Spin+Collect Sample Recovery

The Isohelix Spin+Collect™ is a novel sample recovery device to increase sample yields from swabs and other materials. The Spin+Collect firmly grips the swab or other material whilst exposing maximal surface area for the first step of elution or lysis of the sample. A 1.5ml microfuge tube is then fitted as a cap and inverted for centrifugation and final release of any sample trapped in the matrix.


  • Yields increase over 25%
  • Recovers sample deeply embedded in the matrix
  • Only requires a single centrifuge step
  • Disposable, sterile and packaged aseptically
  • Tested for human DNA contamination

Cell Projects Ltd has an exclusive license on patented designs from Guy’s and St Thomas’ NHS Foundation to commercialise the Spin+Collect™ and is jointly working with the Foundation to extend its application and use.
