Due to a death in our organization we have temporarily changed our ordering procedures. We are now allowing phone in orders for in-stock items only, paid with a credit card. We are not currently accepting purchase orders. Existing orders will be processed. Thank you for your understanding.
Glassware and tools in laboratories and hospitals that are to be used in applications where contamination by foreign substances is undesirable and unacceptable are washed in ultrapure and even absolutely pure water. These items are usually cleaned by scouring and/or chemical and thermal sterilization. In some cases this equipment can still carry traces of chemical cleaners organic matter and even metal salts. These are usually removed by a final rinse in pure water.
