DYNTTS - Setting Up a Sample

The following steps should be followed, as a guide, to set up a sample in for use in the MINIDyn:

1. Prepare a relevant sized sample for your pedestal. This can be done by a number of ways i.e. by trimming back a slightly larger core sample, or by using a GDS Sample Preparation Kit.

Open

1. Before placing the moulded sample onto the pedestal and saturated porous disk, ensure to de-air the pore pressure and pore flush ports, as well as to fully saturate the porous disk.

1. Using a suction sleeve (a component of a typical sample preparation kit), pull the membrane over both ends. Apply suction through the hose to pull the membrane tight against the sides of the sleeve. Put two relevant sized o-rings over one end of the suction sleeve and then place this end first over the sample (already situated on the pedestal).

Open

1. Reduce suction on sleeve, roll each end of the membrane off the suction sleeve, as well as the two o-rings onto the pedestal as shown below.

1. Remove suction sleeve from around the sample and fold the

tail of the membrane up over the o-rings

1. Attach the top cap to the back pressure line and push water through the tube to ensure that it is thoroughly de-aired

1. With a three-piece mould, or something similar, around the sample – pull the top overhang of the membrane over the lip of the former and place two relevant sized o-rings over the top of this mould also

1. Place a fully saturated porous disk on-top of the sample and then the de-aired top cap on-top of this.

1. Pull the excess membrane over the top-cap, along with the two o-rings and then fold down the tail of the membrane over these o-rings also.

10. Remove the three piece mould and you should have a similarly prepared sample.
