You are viewing a general purpose acid digestion bomb from the Parr Instrument Company. This vessel is of the original design introduced by Parr in 1969, model #4745, a design that, due to its popularity and simplicity, continues to be manufactured today. It can be used for sample preparation at temperatures below 150 degrees Celsius and pressures under 1200 psig. Model 4745 does not include a rupture disc but the bottom plate of the vessel is designed to shear out, and prevent a more dangerous explosion, at pressures exceeding 7000 psig. There is more information on the Parr website: http://www.parrinst.com/products/sample-preparation/acid-digestion/general-purpose-acid-digestion-vessel-model-4745-23-ml/ This is a used item in good, and as far as I can tell, working condition. I do not know the age of the vessel but it is probably at least 15 years old. It is made of solid brass with some kind of plating (Parr now makes the vessels out of stainless steel). The plating is worn in places (see pictures) but the vessel seals tightly. The closure is spring loaded to keep the PTFE cup sealed at high temperature and pressure. This auction also includes the PTFE sample cup with 23 mL capacity. The cup is in very good condition. It has a number carved on its bottom and cap. I am selling both the digestion vessel and the cup "as is" because I have no way to test them. I have several of these in similar condition so the listing pictures may not be of the exact item you receive. If you would like to see pictures of the exact item, please contact me. A new model #4745 acid digestion vessel is listed on Fisher Scientific for $603.95 and the 23 mL PTFE cup sells for $149.29. Thank you for looking. If you have any questions, please feel free to ask. If you win the auction, I will ship the item within two business days of my receipt of your payment.
