Laboratory-scale Preparation Testing

Laboratory-scale preparation testing of formulations varies widely by formulation type. The preparation laboratory of BOC Sciences is equipped with small-scale equipment corresponding to various dosage forms such as oral, injection, and external use, including hot melt extruder, wet mixing granulator, dry granulator, high-efficiency coating machine, tablet press, freeze dryer, spray dryer, etc.


Laboratory-scale preparation testing is mainly engaged in exploratory, developmental work, method development and optimization. Laboratory-scale preparation testing is a comprehensive and systematic reform of the original synthetic routes and methods in the laboratory. On the basis of the reform, through batch synthesis in the laboratory and accumulating data, a synthesis process route that is basically suitable for pilot production is proposed. The research at this stage focuses on the key issues affecting industrial production, such as shortening the synthetic route, increasing the yield, simplifying the operation, reducing the cost and safe production.

Laboratory-scale Preparation Testing

Main Mission

  • Determine the best synthetic route

The optimal synthetic process route has the advantages of short synthetic steps, high total yield, simple equipment technical conditions and technological process, abundant and cheap raw material sources, and the like.

  • Find the best reaction conditions and processing methods suitable for industrial production

Laboratory-scale preparation testing can determine whether the use of industrial-grade raw materials and solvents interferes with the reaction and affects the yield and quality of the product. Test to find out the best reaction conditions and processing methods suitable for production with industrial-grade feedstocks.

  • Recovery of raw materials and solvents

Through laboratory-scale preparation testing, a method for recycling raw materials and solvents was found, and the data obtained showed that the use of recovered raw materials and solvents for production did not affect the quality of the product. The recovery of raw materials and solvents reduces costs and is environmentally friendly.

  • Safe production and environmental protection

Laboratory-scale preparation testing will try to screen out synthetic routes that are non-toxic, harmless, non-hazardous, and environmentally friendly. If safety hazards or environmental pollution cannot be avoided, this stage will also look for corresponding protective measures and methods to deal with environmental problems.

Service Process

  • Preparation

1. Verify that the instruments required for experiments and inspections are in place.

2. Select suitable raw materials and excipients.

3. Carry out compatibility tests of raw materials and excipients to study the interaction between drugs and between drugs and excipients.

4. Find literature and reduce time for lab-scale testing.

5. Conduct preliminary quality studies.

  • Testing

1. Prescription process design: According to the characteristics of the dosage form and the properties of the drug, several basic prescription processes are formulated.

2. Sample preparation was performed according to the designed formulation process.

3. Evaluation of the basic performance of the formulation process: the basic performance of the formulation is examined, and if the formulation is not qualified, the formulation process needs to be redesigned.

  • Formulation Process Feasibility Assessment
  • Process Scale-up and Reproduction

1. A scale-up test is carried out on the determined formulation process to ensure that it finally meets the requirements of the pilot test.

2. In order to ensure the consistency of preparation quality, process reproducibility test is carried out.

3. The influence factor test of the enlarged sample and the compatibility test of the inner packaging material.

4. Quality research.

5. Evaluation of laboratory scale preparation test results.

6. Lab-scale preparation testing concluded.

In laboratory-scale preparation testing, BOC Sciences focuses on mixing uniformity, particle flow, and the potential for segregation during tableting or filling, in addition to final product quality.
