All GGA Standards are well-packaged and safely stored in sterile plastic vials with a screw-off-cap closure for convenience.
We also offer custom standard requests to reduce workload and increase laboratory performance efficiency. Our reference materials are available in 1mL ampules in two 0.6mL ampules to increase your shelf life at no additional cost.
