The Eppendorf Innova U535 ULT (ultra-low temperature) freezer minimizes operating costs while providing superior protection for your critical samples. A combined insulation based on vacuum insulation panels and polyurethane foam enables extremely low energy consumption. When it comes to maximizing sample storage capacity, Eppendorf Innova ULT freezers set the standard. These lab freezers like the Innova U535 take advantage of ultra-efficient, ultra-compact vacuum insulation panels which are used in combination with traditional insulation to slim down the freezer wall thickness from 130 mm to 80 mm. These models are ideal for labs short on space.
