The LEEC P33 Precision incubator combines traditional styling and modern controls for precise temperature control in a large capacity (730 litre) stainless-steel chamber.

(Models P2 and P3 have been replaced by equivalent models from our Classic incubator range).

The P33 Precision incubator has adjustable stainless-steel shelves and 4 toughened glass inner doors. The outer cabinet is rust-resistant and finished in white polyester powder coat paint with anti-microbial properties. Two 12mm access ports are provided so that cables for shakers and/or monitoring probes can be inserted safely into the incubator.

The heating system consists of low wattage electrical elements specially designed and profiled to eliminate hot spots around the chamber. Expanding polyurethane insulation is foamed in-situ to give excellent thermal retention to ensure optimum temperature control and stability.

The P33 incubator can heat only. It cannot cool. Operation near or below room temperature will requires a source of chilled water (such as the LEEC self-contained recirculating cooler unit).  All LEEC Precision incubators (regardless of their age) can cool when connected to an external LEEC Self Contained Recirculating Cooler Unit.

The P33 has gentle twin fan-assisted air circulation via a full-width duct to ensure optimum temperature stability throughout the chamber. When the incubator door is opened, both fans stop so that heat loss is kept to a minimum. The digital temperature controller maintains the set temperature to within 0.1°C and shows both 'target' and 'actual' temperatures in real time, with indicators showing when the heating is active.

An independent digital over-temperature safety cut out system protects the chamber contents from accidental over-temperature situations. The cut-out limit can be easily adjusted by the end-user.
