Drying Oven SLWN 32

POL-EKO Laboratory Drying Oven SLWN 32 The SLWN 32 is a professional 32-liter benchtop drying oven designed for gentle heating, glassware drying, and sample preparation. Utilizing natural air convection and a wide temperature range of ambient +5?C to +300?C, it provides a stable thermal environment without the use of a fan, preventing sample dispersal. Managed by the Smart 4.3-inch touchscreen controller, it features intuitive programming, an “Alarm Bar” for visual status monitoring, and integrated data logging via USB/LAN. Its high-grade acid-proof stainless steel interior and compact design make it a perfect fit for pharmacies, research labs, and clinical settings.

Description

The POL-EKO SLWN 32 is designed for high-precision laboratory tasks where “quiet” air is a necessity. Unlike forced-air models, the SLWN series relies on Natural Convection (N), where air circulates through the chamber via thermal buoyancy (gravity). This makes the unit the ideal choice for drying fine-grained chemical powders, light biological tissues, or delicate electronic components that could be scattered or contaminated by high-velocity fan air.Smart Control and Data Integrity:Despite its compact size, the SLWN 32 does not compromise on technology. It is equipped with the Smart controller, which offers:User-Friendly Interface: A 4.3-inch color touchscreen that displays current and set parameters clearly, even from a distance.5Complex Profiles: Users can program multi-segment temperature-time profiles, including adjustable ramps and loop functions for automated testing cycles.6Connectivity: Built-in USB and LAN ports allow for the easy export of data logs and event registries, ensuring your processes meet GLP (Good Laboratory Practice) standards.7Visual Alerts: The integrated “Alarm Bar” uses color-coded light strips to show the oven’s status at a glance: Blue (Heating), Green (Stable), or Red (Alarm).Superior Build Quality and Safety:The chamber is manufactured from acid-proof stainless steel (DIN 1.4301), providing excellent resistance to chemicals and high temperatures.8 For safety, the oven includes Class 2.0 over-temperature protection (according to DIN 12880), which automatically cuts the heater if the temperature exceeds safe limits.9 The unit also features an adjustable $emptyset$40 mm air-flap to control the exhaust of moisture and a $emptyset$9 mm access port for external validation sensors.+1Primary Applications:Powder Drying: Moisture removal from fine chemical or pharmaceutical powders.Biological Samples: Gentle drying of plant tissues or paper-based samples.Electronics: Curing and thermal testing of lightweight components.General Laboratory: Sterilization and drying of glassware where fan noise is undesirable.

Specifications

POL-EKO SLWN 32 Drying Oven Specifications

The SLWN 32 is a compact 32-liter laboratory oven that combines forced air convection with a nitrogen blow system. It is specifically designed for applications requiring an anaerobic environment to prevent sample oxidation, such as moisture determination in coal (ISO 589:2003) or the heat treatment of sensitive electronic components.
