Introduction
A controlled rate freezer is a freezer used for the controlled freezing of the biological samples, such as the cells, the tissues, and the embryos, at the controlled cooling rates, for the cryopreservation, and it is used in the biobanks, the cell culture, the IVF (in vitro fertilization), and the research laboratories. The controlled rate freezer consists of an insulated chamber, a cooling system, which uses the liquid nitrogen or the mechanical refrigeration, a temperature control system, which controls the cooling rate according to the programmed profile, and the sample holders, and it cools the samples at the controlled rates, such as -1 degree Celsius per minute, which are optimized for the survival of the cells, with features such as the programmable cooling profiles, the temperature monitoring, and the data logging; the controlled rate freezer is used for the cryopreservation of the cells, for the cryopreservation of the embryos and the oocytes, for the cryopreservation of the tissues, for the storage of the samples for the research and the therapy, and for many other applications, and it is an essential equipment for the cryopreservation; the controlled rate freezer provides the reproducible and the controlled cooling, which improves the viability of the frozen samples. Controlled rate freezers are used in the biobanks, in the IVF clinics, in the cell culture laboratories, in the research institutions, and for many other applications. With their controlled cooling, controlled rate freezers are essential for the cryopreservation.

FAQ
Q1: What scenarios is this freezer used for?
A: It freezes stem cells, embryos and biological samples at a programmed cooling rate to improve post-thaw viability. Customers in related industries rely on it for routine and quality-control work, and we can match the unit to your intended use.
Q2: What standards does it comply with?
A: It follows medical/cryogenic equipment and related GB/T standards, with temperature and rate verified. Final inspection verifies these parameters before delivery, and the supporting compliance records are available when the order is placed.
Q3: What is the warranty?
A: It carries a 12 to 24 month warranty covering the chamber and controls. Damage from misuse is excluded.
Q4: Is it hard to operate?
A: It requires trained staff for protocols and liquid nitrogen where used. We provide a manual and training.
Q5: What is the lead time?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is calibration required?
A: We recommend verification against traceable standards at regular intervals, typically every 6 to 12 months, and keeping calibration records for audit purposes. The manual describes the procedure, and reference standards are available from us. Accredited third-party calibration can also be arranged on request.
Q7: Are consumables universal?
A: Cryogens are supplied locally, while sensors are model-specific. Ongoing cost includes cryogens.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include chamber size, LN2 or mechanical cooling and data logging. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: No installation is required. The unit is delivered fully assembled and factory tested, so you only need to place it on a level surface, connect power and follow the quick-start guide. An illustrated manual and setup video are included, and our engineers provide remote guidance if needed.
Q10: What samples are compatible?
A: It handles vials and bags within validated protocols. It is not for non-biological storage, samples beyond chamber size, or uncontrolled-rate freezing needs.
