this process significantly.

Bacterium produces pharmaceutical all-purpose weapon

For some years, an active substance from the leaves of an ornamental plant has been regarded as a possible forerunner of a new group of potent drugs. So far, however, it has been very laborious to manufacture it in large quantities. That could now change: Researchers at the University of Bonn have identified a bacterium that produces the substance and can also be easily cultivated in the laboratory.

Determining if and when a handgun has been fired

Gunshot Residue Dating

To clarify whether and when a handgun was fired, forensic scientists search for and analyze Gunshot Residue (GSR) deposits. One highly interesting aspect of GSR is the presence of volatile organic chemical residues, which can offer clues as to when a weapon was fired. An innovative extraction technique based on Headspace Sorptive Extraction (HSSE) and Gerstel Twister has now been shown to extract additional information from spent cartridges.
