Monitor and record the temperature of your samples during controlled-rate freezing and cryogenic storage with sensors, recorders and parts from Thermo Scientific. Thermocouple sensors measure the actual sample temperature inside straws and cryovials of 1.2 to 2.0 mL and 4 mL, while chart recorders and recorder paper capture the freezing curve of your CryoMed controlled-rate freezer. Poly Temp Scientific supplies the sensors, recorder kits and bypass and alarm parts with advice, installation and maintenance.

Monitoring, sensors and recorders are the components with which you monitor and record the temperature of your samples during controlled-rate freezing and cryogenic storage. When freezing cells, tissues and biological samples, it is not only the final temperature that matters, but above all the way the sample cools down. A thermocouple sensor measures the actual sample temperature inside a straw or cryovial, while a chart recorder captures the freezing curve on paper. This gives you verifiable proof that the freezing protocol was carried out correctly. In this category you will find the sensors, recorders and accessories from Thermo Scientific for the CryoMed controlled-rate freezers, supplied with advice, installation and maintenance by Poly Temp Scientific.
During controlled-rate freezing in a CryoMed controlled-rate freezer, the chamber temperature follows a programmed profile, but the temperature inside the sample itself always lags behind it. In particular, the moment the heat of crystallisation is released (the phase change from liquid to solid) causes a brief temperature spike inside the sample. To maximise cell survival, that spike must be kept under control.
That is why you use a thermocouple sensor to measure the temperature directly inside a representative test sample, a straw or cryovial identical to the rest of the batch. The freezer can then adjust its cooling based on the actual sample temperature and not just on the chamber temperature. The recorder captures both curves, so you can afterwards demonstrate that the protocol ran as planned.
Our range consists of sensors, recorder parts and safety components for the CryoMed controlled-rate freezers from Thermo Scientific. Below you will find the function and application for each group.
Thermocouple sensors and probes: sensors that measure the sample temperature inside a straw or cryovial. There are versions for straws and for cryovials of 1.2 to 2.0 mL and of 4 mL. You place the sensor in a test sample that freezes along with the batch, so the freezer controls on the actual sample temperature.
T-type thermocouple 6: a type T thermocouple for accurate temperature measurement in the cryogenic range. This sensor connects to the measurement and control electronics of the CryoMed and delivers a reliable signal well below zero.
Recorder paper (chart paper): the consumable on which the chart recorder draws the freezing curve. Original chart paper provides a legible, lasting record of every freezing run for your quality file.
Recorder kit 220V: a complete set to fit a CryoMed with a chart recorder or to replace an existing recorder, designed for 220 volts. This lets you record both the chamber and sample temperature during every run.
Bypass and alarm parts: components for the safe operation of the freezer, such as bypass components and alarm parts that warn you of deviations. Ask our specialists for advice on the right parts for your version.
The choice of component depends on what you want to achieve: measure, record or monitor.
Measure (thermocouple sensor): choose this when you want to measure the actual sample temperature inside a straw or cryovial, so the freezer can control on it. You select the sensor based on the shape and volume of your sample: straw, 1.2 to 2.0 mL or 4 mL.
Record (chart recorder and paper): choose this when you want a lasting record of the freezing curve for your quality file or validation. For this you use the recorder kit 220V and the matching recorder paper.
Monitor (bypass and alarm parts): choose this when you want to safeguard the safe operation of the freezer and be warned in time of deviations during a run.
These components are used wherever biological material is frozen and stored in a controlled way.
Cryobanks and biobanks: the reproducible freezing and documentation of cells and tissues for long-term storage, where every run must be traceable.
Cell and gene therapy: the controlled freezing of cell preparations according to validated protocols, with a record that demonstrates the freezing curve.
IVF and reproductive medicine: the freezing of gametes and embryos in straws, where accurate sample temperature and recording are crucial.
Universities and research institutes: research where the cooling profile of the sample must be reproducible and verifiable.

A thermocouple sensor measures the actual temperature inside a sample, such as a straw or cryovial, during controlled-rate freezing. The CryoMed controlled-rate freezer can then adjust its cooling based on the sample temperature and not just the chamber temperature. This keeps crystallisation under control and keeps the cells as intact as possible.
There are thermocouple sensors for straws and for cryovials of 1.2 to 2.0 mL and of 4 mL. You choose the sensor based on the shape and volume of your sample, so the measurement is representative of the rest of the batch. Our specialists help you make the right choice.
The thermocouple sensor measures the temperature of the sample, while the chart recorder records that temperature together with the chamber temperature on paper. The sensor is therefore for measuring and controlling, the recorder for recording and documenting the freezing curve.
A recorded freezing curve is the verifiable proof that the freezing protocol was carried out correctly. For cryobanks, cell and gene therapy and IVF, that record is a fixed part of the quality file and validation. With the recorder kit 220V and original recorder paper, you capture every run legibly and permanently.
A type T thermocouple is a temperature sensor suited to accurate measurements in the cryogenic range, well below zero. The T-type thermocouple 6 connects to the measurement and control electronics of the CryoMed and delivers a reliable signal during freezing.
Bypass and alarm parts support the safe operation of the CryoMed controlled-rate freezer. Alarm parts warn you of deviations during a run, so you can intervene in time. Ask our specialists for advice on the right parts for your version.
