Technical Specifications

KM-P Technical Specifications

These are the current design specifications. Items marked "per configuration" depend on the sample and final proposal; the formal specification governs. CO2 consumption and cycle time depend on the sample and process window.

Engineering Features

Delicate Sample Protection and Safety

In-House Low-Temperature Fine-Control Valve
A patented team design for precise filling and depressurization under low-temperature, high-pressure and dry-ice-prone conditions.
Slow Filling and Sample Protection
Slow liquid-CO2 exchange reduces flow impact on micro/nano structures and aerogel pores.
Touchscreen Recipe Management
Default processes cover many samples, while recipe storage, editing and recall shorten method setup.
Three-layer Safety
Mechanical relief, electronic alarms and program interlocks cover the lid, over-temperature and over-pressure conditions.

Selection & Preparation

KM-P Selection Questions

Compare chamber sizes, operating ranges and applications →

What are the standard KM-P critical point dryer chamber sizes?

Standard chambers are 2.5 inches (about 100 mL) or 3.4 inches (about 186 mL). Sample cages, mesh plates and holders reduce the space available for samples.

Can water-containing samples go directly into the KM-P?

Usually, no. Keep samples immersed while replacing water with an intermediate solvent compatible with liquid CO2, then exchange that solvent for liquid CO2. Confirm the preparation route for each sample.

How do KM-P operating limits differ from maximum safety limits?

The published operating range is 0–1500 psi and 0–50 °C. Maximum safety limits are 2000 psi and 55 °C. Safety limits are not routine process setpoints.

Should I choose KM-P or KM-V for microscopy specimens and aerogels?

Evaluate KM-P for benchtop preparation and small samples, and KM-V for larger bulk samples or greater loading volume. Check sample dimensions, holders, solvents and target morphology, then confirm through testing.

Sample Testing

KM-P Sample Testing and Process Assessment

Provide the sample and target morphology. We run the complete exchange, critical-point crossing and controlled-depressurization process on the KM-P, then report the sample condition and microscopy results.
