Sample pretreatment is a key step in drug testing, which directly affects the precision and accuracy of the analytical results. Choosing the appropriate pretreatment and shortening the pretreatment time is an important method to improve the testing efficiency while ensuring the quality of the test.

 It’s necessary to choose appropriate pretreatment according to the structure of the measured drug, physicochemical and pharmacological properties, the drug form and concentration range.

 Drug concentration in the sample varies greatly. For the high concentration of sample, the pretreatment requirements can be slightly lower; For the lower concentration of the sample, pretreatment requirements are higher. Selection of appropriate grinding, crushing, sieving solutions can create good conditions for the sample analysis.

ASF epidemic prevention and control sample pretreatment solution-POWTEQ Micro Ball Mill GT300

 African swine fever (ASF) is a deadly pig disease that affects domestic and wild pigs. It is not a risk to human health, but affects animal welfare, causes severe production and economic losses and can threaten food security worldwide. The number of countries or territories affected by ASF has increased in recent years, with notifications from countries in Sub-Saharan Africa, Europe and Asia. It can only diagnose by lab.

 Then here is the question, how the lab make test to diagnose efficiently? Small volume, high throughput, fast process speed are exactly what African swine fever virus (ASFV) DNA extract pretreatment required which Micro Ball Mill GT300 is quite suitable.

GT300 Performance advantage:

• Grinding time extremely short: 30s~1min to grind animal tissue sample
• High throughput design: 192samples at top for a time. There are 5/10/24/48/96 sample process option a time
• Test in high repeatability: test parameter could be pre-set digitally, test result in high repeatability
• Avoid environment pollute sample: grinding in closed sealed grinding container, the sample get no contact with external environment
• Prevent samples cross contamination: micro vials and grinding balls are consumable. It applied to PCR, Probe and so on analysis method which request strictly forbid samples cross contamination.
• Operation with high security: instrument upper lid with security lock, once the lid is open, the motor will stop running to ensure user safety
• 5inch LED display screen

ASFV NDA extract pretreatment solution:

• Sample: pig lymphoid tissue, spleen
• Sample volume: 1g
• Centrifugal tube: 2ml or 1.5ml
• Normal saline: 1ml
• Grinding balls: 2pcs. of 5mm dia. Stainless steel grinding balls
• Speed: 1600rpm
• Grinding time: 1min
• Grinding performance: after grinding, samples be in uniformly pulp
