Model: 7455 Controlled Rate Freezer / Programmable freezer 1.7 cfm with LN tank

S/N: 300046857

Year of construction: 2015

incl.:

• Temperature sensor
• Tuberack

Description:

The Thermo Scientific 7455 is a reliable, precisely controllable freezer for controlled freezing of temperature-sensitive biological samples such as cells, tissues, stem cells, vaccines or hybridomas. With a cooling rate of up to 1.7 cfm (cooling capacity) and the ability to program precise freeze profiles, the system meets the highest demands in biotechnology, cell therapy and cryopreservation.

Thanks to microprocessor-controlled temperature control and the use of liquid nitrogen (LN ) the 7455 achieves extremely low temperatures with exact reproducibility. The device enables linear cooling rates over the entire range and stores individual programs for repeatable results.

The integrated pressure tank for liquid nitrogen is included in the scope of delivery, making the system ready for immediate use.
