1. Market Overview
Chromatography cabinets are niche products. There are several companies that produce them, but none of them are their main products. Early products focused entirely on chromatography functions, mainly in the chemical field. Later, with the development and growth of life sciences, the prevalence of cross-disciplinary studies in molecular biology and various scientific fields, chromatography applications in various fields became more and more common, and related products developed significantly.
With changes in user demand, there is now a shift from single-function to multi-function. Products represented by Thermo Fisher Scientific's Revco brand have led the trend, and multiple domestic brands are also competing fiercely to catch up, such as Xiamen Guoyi's multi-functional biological laboratory chromatography cabinet, which combines the dual functions of traditional chromatography and drug storage, greatly improving the utilization efficiency of chromatography cabinets. Each brand has its own characteristics.
2. Selection Steps
Step 1: Check if it is multi-functional, including both chromatography cabinet and drug storage box functions, with flexible switching
Considering that daily chromatography experiments in laboratories are not frequent, and most laboratories only place small equipment inside chromatography cabinets, the basic need for storing drugs and reagents is essential for every laboratory. Therefore, a multi-functional chromatography cabinet can greatly improve its utilization efficiency and reduce costs.
Step 2: Compare temperature uniformity
The smaller the value, the more uniform the temperature inside the cabinet, the stronger the protection for samples, and the better the effect; a temperature uniformity of ±1 degree is optimal.
Step 3: Check the compressor brand used in the refrigeration system
Currently, the compressor brand with a good reputation in the refrigeration industry is Danfoss (domestic equivalent is Secop). Most laboratory refrigeration equipment, such as ultra-low temperature freezers, use this brand, and its price is generally 2-3 times that of other brands; second-tier brands include Copeland (Thermo Fisher Scientific customizes from them), Tecumseh (France), and third-tier brands such as Zanussi, and domestic brands like Konor.
Step 4: Look at the aerodynamic design inside the cabinet, whether it can form a stable active cold air flow covering the entire cabinet. Generally, a separate air duct design is required to ensure that no short-circuit airflow is formed, thereby ensuring high temperature performance indicators.
Step 5: Check if the accessories configured with the equipment are complete
Can shelves be configured? To achieve the purpose of both chromatography and drug storage, improving the utilization efficiency of the cabinet;
Are chromatography column fixing posts and clamps configured? Are they convenient to use and do not take up space?
Are internal power outlets configured? Do they have waterproof performance?
Are shelves configured to place instruments and equipment on?
Step 5: After-sales service
Currently, most brands sell through distributors purchasing goods. In this model, distributors and manufacturers typically have a one-time transaction, making subsequent after-sales service difficult. It is best to choose a brand with a fixed agent, as the cooperation between the agent and the manufacturer is more stable, and after-sales service is guaranteed.
