I've purchased about 100 of these and found as much as 10% are improperly sealed. However, I don't feel it's a cheap product. The 90% are properly crimped and perfect, with good rubber seals and proper caps - they simply need to train their staff to properly crimp the aluminum caps, and proper QA to verify quality prior to shipment.
In addition to the vials volume (1ml, 2ml, 4ml, ), they are differences in vials type (screw, crimp, crimp or snap, shell), material (clear glass, amber glass, polypropylene), dimensions (12x32mm, 15x45mm, ), diameter (8mm, 9mm, 10mm, 11mm, ), just select all these parameters to determine the part number for your specific needs.
Crimp top vials, which require an 11mm seal, are available in a variety of styles. These vials have a solid glass finish and are available with a 4.6 or 6.0mm ID opening. The larger opening increases the target area for needle penetration.
I specifically purchased this product because of the top that is displayed in the listing. I purchased these vials with that top from a local retailer (almost $2.00 per) and they were top quality. Unfortunately, the tops which arrived with the vials I bought here are different. They are not as good.
