Magnetic separating device

A magnetic separating device for isolating magnetically labelled particles from a non-magnetic medium comprising:

• a body portion having a magnetising portion for providing a magnetic field and a surface by means of which the body portion may stand on a supporting surface, the magnetising portion comprising at least one magnet and an external wall on the outer side of the magnetising portion;
• and
• a sample vessel retaining portion for retaining at least one sample vessel,
• wherein,
• the external wall of the magnetising portion is configured to conform to at least a substantial portion of only one side of the longitudinal profile of at least one sample vessel;
• the sample vessel retaining portion is configured to retain at least one sample vessel such that at least a portion of the contents of the sample vessel is visible to a user;
• the sample vessel retaining portion is configured to be mountable on the magnetising portion so that in use, the at least one sample vessel is subject to the magnetic field of the magnetising portion;
• the at least one sample vessel arranged on the outer side of the whole magnetising portion;
• and
• the at least one sample vessel is arranged in close proximity to and in confronting relation to at least one side wall of the external wall of the magnetising portion, when the sample vessel retaining portion retains the at least one sample vessel.
