Sample Preparation


Any of the magnetic Hampton bases ( are suitable for use with the ACTOR Robot. Plastic or screw cap bases can NOT be used with the automounter!

Pins and Pin Lengths

Any pin and loop combination are suitable for the automounter. The “standard” size is an 18mm pin length mounted on a magnetic base for a base to loop distance of 21-23mm. It is possible to use different lengths, but it is essential that length is consistent across samples. Otherwise it is likely the sample will be out of the cold-stream after mounting. Note that there is a 4mm “window” in the length before the samples are out of the cold-stream. The following image demonstrates measurements on a Hampton pin.
