CERTAN BOTTLES

Long term storage of standard solutions has presents many problems. Sealed glass ampoules provide secure long term storage, but once opened, are unsuitable for further storage, while screw capped bottles invariably allow solvent losses, and are attended with the risk of contamination from the cap and sealing wad. CERTAN capillary bottles from LGC Promochem combine the advantages of a flame sealed glass ampoule with the flexibility of a screw capped bottle and septum vial. CERTAN capillary bottles provide the following advantages:

● Evaporative losses virtually eliminated ● Almost impossible to spill ● Minimised risk of contamination ● Easy filling and removal of aliquots with a normal GC syringe ● Proven usability from -30°C to +50°C CERTAN capillary bottles are ideal for the storage of solutions removed from glass ampoules, working stock and standard solutions, volatile compounds or even samples for archive. They are available in 1.5mL, 4.5mL and 10mL capacities. Please contact us for prices or to ask for the CERTAN Capilliary Bottle brochure. A graph comparing the evaporative weight loss of solvents from an uncapped CERTAN capillary bottle against other commonly-used containers is available for viewing with Adobe Acrobat Reader.
