Liquid flow cell

raytest flow cells for RAMONA Star designed for liquid scintillation flow monitoring are made of stainless steel holder, teflontubing and PFTE seals. Virtually all volumes between 5 µl and 1000µl can be made to the customers requirement without extra charge.

After insertion the individual cell information is automatically read from a built in microchip including :

cell number and volume
efficiency using 50 % Monofluor mixed to eluate of 25% isopropanol and 25% H2O
tested pressure resistance

Solid flow cell

Many different scintillator materials are available to provide the user with a range of possibilities for the measurement of radioactively labelled compounds.

raytest provide also flow cell with many various volume and particle size to offer the maximum sensitivity and efficiency.

Smaller solid scintillator particle enable :

less self absorption of beta radiation
more absorption of beta radiation in solid scintillator
higher efficiency
more sensitivity

Smaller solid scintillator particles increase back pressure of flow cell. Please check pressure resistance of detectors upstream. Solid scintillator flow cells avoid an expensive liquid scintillator consumption, a high volume radioactive liquid waste and a reduction of waste disposal cost.
