SLPM
The standard litre per minute (SLPM, also SLM; written NL/min when the reference is "normal" conditions) is the gas flow that would occupy one litre per minute at standard reference conditions. 1 SLPM = 1000 sccm.
Symbol: SLPM
Quantity: volumetric flow rate (volume per unit time)
SI relation: 1 SLPM = 0.00001666666666667 m³/s (exact)
Derivation: 1 SLPM = 10⁻³ m³ ÷ 60 s, measured at standard reference conditions
Exact: yes, by definition
Reference conditions. Standard flow: volume the gas would occupy at the standard reference conditions (default 0 °C, 101.325 kPa). Converting to actual flow needs the actual temperature and pressure.
Typical uses
- Mass flow meters and controllers
- Pneumatic component flow ratings
- Medical and laboratory gas supply
