Purchasing Questions

When purchasing new or used capital equipment, there are some questions that need answering before you will be able to get a quote that you can count on. Over the years, we have found that there are several basic questions that we ask all potential clients whether they have been looking already or just starting their search for equipment. These questions are as follows:

  • Autoclave
  • Oven
  • What size autoclave do you need? (Please provide inside diameter and length.)
  • What operating temperature and pressure do you require?
  • What is the maximum allowable pressure that you need?
  • What is the maximum allowable temperature that you need?
  • Do you need vacuum lines? If so, how many do you want?
  • Do you require controllable vacuum?
  • How many thermocouples will you need?
  • Do you need a cooling system?
  • What heating / cooling rate do you require?
  • Do you want to heat with gas or electricity?
  • Are you looking for strictly a used autoclave? Note: In some cases a new unit is less expensive!
