Zenith ATM-400 Series Educational Microscopes

Purpose built teaching instruments of modern design & robust construction ideal for GCSE
biology studies. Excellent optical performance is provided by DIN standard optics. Two
identical models are available with a choice of either a plano-concave mirror or 230v 15w
illumination. Anti-tamper safety features essential for school use include locked-on eyepiece
and stage clips, slip-clutch on the coarse focus movement to prevent over-focussing and an
internal focus-stop to prevent damage to glass microslides and objective lenses.
