Construction Standards for Laboratory Sample Retention Rooms
2025.02.12
In the overall structure of a laboratory, the sample retention room, although seemingly unobtrusive, plays a crucial role. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. deeply understands the significance of the sample retention room in ensuring the traceability of experimental data and the accuracy of experimental results. Today, we will take you to delve into the construction standards for laboratory sample retention rooms.
I. The Importance of Building a Sample Retention Room
The sample retention room is a key place for storing backup experimental samples. When there are doubts about experimental results, when re - verification is required, or when subsequent research needs to refer to the original samples, the samples in the sample retention room can play a crucial role. It is not only an important guarantee for the reliability of experimental data but also a necessary facility to comply with relevant regulations and industry standards, ensuring the standardization and scientific nature of the experimental process.
II. Site Selection and Layout Standards
1. Site Selection: It should be located in a relatively independent, quiet, and easily manageable area. Keep away from vibration sources, pollution sources, and high - temperature and high - humidity environments to avoid interference with and damage to the retained samples. For example, it should not be placed adjacent to large - scale mechanical equipment to prevent vibrations from affecting the stability of the samples; it should also be far away from the chemical reagent storage area to prevent the volatilization of chemical substances from contaminating the samples.
2. Layout Planning: The interior of the sample retention room should be reasonably divided into functional areas, generally including a sample storage area, a sample registration area, and a sample processing area. The sample storage area needs to be equipped with sufficient shelves or storage cabinets to arrange samples in an orderly manner according to sample types, batches, etc.; the sample registration area should be set near the entrance for staff to record sample information in a timely manner; the sample processing area is used for simple pre - treatment of samples, such as sub - packaging and labeling.
III. Environmental Control Standards
1. Temperature and Humidity Control: Different types of samples have different requirements for temperature and humidity. Generally, the temperature in the sample retention room should be controlled between 15 - 25°C, and the relative humidity should be maintained between 35% - 75%. By installing temperature and humidity sensors and professional air - conditioning, dehumidifying and humidifying equipment, the indoor temperature and humidity are monitored and regulated in real - time to ensure that the samples are stored in a suitable environment.
2. Air Quality Control: To prevent dust, microorganisms, etc. in the air from contaminating the samples, the sample retention room needs to be equipped with air purification equipment, such as primary - effect and medium - effect filters. If necessary, high - efficiency filters can be installed to ensure that the indoor air cleanliness meets the requirements. The purification equipment of Guangzhou Cleanroom Construction Co., Ltd. can effectively meet the air quality needs of the sample retention room.
IV. Equipment and Facility Standards
1. Storage Equipment: Select sample storage containers with reliable quality and good sealing performance, such as glass bottles and plastic bottles, and choose the appropriate material according to the characteristics of the samples. Shelves and storage cabinets should have good bearing capacity and stability to facilitate the storage and access of samples.
2. Identification and Recording Equipment: Equip clear sample identification plates and standardized record forms to record detailed information such as sample names, numbers, sources, retention times, and expiration dates to ensure the traceability of sample information. At the same time, an electronic recording system can be adopted to improve the accuracy of recording and the convenience of querying.
V. Safety Management Standards
1. Fire and Theft Prevention: Install fire alarm systems and fire - fighting equipment, such as fire extinguishers and fire hydrants, and conduct regular inspections and maintenance. Strengthen anti - theft measures for doors and windows, set up access control systems, and restrict unauthorized personnel from entering to ensure the safety of the sample retention room.
2. Sample Safety: Establish strict sample management systems, standardize the sample entry and exit processes, and prevent sample confusion, loss, or damage. For samples with special safety requirements, such as flammable, explosive, toxic, and harmful samples, special safety protection measures should be taken.
