50 ml hydrothermal autoclave

The HNZXIB KH-50ML is a 50 ml high pressure digestion vessel built for laboratory sample preparation. It serves analysts who need a small reaction chamber for hydrothermal synthesis or pressure digestion workflows.

Sustained 220 °C and 3 Mpa operation

The reactor maintains a maximum temperature of 220 °C and a maximum pressure of 3 Mpa during extended heating cycles. Its PTFE lining resists corrosion and remains insoluble in almost all solvents, supporting long term stability without leakage.

Non magnetic stainless steel body with PTFE chamber

The outer shell uses Cr18Ni9Ti stainless steel while the inner chamber is 50 ml PTFE. A tightening screw design secures the lid and gasket for reliable sealing. Filling factor must stay below .8 and the lower gasket must sit with the raised side correctly positioned.

Questions about this item

How much heat does the 220 °C autoclave add to a lab running it all day?

The vessel reaches a maximum of 220 °C externally; the PTFE liner and stainless shell contain the heat, so ambient rise depends on your oven or heater choice.

What heater must I already own to run the 50 ml KH-50ML safely?

A programmable heater with controlled ramp rates is required; muffle furnaces are unsuitable because overshoot can melt the PTFE liner.

Will the 22 MPa pressure rating work with my existing 25 ml or 100 ml reactor racks?

The KH-50ML shares the same external stainless geometry as the 25 ml–500 ml series, so it fits standard multi-reactor oven shelves and racks.
