The Labselect PTSL ULT undercounter freezers offer storage from -40 °C to -86 °C. The 51 and 100 litre models are suitable for placement under a laboratory bench. Both units are fitted with USB data storage, RS485 and alarm contact. Suitable for clinical and scientific applications.
The Labselect PTSL ULT undercounter freezers are designed for storage between -40 °C and -86 °C. The PTSL51UFU and PTSL100UFU models are suitable for placement under a laboratory bench, making them ideal for personal use in the lab. The freezers are suitable for clinical, medical and scientific environments.
Both models are equipped with 70 mm insulation, of which 25 mm consists of VIP panels. The cooling system uses hydrocarbon refrigerant. Temperature stability is 0.1 °C at a setpoint of -80 °C. Uniform temperature distribution is ±3 °C or ±4 °C depending on the model.
The freezers are supplied as standard with a USB port with data storage up to 15 years. An RS485 port and potential-free contact are integrated. A port for external sensors is present. The models are stackable if multiple units are placed at the same location.
