Glass injection vials are a common type of pharmaceutical packaging in clinical settings.

　　Glass injection vials are a common type of pharmaceutical packaging in clinical settings. Due to the special nature of pharmaceuticals, the country has strict requirements for packaging materials. The stability of glass material makes it a high-quality packaging option for drugs that need to be stored for a period of time, so pharmaceutical glass injection vials are widely used as drug carriers in clinical practice.
　　The country has introduced many standards and policies to regulate and require the quality of pharmaceutical glass injection vials. Below, the Qingdao injection vial manufacturer will interpret which items need to be tested for pharmaceutical glass injection vials according to the new pharmaceutical packaging standards, what testing instruments are used for pharmaceutical glass injection vials, and the water resistance of glass particles is a routine testing item for glass products.
　　1. Crush the injection vials into small pieces, take an appropriate amount and place it in a mortar, insert the pestle, and strike the pestle hard once with a hammer.
　　2. Transfer the glass from the mortar to the upper layer of the sieve set on the O sieve, and repeat the above operation.
　　3. Vibrate the sieve set with a vibrating sieve machine (or shake the sieve set manually) for 5 minutes.
　　4. Transfer the glass particles that pass through the A sieve but remain on the B sieve into a weighing bottle, with more than 10g as the standard, preparing a total of 3 samples.
　　5. Use a magnet to remove iron filings from each sample of glass particles and transfer them into a 250ml conical flask.
　　6. Wash the injection vial particles with anhydrous ethanol by swirling at least 6 times, 30ml each time, until the anhydrous ethanol is clear.
　　7. Place the conical flask containing the glass particles on a heating plate to remove the residual anhydrous ethanol.
　　8. Transfer to an oven to dry, take out, cool in a desiccator, and the storage time should not exceed 24 hours.
　　The above is the testing method organized by the Qingdao injection vial manufacturer. I hope it is helpful to you and that you pay more attention when purchasing.
