The Fully Automatic Microtome YD-355AT provides utmost reliability, user benefit and outstanding operator comfort. Great basic stability and precision, make this microtome a real multi-purpose instrument that meets the requirements both in paraffin and hard sectioning techniques of the biological, medical and industrial lab Product specifications : •Fully automatic or manual model，Its two-in-one design concept, which allows motorized and manual sectioning, provides reproducible high-quality sections. •Adopted Germany motor drive ensure slice more precisely ,more reliable and quiet. •The touch screen shows slice and trimming thickness ,section counter ,mode and speed, stroke distance •Special function of specimen retraction which avoid the damage due to the attrition between sample and the back of knife so that the sectioning is more smooth and the life of the knife is more longer . • Model of Blade Carrier for High or Lower Disposable Blades •The hand wheel can be locked in any position to ensure the sectioning as safe and convenient as possible • The waste tray can be disassembled easily •Safety alarm system , overload protection function, sleep mode protection •Universal cassette clamp and standard specimen clamp •Optional Blade carrier which can use Steel Knife or Blade Holder •Emergency stop •Foot Switch to control the Section •Easy operation with Separated Control Panel•Section thickness range: 0.5- 100μm Setting values :From 0.5-2μm in 0.5μm –increments Form 2-10μm in 1μm -increments Form 10-20μm in 2μm -increments Form 20-50μm in 5μm -increments Form 50-100μm in 10μm increments • Trimming section thickness range :0-999μm Setting value : from 0-999μm in 1μm -increments • Cutting speed 0 – 420mm/s • Horizontal specimen stroke :28 mm • Vertical specimen stroke : 60mm • Specimen retraction :12um • Specimen feed speed 1250/2000 μm/s • Precise orientation of specimen clamp • Sample orientation:8°along the X-Y-axis,rotable 360° • Speed of fast forward and Fast backward ：1mm/s • Precision error: ± 5% • Maximum section size: 50 × 45mm • Pole less Speed Regulation function , cutting speed range :0.5mm/s-300mm/s •Voltage and power : 220v / 50Hz  or  110 v /60Hz •Net weight：35kg • Dimensions incl. tray (L/T/H)：500mm（L）X320mm（W）X500mm（H）
