FT33MkII Lyophilisateur sous Vide

Le Lyophilisateur Armfield est une unité compacte conçue avec un diamètre chambre de travail isolée de 300mm et une profondeur de 385mm. Il intègre un système de réfrigération et le système de chauffage à température contrôlée. Avec la chambre de condenseur et la chambre de travail construits à partir d'acier inoxydable, il offre une excellente résistance à la corrosion et peut être facilement stérilisé.

The products can be frozen in the chamber before drying.

The unit is designed for freeze drying biologically heat sensitive materiaIs contained in beakers or other vessels.

It can be considered to be a small-scale replica of commercial-scale pharmaceutical and food production machines.

Order Specification

• A vacuum freeze dryer with a top loading working chamber 300mm in diameter and 385mm deep with refrigeration and heating, 210mm diameter refrigerated condenser chamber.
• The chambers have clear acrylic lids for process observation.
• The refrigerant is R507 (non CFC) and the condenser chamber no load temperature is -55°C.
• The working chamber has four mobile temperature probes.
• A membrane panel with touch sensitive switching and liquid crystal display controls refrigeration, vacuum pump, heating and defrost. A vacuum pump with a capacity of 150 litres/minute is provided.

Description

The FT33 Freeze Dryer comprises a cylindrical working chamber 300mm diameter by 385mm depth mounted adjacent to a 210mm diameter condenser chamber in a painted stainless steel cabinet. Both chambers incorporate a clear acrylic lid on an 'O' ring seal. Products to be freeze dried may be frozen in the working chamber prior to drying. Drying rate may be controlled by the application of heat to the working chamber via a heating element with temperature controller.

Ice build up in the condenser chamber can be observed through the acrylic lid. The chamber is defrosted by an electrical heater and the ice plug may be removed whole or via the lid or allowed to melt totally and drained through the drain plug.

A vacuum pump of 150 l/min capacity is supplied and stands beside the freeze dryer. An oil mist filter is fitted as standard.

The refrigeration system will give a no load condenser chamber temperature of -55°C. A thermostatic expansion valve automatically adjusts the extraction rate to handle large quantities of vapour. The unit is provided with magnetic shut off valves, electrical overload and overheat protection devices. A membrane panel with touch sensitive switching and LCD controls refrigeration, vacuum pump, heating and defrost.
