Bio-Chem Valve/Omnifit has helped the manufacturer of a DNA synthesisinstrument by providing custom-designed bottle caps for use with standard threadless reagent bottles. The manufacturer needed to transfer reagent from the bottles into the instrument, but because the reagent was depleted so quickly the empty bottles had to be rapidly exchanged tominimise downtime. The solution from Bio-Chem Valve/Omnifit was an engineered bottle cap with an inner PTFE core and an outer PEEK retainer. PEEK is rigid, durable and chemically resistant and eliminates the risk of the thread stripping with repeated use. An innovative lip on the inside of the retainer secures the rim of the threadless bottle andlocks it in place with a half rotation, leaving the bottle suspended securely from the cap. For ease of use the bottle caps can be panel mounted, securing the assembly so the operator can perform a quick, single-handed bottle changeover.
