This product is no longer in stock
13mm vial stoppers are for serum vials with a 7mm diameter hole opening and 13mm outer rim-to-rim diameter. This size is commonly required for smaller tubing shaped serum vials (2mL and 3mL vials). Some larger vials will also require a 13mm vial stopper (such as our 10ml insulin vial). Extra silicone treatment facilitates easier insertion into the vial opening.
These stoppers are NOT sterile. Appropriate washing, rinsing and sterilization must be performed by the customer or end user to meet industry specific standards as deemed necessary.
