Sustainability for Pipette Tips & Boxes

Liquid-based samples need to be transferred by pipettes. For accurate and clean sample transfer, single-use tips made of polymers are used. For the last decades, these polymer-based consumables are indespensable in molecular labs. Constant quality levels combined with sterility and acceptable costs are mandatory for reliable scientific results.

How can I find sustainable tips, racks, and boxes?

Waste & recycling
These consumables like tips and boxes are a challenge in respect to sustainability. Labs producing bags full of used consumables are a common situation. They produce waste that is a mixture of different polymers like polypropylene, polystyrole, polyethylene, etc. On top, there is the challenge of potential bio hazards and chemical hazards within this waste. Recycling of plastic lab waste is currently a big challenge with no established technology available.

Biopolymers & recycled raw material
The other big topic of consumables addresses biopolymers and recycled polymers as starting material for consumable production instead of using oil based polymers.

Consumables based on recycled polymers or biopolymer still do not perform in the same way as consumables produced with oil-based polypropylene. Despite a lot of R&D efforts, performance and sterility levels of lab consumables based on alternative material do not fulfill the high expectations of the scientists in the lab in combination with realistic costs for these consumables.

Reduce packaging waste
The usage of refill systems for pipette tips is a good starting point to reduce the amount of plastic waste. These tips are available either as bulk ware in bags or as a replaceable reload system, which is placed on top of a box. By the way, a box is quite durable and can be autoclaved up to 100 times, a rack up to 10 times.

Future
There will be alternative production methods in the future, and our R&D experts do their very best to improve – but it still needs time for consumables based on recycled polymers or biopolymers.
