Biochemical incubators are a common sight in laboratories and among environmental protection operators, but for those in the role of purchasers, these machines may seem somewhat unfamiliar. However, choosing the right biochemical incubator is crucial to ensure efficient operations and reliable results. When making a purchase, buyers often engage in thorough research and consultations with biochemical incubator manufacturers. This diligence stems from the fact that the prices of biochemical incubators can vary significantly, with higher quality models naturally commanding a premium. If the price difference isn't substantial, the craftsmanship of the incubator may not differ greatly. To make a cost-effective and high-quality purchase, consider the following key factors:
1. Compressor Type:
The compressor plays a central role in the biochemical incubator, as it controls the refrigeration temperature. Currently, the two most common types of compressors in the market are fluorine-free and fluorine-containing. Increasingly, mainstream biochemical incubators are adopting fluorine-free refrigeration.
Fluorine-free compressors typically use R134a refrigerant, which is environmentally friendly, as it does not harm the ozone layer, has no greenhouse effect, and offers energy-saving and efficient cooling. These compressors have a high latent heat of evaporation, strong cooling capacity, low power consumption, and compatibility with various compressor lubricants.
Fluorine compressors, on the other hand, rely on freon as a refrigerant, which can contribute to ozone layer depletion. Given the importance of the ozone layer in protecting against harmful ultraviolet rays, finding alternatives to fluorine is essential.
While the principles of both compressor types are the same, the refrigerants they use differ significantly, leading to varying costs and, consequently, different prices for biochemical incubators.
2. Temperature Control Range:
Select a biochemical incubator with a temperature control range that suits your experimental requirements. Options typically range from room temperature +5°C to 60°C, 0-60°C, 4-60°C, and 5-50°C. Standard biochemical incubators usually maintain a constant temperature between 5-50°C, while low-temperature biochemical incubators can achieve temperatures as low as -10°C.
3. Incubator Volume:
Biochemical incubators are available in various volumes, including 80L, 150L, 200L, 250L, 300L, and 400L. Choose a size that aligns with your laboratory's needs.
4. Refrigerant Choice:
In today's environmentally conscious world, opting for a biochemical incubator that uses a fluorine-free refrigerant is advisable, considering its positive impact on environmental protection.
5. Power Consumption:
Consider the power rating of the biochemical incubator, as it directly affects electricity consumption. Lower power consumption can lead to cost savings, especially with the rising cost of electricity.
6. Dimensions:
Evaluate the incubator's dimensions, including its internal and external measurements and packaging size. Ensure your laboratory can accommodate the incubator, and that the internal dimensions are suitable for your specific experiments. If you require a large incubator, confirm that your laboratory's door dimensions can accommodate it.
7. Temperature Control Accuracy:
Examine parameters such as temperature fluctuation, resolution, and uniformity to ensure they meet your experimental requirements.
8. Technical Guidance and After-Sales Support:
If you lack experience with biochemical incubators, consider whether the manufacturer offers technical guidance from engineers to help you use the equipment proficiently. After-sales service is crucial due to the high cost, size, and weight of these machines, as transportation and maintenance can pose challenges. Verify the warranty terms and the availability of on-site technical support and services.
By carefully considering these key factors for choosing the right biochemical incubators, purchasers can acquire the product which meets their laboratory's needs effectively.
