"Choice is greater than hard work." This is what Xu Hening said to all those who have dreams. "Choice is greater than effort" This is what I want to say to all users of constant temperature and humidity boxes today. When you try to improve or find out the shortcomings of the product, you want to say that you have to do an environmental test first, first come to a high temperature, come to a low temperature, and then come to a hot and humid cycle, work together, where the product needs improvement, where to consider There are numbers. But the problem is how to choose a suitable constant temperature and humidity box, then you can start from these three systems now, and then look down.
First, the humidification system
The constant temperature and humidity chamber naturally focuses on the humidification system. In the environmental test equipment industry, the humidification system is currently divided into two types, shallow trough and boiler type. Nowadays, the shallow trough type humidification method is widely used, which not only humidifies quickly but also stabilizes. More importantly, it is convenient for customers to replace parts. In addition, pay attention to the humidification tube selected. The humidification tube is made of stainless steel, titanium alloy, nickel-chromium alloy, etc. It is more reasonable to choose the corrosion-resistant material in the water for a long time.
Second, the lighting system
The illuminator is generally of the Philips brand, which can be turned off or on on the control panel, and then automatically turned off for a long time. The installation place is more stressful, some are installed on the left side of the studio, some are installed on the door, and some are installed on the top of the studio. The applicability is naturally related to the test parameters. If the temperature is high and humidity for a long time, such as double 85, double 90 test, it is recommended to choose to install on the door, high temperature and high humidity wet weight, sealed good lighting for a long time to deal with high humidity, naturally it is bad, and installed on the door means observing Between the multi-layer tempered glass of the window, this is equivalent to completely separating the moisture in the work room, and it is also convenient to replace.
Third, the water way
Constant temperature and humidity box naturally add pure water, resolutely suppress tap water, not to mention how much impurities in tap water, it is said that the scale in this tank is enough to clean for a long time. The most important thing is the installation location of this hydration system. Of course, it is necessary to separate the water and electricity. The safety of the equipment is the first. It is not safe to think of water and electricity together. There are drawers, funnels, and The earliest electric control door on the right side of the industry is directly poured into the water tank. This is necessary to open the electric control cabinet door to add water. As for the drawer and the funnel type, according to the actual situation of the user, choose Aesthetic and convenient, consider the funnel type. It is placed on the back of the machine, flush with the back sealing plate, no bumps and traces. If you don't look carefully, you can't find it. The drain valve is also naturally on the back. It also saves a lot of water pipe distance directly connected to the sewer. .
You don't want to ask me why I didn't mention the refrigeration system? Is it really necessary to mention this refrigeration system? The same single-machine refrigeration or dual-machine refrigeration, the same Taikang compressor, the same, the same overpressure protection, overload Protection, etc., look at what features are available. If you choose the right one on these three systems, it is equivalent to buying a guarantee. The stability of the equipment must not only start from any refrigeration system or control system. The details are important, the details are important, the details are important, and important things are said three times.

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
