Filtration of Wine Samples with Midicaps Capsules

When small volumes of wine need to be filtered for their presentation and tasting, Midicaps^® capsules simplify your filtration in complete safety while respecting your wines. Our winemakers recommend to filter your wines with the same filter material (polypropylene, fiberglass) on your bottling lines using ready-to-use filtration capsules.

Sartorius provides a 5 liter stainless steel vessel for the filtration of wine samples that can also be used for the measurement of the clogging index and Vmax.

2 in 1!

Equipped as standard with a support disc of 25 mm in diameter to measure the clogging index and Vmax.
Triclamp connector for mounting a capsule filter and filtering wine samples.

Embossed on the capsule : user instructions and direction of filtration

Ease of Use

Available with different connections: Triclamp or hose bard
Sterilized by autoclaving or hot water

Quality

Purge and sanitary air vent for strict hygiene
Midicaps are validated according to FDA recommendations

Filtration of samples for making a successful wine tasting!

Which filter material and pore size should I choose?

The filter material of the Midicaps capsules are the same as those used on the bottling production lines (polypropylene, fiberglass) but with filter areas 10 times smaller. Depending on filtration objectives, multiple pore sizes are available:

Brightness of the wine : 0.65 μm or 1 μm with fiberglass or polypropylene filter
Clarification and retention of particles : from 20 μm to 0.65 μm with polypropylene filter

What filtration area should I choose?

Midicaps filtration capsules are available with filter areas from 500 cm2 to 0.45 m². The filter areas most frequently chosen are 0.1 or 0.2 m².

What connection should I choose to filter a small batch of wine?

Midicaps capsules are available with the following inlet / outlet connections (**):

SS = 11/2” Tri-Clamp Sanitary connectors
SO = Triclamp-1” Single stepped hose barb connectors
OO = 1” Single stepped hose barb connections

Thus it is possible to connect directly to a wine tank in the cellar or a small tank in the laboratory (see 5 liter tank).

** Inlet/ Outlet Connections: SS = 11/2” Tri-Clamp Sanitary connectors or SO = Triclamp-1” Single stepped hose barb connectors or OO = 1” Single stepped hose barb connection

Can I reuse the capsules after filtering a small batch of wine?

After filtration, Midicaps can be rinsed with cold and then hot water (regeneration). Finally, they must be sterilized/dried before storage for later use. Contact us for advice on the regeneration and preservation of capsules.
