Critical point apparatus
Article No: 04365-00
Compact device for demonstrative, quantitative analysis of real gases as a function of pressure, temperature and volume. Observation of the transition from gaseous to liquid phase Recording of isotherms, isochores, isobars, vapor pressure curves Determination of critical data and coefficients of the Van der Waals equation of state Transparent, volume-calibrated, temperature-controlled measuring capillary made of special glass, on stainless steel pressure chamber Handwheel for pressure generation Inlet valve with pressure can connection Outlet valve for vacuum pump connection Demonstrative pressure gauge and transparent plastic cylinder with hose connection olives for temperature control of the measuring volume Measuring capillary: Measuring range 4 ml pressure-resistant up to 7.5 MPa at 60 °C Graduation 0.05 ml Pressure gauge: Measuring range 0 ... 50 bar (0 ... 5 MPa) Graduation 0.5 bar Temperature range 0 ... 55 °C Dimensions (mm) 335 × 340 × 670 Accessories Suitable gases: Pressure can sulphur hexaflouride (Tk = 45 °C, pk = 38 × 105 Pa) 41772-21 Pressure can ethane (Tk = 32 °C, pk = 49 × 105 Pa) 41772-09 Replacement material: Measuring capillary
