Vertical Autoclaves Manufacturer,Supplier and Exporter in India
Product Code : EL-A-2276
Jlab Export is a leading Vertical Autoclaves Manufacturer,and suppliers in India
These top-loading autoclaves heat water electrically and sterilise the load in saturated steam at a pressure set between 10 and 20 psi. The boiler is stainless steel inside a double wall, and the lid is clamped down with wing nuts onto a jointless neoprene gasket. Six chamber sizes run from 250 x 450 mm to 550 x 750 mm, with heaters of 1.5 to 5.0 kW.

Microbiology Practicals with the Autoclave
A first-year practical is making and sterilising nutrient broth. Students fill tubes, plug them with Non Absorbent Cotton Wool, stand them in a basket and run them in the autoclave. One tube is kept back unopened and incubated with the class set to show that the run worked.
Next session, the cooled broth is inoculated with a flamed Inoculating Loop Nichrome Wire, and the uninoculated control should stay clear. Teachers can also point out the pressure gauge, the air/steam release cock and the spring-loaded safety valve, and explain what each does during a run.
Frequently Asked Questions
How should the wing nuts be tightened?
Do them up in opposite pairs, a little at a time, as you would a car wheel. The lid then comes down evenly on the neoprene gasket. Tightening one side fully first tilts the lid, and steam escapes from the gap on the far side.
What does the 10 to 20 psi range mean for a run?
It is the steam pressure the chamber can be worked at, and steam gets hotter as pressure rises. Your lab method gives the pressure and holding time for each load. The safety valve can be set anywhere in the same range and works to within ±3 psi.
Which chamber size and heater load do I need?
Choose by the biggest load you sterilise in one run. Heater loads rise from 1.5 kW on the 250 x 450 mm chamber to 5.0 kW on the 550 x 750 mm one. The larger sizes need a single-phase socket and wiring rated for their load.
What do the radial lock and pedal lift options do?
A radial lock clamps the lid with one handle that moves all its locking arms together, so there are no separate wing nuts to turn. A pedal lift raises the heavy lid with a foot pedal, leaving both hands free to load the basket.
Why does the pressure keep rising and falling during a run?
Look first for steam escaping at the lid, the release cock or the safety valve, since any leak bleeds pressure away. An unevenly tightened lid is a common cause. If the heater trips the supply or switches off on its own, have the wiring and heater checked before the next run.
