  2. What is the best way to sterilize Heparin sodium salt?

    1 respuesta
    1. Although solutions may be autoclaved at 121 °C for 5 to 10 minutes, we generally recommend sterile filtration. This is because prolonged autoclaving may have an effect on its activity.

  4. How does the storage temperature relate to shipping conditions?

    1 respuesta
    1. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
