Pierre-Benn de Villiers2020-10-13T22:29:39+10:00The Flexcubes come in the following nominal volumes: 1kl/10HL/265Gal, 1.5kl/15HL/397Gal and 2kl/20HL/530Gal.
Why is the word “nominal” used when describing the size (volume) of a Flexcube?
Pierre-Benn de Villiers2020-10-13T22:30:12+10:00The walls are flexible, so expand and contract (slightly but significantly) when empty or full, so the dry volume will be smaller than the wet volume. So nominal means "approximate". The Flexcube holds something like 20-30L more volume than when it is empty.
How many Flexcubes can be safely stacked on top of each other when full?
Pierre-Benn de Villiers2020-10-13T22:30:49+10:00Up to 4,000L/40 hl/1,060gal worth. That is equivalent to: 4x1,000 litre Flexcubes or 2x2,000 litre Flexcubes or 2x1,500 litre Flexcubes + 1x1,000 litre Flexcube.
Is Bisphenol A (BPA) associated with Flexcubes?
Pierre-Benn de Villiers2021-08-11T13:24:03+10:00Flexcubes are BPA free. BPA has no role in the manufacture of any components of a Flexcube, so Flexcubes are free of BPA. A BPA free statement can be downloaded here.
Are Phthalates associated with Flexcubes?
Pierre-Benn de Villiers2021-08-11T13:30:12+10:00No. This has been verified in laboratories both sensorily and by analysis and in repeated analytical tests the company has conducted. A Phthalate-free statement can be downloaded here.
Can I use a Flexcube for white wine after using it for red wine?
Pierre-Benn de Villiers2020-10-13T22:33:12+10:00Yes. Just clean your Flexcube with caustic soda to de-colorise the polymer.
Does the polymer in Flexcubes scalp?
Pierre-Benn de Villiers2020-10-13T22:34:13+10:00While all polymers scalp to some degree, tests have shown that the scalping of the polymer used in the Flexcube is sensorially insignificant and is much the same as the polymer disc in a metal screw-capped wine bottle.
Does the polymer in Flexcubes migrate?
Pierre-Benn de Villiers2020-10-13T22:34:51+10:00Swiss laboratory (CIBA) reported migration according to EU migration standards is within safe levels. Sensory experience; in 10 years of Flexcube use throughout the globe there has been ZERO cases of 'plastic taint'. Regular HPLC / GC analysis of our polymers through accredited laboratories continually monitors this.
Shall I use hot water to clean a Flexcube?
Pierre-Benn de Villiers2020-10-13T22:35:24+10:00No. Hot water will distort the polymer and should never be used. Always clean your Flexcube with cold water and a 2% solution of caustic soda (sodium hydroxide) or similar.
