Calorimeter Printers
The Parr Calorimeter Printer is offered as a low cost accessory which can be attached directly to a 1261 calorimeter to produce a complete printed record of all essential data and results from each calorific test. It prints a clear record of all data on standard 4.5 inch wide paper in a 40-column format. Parr Instruments
Parr Electric Water Heater
For adiabatic calorimeter. Provides a convenient and compact source of hot water for adiabatic or isoperibol calorimeter operation in laboratories that do not have adequate hot water supply or where it is desired to operate independent of the existing system. Can be used for other needs requiring heated tap water to temperatures up to 80 degrees C. There is a relief valve on the heater for protection against overpressure and a strainer to keep scale and foreign matter out of the water[…] Parr Instruments
General Purpose Bomb Parr 4744
This is a 45 mL modification of the 23 mL, 4749 PTFE lined bomb for users who want additional capacity in this popular model. It is made with the same closure as the 23 mL bomb, using a similar thick-walled PTFE cup, 3-3/4 inches deep inside, with a broad flanged seal. Safety blow out protection is provided with a rupture disc that will release pressure through an opening in the cover. Its maximum temperature and pressure ratings, 250°C and 1800 psig, are the same as for the 4749[…] Parr Instruments
Benzoic Acid Calorific Standard, Parr
Calorific standard in powder or pellet form for standardizing all oxygen bomb calorimeters. Parr Instruments
General Purpose Bomb Parr 4745
This is the original acid digestion bomb introduced by Parr in 1969 to provide a PTFE lined metal bomb of simple design and minimum cost that can be used safely for routine sample preparation purposes. Its wide acceptance over the intervening years has proved it to be an excellent design for general digestion procedures in which temperatures and pressures are held below 150°C and 1200 psig. It can be used occasionally above 150°C, but at elevated temperatures it becomes[…] Parr Instruments
General Purpose Bomb Parr 4749
This is a 23 mL, general purpose acid digestion bomb, similar to the original 4745 model but modified for use at higher temperatures and pressures, and provided with safety blowout protection as well. Operating temperatures and pressures up to a maximum of 250°C and 1800 psig are permitted in this bomb using a thick-walled PTFE liner with a broad, flanged seal. The forces required to seal the liner are developed by tightening the bomb cap with a spanner while holding the bomb in a[…] Parr Instruments
