Samples for moisture content tests should only be accepted if they are submitted in an intact moisture proof container from which as much air as possible has been excluded. Most customers submit their samples in 250 gauge polythene bags that are either tied or closed with elastic bands. Neither of these methods of sealing provides a proper seal, which could be accomplished using a Wagtech Projects heat-sealer. Where a heat sealer is not available it is recommended that the seed testing lab obtain a supply of heavy duty polyethylene bottles with screw top seals.
