Bioviewers are tough styrene instruments, almost unbreakable and made for years of wear in classroom conditions.
They can be used in any room at any time or even outdoors.
With BioViewers you can stop worrying about expensive apparatus in inexperienced hands.
They do not need any special treatment or care, they can even be washed. No lamp is needed; the white reflector stage provides sufficient light for a bright image.
