Extremely high sample throughput rates

Precision and reliability in automated liquid handling

If there’s one thing the COVID pandemic has taught us, it’s that laboratories have a huge demand for high sample throughput rates. Even when a laboratory has highly qualified staff, this demand can no longer be met. There’s no getting around the automation of laboratory processes. That is why Dutch company MolGen has developed the PurePrep TTR, which can prepare 320 patient samples per hour for further molecular processing. And they use laboratory-specific automation technology from Festo.

Rapid growth

During the COVID pandemic, laboratories were set up everywhere because high sample throughput rates were absolutely essential. “This is where MolGen got involved, and in a very short time, within 2 to 3 years, we've grown from five to more than 130 employees”, explains Kruize, Member or the Management Board at MolGen and one of the three founders of the company, referring to subsidiaries in the Netherlands as well as in the UK and the US.

“When we founded MolGen, our primary business area was high sample throughput rates in genetic engineering laboratories for animals and plants. We had a lot of knowledge about the chemicals needed for this", explains Kruize.

Recent developments include the handling unit PurePrep TTR. It is used for automated handling of liquids at high throughput rates by quickly, accurately and reliably transferring them from sample vials to microwell plates. “The automated PurePrep TTR has a throughput rate of 320 samples per hour”, says Kruize. Even laboratory assistants who are well-trained and have lots of professional experience are unable to match this tremendous throughput rate”, he adds.


Laboratory staff for more demanding tasks

Despite the expert skills of trained laboratory staff, errors can still occur and lead to contamination. The individual steps of gripping a sample, unscrewing the cap, putting the cap down, removing the liquid with a pipette and transferring it to a microwell plate are time-consuming and cumbersome. The sample vials as well as the plates are labelled with barcodes that are read by scanners in order to monitor and track the samples throughout the entire work process. “By automating these process steps, we can use our highly qualified laboratory staff much more effectively for more demanding tasks, such as analysing test results”.

Dependable collaboration

“I’ve been working together with Festo for ten years, especially with Festo’s national company in the Netherlands”, reports the Member of the MolGen Management Board. He describes this collaboration as exceptional, because Festo is always prepared to do more than just sell standard products. “Their innovation unit caters to our requirements and provides us with modules for pilot projects. That was the case with the controller CPX-E and now again with the "magic box", as we call it – the decentralised pressure and vacuum generator PGVA”, says Kruize and adds: “We were among the first, maybe even the very first, to use it.”

Decentralised pressure and vacuum supply

“It is more or less hidden in the machine housing”, explains Bert Baas, Dutch sales engineer for laboratory automation at Festo. The PGVA integrates compressor, air preparation including filter system, reservoir and electronic pressure and vacuum control in the smallest of spaces. “In order to meet the huge demand during the COVID pandemic, we supplied MolGen with the pressure and vacuum generator while it was still in the technical approval phase”, reports Baas.

“The PGVA shows how passionate the various teams at Festo always are about automation, and that results in successful collaborative solutions for us. This inspires confidence in their ability to produce prototypes and systems much faster and more flexibly than the competition”, concludes the Member of the MolGen Management Board.
