Model: CryoMed Controlled-Rate Freezer 7451

S/N: 506847-130

Description:

This Thermo Scientific CryoMed freezer for controlled rate freezing represents high performance for safe sample freezing being easy-to-program and monitor. It is a front access unit which features an integrated control system (consisting of freezing chamber, microprocessor control and printer – all in one benchtop unit), allowing multiple freezing profiles to be tailored for specific protocols.

Features:

- Freezer is a complete, one-piece system - control panel and thermal printer are integrated, eliminating assembly and connection of electrical components.
- Multiple freezing profiles can be modified to tailor them to your specific protocols.
- Computer enhanced CryoMed Freezer can be created easily by adding a PC, installing a Controlled Rate Freezing PC Interface software.
- Exterior has a powder coat paint finish for a high-quality appearance that resists scratches and chipping.
- Ergonomically designed door handle with vise action latch is easy to grasp for front access to your product.
- Quiet running unit is constructed of Type 304 stainless steel for durability and long life.
- For added security, a modifiable access code (instead of a key) prevents unwanted user profile changes or freezing run interruptions.
- If a power outage lasting less than 10 seconds occurs, the freezer continues to operate without interruption or alarm when power resumes. If the outage lasts longer, the unit continues to operate after power resumes, but an audible/visual alarm occurs, and a message indicates the duration of the power outage.
- Foamed-in-place polyurethane insulation creates an improved R factor that minimizes cabinet condensation, ensuring that there is little moisture to wipe from your benchtop.
- Dual solenoid valves increase LN 2 injection volume, ensuring precise temperature control and accelerated freezing for optimum cell viability.
- Specially designed air handling system and unique liquid nitrogen injection ring (U.S. Patent 6,044,648) work together to ensure optimum temperature control and uniformity.
- Horizontally directed, recirculating airflow allows greater thermal heat/cooling transfer, meeting the requirements of demanding protocols.
- LN2 ring provides a continuous nitrogen vapor supply that ensures optimum, uniform product cooling and prevents premature “seeding”.
- Heating element with overtemperature protection balances controlled freezing and rewarming, minimizing the risk of cell damage.
- Reliable Teflon heat breaks prevent the door from freezing closed.
- High performance bulb-style gaskets ensure a tight door seal.
- Intuitive controls interface ensures that you quickly accomplish new tasks.
- Six preset and 10 user profiles are standard.
- Preset profiles reduce startup time by serving as a starting point when your protocol is unknown.
- Preset profiles can be copied and pasted to create new profiles. These new profiles can be edited and named to meet your protocol requirements.
- 10 user profiles allow 20 steps each for individual, user-created profiles.
- Pre-Cool step automatically starts the temperature ramp when the chamber and sample temperatures are equilibrated within 1 °C, eliminating the need for you to wait and initiate the run.
- Double beep indicates that the Hold time has elapsed, alerting you to a critical time in the run (i.e., “seeding”).
- Programmable chart resolution allows you to define the temp/time scales, making it possible to conserve chart paper.
- At-a-glance chamber and sample temperatures, and operation status allow continuous monitoring and also eliminate confusion about which temperature is displayed.
