If you need the item quickly, before we run around like headless chickens, call the company to verify it's in stock and not on backorder. Finding another vendor and canceling the first order is to be avoided. Be sure to include your name on your order in the End User box. Oligo receipts have a separate bin. Wear the proper PPE, Eye glasses or face shield, thermal gloves, apron, closed shoes etc.
Propane is an explosive gas.
Do not use near flame or ignition source. The instrument grade propane we use does not have an odorant so extra caution must be used to prevent it escaping undetected into the lab. Liquid propane does not form this protective gaseous layer. This being the case it will burn you faster and more severely then liquid nitrogen. Always be sure to at least wear cloth gloves under your latex gloves when handling liquid propane.
