Design Features

-The LS300 has been designed with all ergonomic concepts in mind. All the components are processed with computer numerical controlled machining centers

-Specimen retraction function, protects specimen from blade damage

-Fast Trim/Cut function makes it easy to switch from trim and section mode -Unit is equipped with counter to calculate total pieces cut and total thickness.

-Dual compressors, which are made in Germany, freeze the cryostat chamber, freezing shelf, knife holder and specimen clamp separate with environmentally friendly refrigerant (R404) Danvers compressor refrigeration, fast freezing and lower noise. Pro-environment—environmentally friendly refrigerant --R404A.

-Chamber temperature can drop to working condition in 60 minutes after switching on.

-Wide freezing shelf may hold 10 specimen cassettes

-UVC sterilize function -Peltier may switched be on or off manually.

-Unit contains heated, removable sliding window. -Unit has two defrost methods: definite time and manual

-The high-precision microtome is enclosed outside the cryostat chamber to protect it from thermal expansion and contraction and keeping service and maintenance to a minimum. -Self-explanatory symbols for all functions and displays make the unit easy to learn and operate.

-LCD screen can display data such as sample travel, thickness, function controlling, day, time, temperature and time on/off. -Suspend mode, after initialization, the temperature in cryostat chamber can be controlled between -4℃ and -9℃ by computer automatically; once stopped initializing, the temperature in freeze chamber will arrive to working temperature within 10 minutes

-Control panel with locking function to avoid improper operation. -Handwheel locking Technical Specifications Freeze chamber temperature range：-10℃～-30℃ Specimen temperature range: -10℃～-30℃ Cool down time to -30℃：60 min Freeze shelf minimum temperature：-45℃ Lowest temperature of Peltier unit on freeze shelf：-55℃ Peltier working time: 15 minutes Maximum specimen size：35mm×35mm Specimen vertical stroke：60mm Specimen horizontal stroke：20mm Coarse feeding speed: 0.7mm/s; 0.35mm/s Section thickness range： 1μm～80μm adjustable; 1μm～20μm, in 1μm increment 20μm～40μm, in 2μm increments; 40μm～80μm, in 5μm increments Trimming thickness range：10μm～400μm adjustable; 10μm～50μm, in 5μm increments; 50μm～100μm, in 10μm increments; 100μm～400μm, in 50μm increments; Retraction range: 0μm～80μm adjustable; in 5μm increment Voltage and frequency：AC220V±10% 50Hz(Standard) ，AC110V±10% 60Hz.
