Chromatography Cabinet Selection Guide
Chromatography Cabinet Selection Guide
1. Market Overview
The chromatography cabinet is a niche product. There are some companies in this product, but they are not the main products. The early products were completely focused on the chromatographic function, mainly in the chemical field, the development of the later life sciences, the prevalence of molecular biology and various scientific fields, and the increasing use of chromatography in various fields, related products. There is a big development.
With the changes in users' needs, there is now a shift from single function to multi-function. The products represented by the thermoelectric company Revco brand have led the trend. There are also many brands in the country, which are catching up, such as the multi-functional creature launched by Xiamen Guoyi. The experimental chromatography cabinet takes into account the dual functions of traditional chromatography and drug preservation, which greatly provides the use efficiency of the chromatography cabinet, and each brand has its own characteristics.
2 , selection steps
The first step: to see if it is versatile, including two functions of chromatography cabinet and drug storage box, flexible switching
Considering that there are not many daily chromatographic experiments in the laboratory, most of the laboratories only put small equipment into the chromatography cabinet. The preservation of medicines, reagents, etc. is the basic requirement that every laboratory needs, so it is multifunctional. The chromatography cabinet can greatly improve its efficiency and reduce costs.
Step 2: Compare temperature uniformity
The smaller the value, the more uniform the temperature in the cabinet, and the stronger the protection of the sample, the better the effect; the temperature uniformity is preferably ±1 degree.
Step 3: View the compressor brand used in the refrigeration system
At present, the refrigeration industry compressor brand is danfoss (Danfoss) [domestic for secop], which is the best reputation. Most of the laboratory refrigeration equipment uses the brand, such as most ultra-low temperature refrigerators, and the price of this brand is generally It is 2-3 times for other brands; the second line contains some Copeland (hot thermo to find them customized), France Taikang, the third line such as Zanussi, the domestic Cannes and so on.
Step 4: Looking at the aerodynamic design of the cabinet, whether it can form a stable active cold airflow covering the entire cabinet, generally need to design the air duct separately to ensure that short-circuit airflow will not be formed to ensure high temperature performance indicators.
Step 5: See if the accessories configured in the equipment are complete.
Can I configure the rack? To achieve the purpose of both chromatography and drug preservation, to improve the efficiency of the use of the cabinet;
Whether to configure the column fixing column and clip, whether it is convenient to use, does not take up space;
Is the internal power socket configured for waterproof performance?
Is the shelf configured to place the instrument on it?
The fifth step: after-sales service
At present, most of the brands are sold in the form of dealers getting goods. In this way, dealers and manufacturers basically buy and sell at one time, and subsequent after-sales service is difficult to carry out. It is best to choose which brand has a fixed agent, the cooperation relationship between the agent and the manufacturer is relatively stable, and the after-sales guarantee.
