Ideal for capping and recapping 12 – 13mm tubes, Deltalab’s Mauve Polyethylene Caps for 12 – 13mm Tubes with Flange Plug present significant advantages over other flange caps existing on the market, which are:
- A larger size, providing a larger surface for finger rest
- Flanges have a large size than on other caps. More space between each flange increases the cap’s sealing qualities
- A small internal cavity designed to prevent possible drop spillage
- A raised top for easy-on, easy-off use and to avoid cap deformation from repeated removal
- A ribbed surface.
