Sanotac provides medium pressure preparative chromatography glass columns, medium pressure glass columns, and medium pressure chromatography columns specifically designed for use with medium pressure preparative chromatography

Product features (non bacterial):
1. The unique horn shaped column head is superior to traditional sieve plate design, based on the principle of mixing samples, making sample distribution more uniform, effectively increasing the sample loading volume, and improving separation efficiency. The sample size should be at least 5 times that of a regular high-pressure HPLC preparation column of the same model.
2. Replacing the sieve plate with a nozzle, especially for solid sampling, can effectively prevent damage to the column bed caused by high mobile phase line velocity.
3. The stainless steel jacket with inner lining glass tube replaces the traditional six way valve quantitative ring, which is particularly beneficial for the separation and preparation of high concentration samples, completely eliminating the phenomenon of high concentration samples blocking the valve interface.
4. The characteristic column glass has a performance comparable to stainless steel material. By coupling the chromatographic column and pump system through an adapter, it is possible to complete chromatographic preparation operations from low pressure to high pressure.
5. Fill with 35 micron C18 packing, and one system can complete the daily separation and purification of over 95% of various organic compounds.
6. Filling with 40-50 micron C18 fillers is the preferred method for drug impurity enrichment and separation. The target of capturing 10-100 milligrams of drug impurities can be solved within 1 hour.
7. Humanized column tube design makes it easier for operators to disassemble and wash the packing themselves, greatly reducing the cost of separation hardware.
8. Fast speed, low cost, simple operation, powerful functionality, and innovative design will bring high work efficiency and a pleasant mood to operators.
Specifically, the transparent property of glass allows operators to intuitively understand the separation status of colored samples such as natural extracts and pigments, making their work more fulfilling.

There are also supporting column installation machines available:
Fill any type of glass column with a silicone matrix of 15 microns or more.
Driven by gas at a pressure of 10 kilograms, it can even be operated directly using cylinder gas.
Achieve column efficiency close to high pressure with medium pressure.
Compact structure, easy operation, and convenient use.
