Used VARIAN Filament Evaporator #9155355 for sale

VARIAN Filament Evaporator is an evaporator designed to provide a reliable, precise, and consistent method of evaporation of liquids or solids from a variety of sample holders. It is a thermally efficient evaporator with a cold finger, filament supports, and a vacuum bulb filled with inert gas to reduce or eliminate sample oxidation. Filament Evaporator is ideal for transferring liquids or powders from one container to another in an asceptic and efficient manner. The evaporator is designed with a dual filament support, which has a tungsten filament at the bottom and an inbuilt graphite filament at the top. The tungsten filament provides the ultimate in thermal stability and resistance to oxidation, and the graphite filament allows for faster heating and higher temperatures. The core of the evaporator consists of a cold finger that is insulated from the inside surface of the evaporator, which prevents overheating and enables more efficient and reliable evaporation. The cold finger can be thermostatically controlled, allowing for precise temperature control. VARIAN Filament Evaporator features a keyless drive system, which allows for accurate and consistent motion control when entering and exiting the filament support area. This enables an even and efficient evaporation across the entire sample holder, and helps minimize oxidation of the sample. Additionally, the evaporator has a unique vacuum bell configuration which provides accurate and reliable control over the evaporative rate. The bell is also equipped with a safety thermostat to protect against overheating and failure of the evaporator. Filament Evaporator is designed with a highly reflective inner chamber, for maximum efficiency when evaporating samples. It also features an adjustable aperture mirror to better focus the evaporative beam, resulting in faster and more even evaporative rates. Lastly, the evaporator is designed to accept interchangeable workholders, allowing for the processing of different sample holders. In summary, VARIAN Filament Evaporator is an advanced and reliable evaporator featuring a dual filament support, cold finger, and keyless drive system for accurate and efficient evaporation. It is designed with an adjustable thermostat, a highly reflective inner chamber, and a unique vacuum bell configuration, for optimal results. It is also equipped with a safety thermostat and an adjustable aperture mirror to protect against overheating and maximize evaporation efficiency.
