VitalScreen™

Vitality stain

The eosin-nigrosin staining technique is based on the principle that dead cells will take up the eosin and as a result stain red. The nigrosin provides a dark background which makes it easier to assess the slides. The VitalScreen™ is based on the test procedure described in the WHO laboratory manual (2010).

VitalScreen has a 24 month shelf life from date of produce.

VitalScreen™ has been CE marked according to the specifications set forth in the European Medical Device Directive 98/79/EC.
