Frequently Asked Questions
Which tube diameters does this cap fit?
The 118115 L universal cap is designed to fit most 12 mm, 13 mm, and 16 mm outer-diameter tubes, covering common clinical and general-purpose tube formats from a single SKU.
Are these caps sterile?
No. These caps ship non-sterile and are intended for general specimen containment, recapping, and storage rather than aseptic culture work.
How many caps are in a pack?
Each pack contains 1000 caps, priced at $57.80 per pack. Tiered pricing is available for institutional and grant-funded volume orders.
What solvents should be avoided with these caps?
Polyethylene caps perform well with aqueous buffers, dilute bases, and alcohols but resist aromatic and chlorinated solvents poorly. Avoid prolonged contact with those solvent classes.
