Abstract:
A cytofunnel arrangement comprising a specimen funnel, a slide and a slide holder, the slide holder being integrally connected with the specimen funnel to form a unit and being adapted for destructive separation from the specimen funnel along predetermined lines or regions to allow extraction of the slide undamaged, whilst preventing re-use of the specimen funnel and slide holder, a separation filament being incorporated between the specimen funnel and the slide holder and terminating in tab means which can be gripped and pulled to pull the separation filament from the unit in such a way as to divide the slide holder from the specimen funnel, and wherein said separation filament is an electrical resistance wire which has been used to weld the specimen funnel and the slide holder together by passing current through the wire to heat the same and thus effect said welding by electrofusion welding.
