Expiration Policy: An unopened bottle stored according to SEASTAR™’s product integrity guidelines1, within the expiry period, is guaranteed to maintain the maximum specification of the product. SEASTAR™’s product expiration date is included on its labels and certifications. Do not use this product once the expiration date is reached. The expiration date defines both the end of the product shelf life2 and its certification. The expiration date is conditional; products must be stored and transported according to SEASTAR™’s Product Integrity Guidelines1.

Plastic bottles should be inspected regularly, specifically HDPE bottles, for any evidence of change to the plastic bottle’s ability to deform. The ability to deform is defined by its ductility/plasticity/malleability/embrittlement, or hardening/compressibility. If any change is noticed, carefully and safely transfer or dispose of the product according to your safe handling practices and procedures. Any product disposal must be done according to applicable regulations governing the disposal of the hazardous product.

    2. BASELINE products should be used in a minimum of Class 100 or ISO 5 clean room conditions.
    3. Once the product has been opened and is being used in the lab, the integrity of the product can be maintained by following standard trace metal clean room contamination control procedures.

2Shelf life: A product shelf life is defined as the valid period unopened product can be used, providing it has been transported and stored according to the guidelines above.

3HDPE: The HDPE bottles used for SEASTAR™ Instrument Quality (IQ) products, specifically IQ Nitric Acid (S010101), IQ Perchloric Acid (S010201), IQ Sulphuric Acid (S010301), IQ Hydrochloric Acid (S010401), IQ Acetic Acid (S010601), and IQ Ammonia Solution (S010701) use a specially manufactured High Density Polyethylene resin designed and tested to be resistant to nitric acid. The resin has been chemically modified before being molded to form the bottle.
