Laboratory temperature control
In the laboratory monitoring project, different laboratories have requirements for temperature and humidity, and most of the experiments are carried out in a clear temperature and humidity environment. The laboratory environmental conditions directly affect the results of various experiments or tests, each The experiment requires accurate and reliable monitoring instruments to provide accurate environmental parameter data.
The element of environmental temperature and humidity control is to ensure that the ambient temperature and humidity of the experimental operation can meet the needs of the various processes of the experimental procedure. We mainly develop the temperature and humidity control range of the laboratory environment from the following aspects.
First, identify the requirements for ambient temperature and humidity for each job.
Mainly identify the needs of the instrument, the needs of the reagents, the needs of the experimental procedure, and the humanization considerations of the laboratory staff (the human body feels comfortable at a temperature of 18-25 ° C relative humidity in the range of 35-80%, and from a medical point of view There is a certain causal relationship between dry environment and inflammation of the throat. The four aspects are comprehensively considered, and a list of requirements for temperature and humidity control is listed.
Second, select and develop an effective environmental temperature and humidity control range.
Extract the narrowest range from the list of all requirements of the above elements as the allowable scope of the laboratory's environmental control, formulate management procedures for environmental condition control, and formulate reasonable and effective SOPs according to the actual situation of the department.
Third, maintain and monitor.
Through various measures to ensure that the temperature and humidity of the environment are within the control range, and monitor and record the monitoring of the ambient temperature and humidity, take measures in time to exceed the allowable range, turn on the air conditioner to adjust the temperature, and open the dehumidifier to control the humidity.
Take a laboratory as an example:
Reagent chamber temperature 10-30 ° C, humidity 35% -80%
Sample storage room temperature 10-30 ° C, humidity 35% -80%
Balance chamber temperature 10-30 ° C, humidity 35% -80%
Moisture chamber temperature 10-30 ° C, humidity 35%-65%
Infrared room temperature 10-30 ° C, humidity 35% -60%
Central laboratory temperature 10-30 ° C, humidity 35% -80%
Sample chamber temperature 10-25 ° C, humidity 35% -70%
During the pathological experiment, the use of microtome, dehydrator, dyeing machine, and electronic celestial instrument have strict requirements on temperature. For example, an electronic balance should be used as much as possible under conditions where the ambient temperature is relatively stable (temperature changes are not more than 5 ° C per hour). Therefore, the temperature and humidity conditions of such laboratories need to be monitored and recorded in real time. The DSR temperature and humidity recorder provides accurate temperature and humidity recording data, which is helpful for the smooth progress of various experiments.
Strict requirements for temperature and humidity environment Under normal circumstances, the cold is 2 ~ 8 ° C, the shade is not more than 20 ° C. Excessive or too low temperatures for antibiotics can lead to inactivation of antibiotics, and the inactivation temperatures of different types of antibiotics vary. Therefore, monitoring and recording of temperature and humidity recorders in such laboratory environments is an important part.
Chemical testing room
The chemical laboratory encompasses a variety of laboratory rooms, such as chemical testing rooms, physical testing rooms, and sampling rooms. The temperature and humidity standards of each room are different. Each room needs to be designated to be monitored regularly. The monitoring frequency is usually twice a day. Using the DsR temperature and humidity recorder, through the professional networking connection, the staff can view the temperature and humidity of each laboratory in the center console, download and save the temperature and humidity during the experiment.
Experimental animal room
The environment of animal laboratories is mainly based on experimental animals. The humidity should be maintained between 40% and 60% RH. It is inverted by mice. If they live in an environment with a relative humidity of less than 40%, they will easily die and die. DSR temperature and humidity differential pressure recorder can establish temperature and humidity monitoring and recording system through network alarm and other measures, which is beneficial to the control of animal room pressure difference and temperature and humidity. Prevent the spread of disease and avoid mutual infection of animals.
Temperature and humidity have a fixed influence on the performance of some building materials, so the environmental conditions for material testing are clearly defined in many standards and must be observed. As specified in GB/T1 7671 1999, the laboratory temperature should be stable at 20 °C ± 2 °C and the relative humidity should not be lower than 50% RH. Use DSR temperature and humidity recorder. It can establish a set of temperature and humidity monitoring and recording system according to the laboratory's own conditions to strengthen the temperature and humidity control of the laboratory.
Certification and Metrology Laboratory
In the implementation of inspection, identification, testing and certification services, the certification and measurement laboratory needs to record and test the changes of temperature and humidity in the whole process in real time. The DsR temperature and humidity recorder can simplify the recording work, save costs, and record data will not be excessive. The interference of human factors can objectively and truly reflect the detection process. Whether the test environment and equipment control the temperature and humidity accurately or not has a significant impact on the accuracy and repeatability of the experimental results. GLP, GAP, CNAS, ISO17025, ISO15189, ISO17020, ISO9000, ISO16949, ISO14000 and other certifications are the basic requirements for the laboratory environment. ZOGLAB products meet the requirements, precision monitoring and provide high-precision original records that cannot be tampered with.
