Checklist for selecting the right vendor for your bottle testing lab

Your products will be selected and rejected on the basis of the right quality testing instruments. Nonetheless, it is tragic that most business owners pay the least attention to the testing facilities. The primary focus is on selecting the right production machines (of course, that's important), or increasing their sales (also important).
Just as production machinery is needed to produce Bottles and Caps, the right instruments are needed to make sure that your bottles and materials comply with international standards and provide the durability expected by the customers. If the quality is compromised, if standardization is not implemented, no matter how much material you manufacture, it is of no use – it is going to get rejected or your customers are quietly going to move to other providers without even informing you what the problem is.
Below we have listed the checklist for selecting the right vendor for your bottle testing lab:
  1. Check their factory license: Request them to show the video of the factory with the company name prominently displayed.
  2. Visit their factory and check their quality parameters: Take your samples and ask them to test them in front of you. If a physical visit is not possible, ask them to do it through Zoom, WhatsApp video or Google Meet.
  3. Try to contact the existing customers: Try to contact the existing customers over the phone or through a personal visit. This will give you an idea about whether the vendor you are selecting can provide you with high-quality testing equipment or not.
These are some of the top factors that one must consider while selecting the right lab testing instrument for your industry.
