Los inyectores manuales tienen dos posiciones, 'Cargar' e 'Inyectar'. La posición de 'Cargar' permite cargar la muestra en el bucle de muestra o en la cámara de muestra. Normalmente se usa una jeringa para cargar la muestra en el inyector de muestra. Tras la carga, la rotación manual del inyector manual de la muestra a la posición 'Inyectar' permite el lavado de la muestra cargada en la columna.

These manually operated butterfly valves are made of stainless steel with viton seal.

Supplier: VACUUBRAND

These valves are compact air admittance valves with small flange. The VB valve is manually operated. On rotating the knurled screw cap the valve disc is lifted off the seating and air enters through the holes. The valve disc is rotatable. Therefore the valve seat seal is prevented against wear during opening and closing.

Supplier: UPCHURCH SCIENTIFIC

Designed to accurately split and control the low flow stream of a single incoming supply.

Supplier: UPCHURCH SCIENTIFIC

For fine control of fluid flow rates, these valves can reduce outgoing flow. These needle valves are perfect for use with peristaltic pump fluid transfer applications, mass spectrometry and fraction collection. They can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back pressure regulator.
