Keeping the appropriate temperature levels inside an ultrabezoidal freezer is an important aspect to ensure the preservation of stored products. Scientists, restoration companies and laboratories ensure that stored material remains frozen at the correct temperature. These kits were created in order to maintain very low thermal conditions, from -45°C to -86°C, necessary to preserve samples of liquid, living cells and food subject to decomposition due to temperature variations. These fluctuations can also trigger an increase in the rate at which microorganisms develop, which could lead to a sudden accumulation of bacteria and eventually contamination of organic matter.
Characteristics of laboratory ultrabeziers
Control and monitoring of optimal temperature levels in a laboratory freezer is a crucial factor in ensuring proper storage of samples and flammable materials. For this reason, all these units come with a variety of features designed to ensure safe and long-term storage. They commonly feature a robust and well insulated structure, made of stainless steel, sheet steel and/or pressed glass fiber, thus ensuring that the external heat is not transferred to the main cavity. The independent cavities also have double-entry reinforced doors to contain any cold air leakage.
Recommendations for use to keep the temperature inside the deep freezer
- These units are not intended for use in hazardous locations or for the storage of flammable or corrosive inventory. Storage of non-hermetically sealed corrosive substances may cause corrosion inside the unit.
- The freezer should not be connected to a circuit breaker-protected socket for loss of ground, as this may cause unwanted disconnection. It must be connected to a battery-powered protective device to keep it powered on while the power is restored.
- Install the unit in a level, vibration-free area with minimal space
- Do not place equipment under direct sunlight or in the vicinity of heating diffusers, radiators, or other heat sources.
- The unit should be level from front to back and side to side. If the unit is uneven, it can become unstable and cause problems with the doors and drawers.
- Drawers should fit perfectly between the sliders so that they do not interrupt the door closing. Never pass objects through the door lock. If the seal does not close properly, moist air will enter the cabinet.
- Changing any of the control parameters could adversely affect the freezer performance. Before making adjustments to the values of the service parameters, you should make sure you understand the requirements of the product. For this it is necessary that the staff in charge is qualified and trained to configure the control system.
