Autoclaves with common head, external fittings, panel, motor, trolley etc. & interchangeable separate 2nos. vessel, heater & internal fittings (possible for 400ml, 700ml, 1Ltr. & 2Ltrs autoclaves). Amar does not promote this option as this is possible in autoclave having same diameter. Only the heights being different the minimum Stirrable volume is same hence it is advisable to go for only higher volume autoclave as changing the internal fittings like cooling coil & thermowell is not advisable regularly (if not refitted properly user many face leakage problem).Interchangeable any 2 autoclaves with common panel, motor & trolley. If space is the constraint, cost of panel, motor & trolley of one autoclave can be saved but the user loses the flexibility of using 2 autoclaves at a time. This option is possible for 50ml-5Ltrs., any two size autoclaves at a time.
