FreeZone® Triad® Benchtop Freeze Dryers are designed for multiple types of lyophilization: flask, bulk and stoppering vials. With the ability to freeze dry samples in so many different forms, the Triad’s versatility and compact design make it perfect for busy labs. Now with Lyo-Works™ OS the Triad is smarter than ever, making freeze drying even challenging samples easy.
Lyo-Works™ OS provides a real time display of collector temperature and vacuum level on a 5" full color, capacitive touch screen. Lyo-Works OS provides storage for up to 30 programs that can hold up to 16 steps each. Display includes navigation to start-up mode, vacuum set point, alerts, diagnostic tests, user manual, and defrost control. Data logging stores and displays data in table or chart format and data may be exported via the side-mounted USB or rear-mounted Ethernet connection. Language can be set to English, Spanish, French, German or Italian. Other settings include time, time zone, temperature (°C or °F) and vacuum (mBar, Torr or Pa). Alerts and feedback of current operating programs can be sent automatically to user-entered email addresses for remote notification even when away from the lab.
The upright stainless steel collector coil holds 2.5 liters of ice before defrosting. Two 1/3 hp HCFC/CFC-free refrigeration compressors cool the collector to -85°C (-121°F), suitable for aqueous or dilute acetonitrile samples. Temperature-controlled shelves range from -55°C to +50°C (-67°F to +122°F) and a maximum of -75°C (-103°F) during pre-freezing. The shelves provide pneumatic stoppering with a diaphragm, eliminating the need for compressed gas. The space between the processing shelf and top of chamber accommodates containers with stoppers up to 148 mm maximum height. Other triad features include a Pirani vacuum sensor and four valve ports for flasks.
FreeZone exclusive features protect the vacuum pump from damage. A vacuum break valve bleeds air into the system when power to the freeze dryer or vacuum pump is shut off for more than 5 minutes so moisture from the melting samples does not end up in the pump. If the vacuum level is higher than 5 mBar for 30 minutes, the vacuum pump will automatically turn off, preventing pump damage.
Vacuum pump with a displacement of at least 98 liters/minute and freeze dry glassware (if not bulk freeze drying) are required (not included).
