Assembly

Slide the liner tube (plastic or Titanium) into the supporting cylinder from below and align the cut-outs. Ti liners should be fixed with a 5 mm hex wrench to avoid marks in the base plate.

Place the silicone disc with the hole on the Ti base cylinder (picture shows plastic version).

Place the PTFE (or Ti) drain disc on top and put a screen. Wrap Ti mesh screens with PTFE tape so the edges do not cut the filter paper.

Place a filter paper on top. 50 mm; 0.45 µm filters fit well. If you use Whatman #1 55 mm filter papers they have to be placed in the liner tube (54.8 mm).

Gently slide everything into the liner tube from below.

Align the drain hole with the cut-out.

Slide everything into the base plate, again making sure the cutouts and drain hole are aligned. The base plate is necessary to assure stability and keep the liner and support cylinder down.

Using the funnel put approximately 100 to 150 mL sample into the squeezer. Make sure the filter paper and screen stay in place.

Put the top PTFE disk with the seal lip showing downwards

and a perfectly round silicone seal disc.

Insert a plunger with plastic liner and put the whole assembly into the hydraulic press.

Turn the spindle down by hand.

Firmly insert a syringe with a disposable filter into the luer cone drain hole. Make sure the syringe plunger is mobile.

Set the valve to closed and start pumping with the handle. The hydraulic press has a maximum heave of 20 mm so you might have to open the valve and readjust the spindle.

If everything went right the syringe should start filling with pore water. From time to time make sure the syringe fits firmly. You may also pull on the plunger to make sure it does not block.

CAUTION: Always use the protective case, which is removed here for better view. The max. load is 20 tons. Usually you should not need more than a few tons. Do not use more than 5 tons if not absolutely necessary.
