ptfe filter vents for venting technologies












Customers Experience

A world producer and breeder of Phalaenopsis in Taiwan has made use of of our PTFE for many years mirroring the growth of the number one orchid plant in the world.

Dutch cut flower nursery decided to adopt our AMD venting system many years ago as it was the best and most economic route for venting. They were able to eliminate many of their original venting problems with our help and advice.

Belgium biotechnology and seed company company with international plant breeding program used or AMD vents for bulking up their breeding lines.

We were one of the Worlds largest producer of flasks of Paphiopedilums in UK and USA as TQPL. Plants bred and sold by Ratcliffe Orchids. We use to produce all their flask production for many years before they contracted their business.

Transporter of Orchid flasks worldwide found that exported plants travelled perfectly with our venting system. Eliminating problems that used to be associated with such transport.
























Plants and PTFE venting

Growing plants in a laboratory environment by tissue culture, micropropagation or aseptic germination along with the production of in-vitro cell lines are all possible with our venting discs.

The use of our Adhesive Microfiltration discs (AMD) is very easy and simple to incorporate into laboratory plant production. It replaced traditional venting with cotton wool and is well adaptable to modern plastic ware or glass jars with lids of plastic or metal. They can also be used with traditional rubber bungs with drilled holes.

AMD are full autoclavable. Discs are simply applied over a venting hole drilled in the lids and then autoclaved as per normal. Autoclaving allows all the internal mircrofibrils to be come aseptic to ensure there is no internal contamination. We supply information sheets to help with your autoclaving process and using our discs. Microwave sterilization cannot be used with our multi layered discs.

PTFE vents will allow elevated in-flask humidity to be maintained This will ensuring greater levels of stomata opening and higher volume gas exchange resulting in better and quicker plant growth. This is only possible with a hydrophobic venting system.

PTFE venting retains higher water vapour pressures and atmospheric moisture in-vitro than conventional venting. High levels of air exchange and photo transpiration is possible without the detrimental dehydration associated with conventional venting. Put simply - your plants will grow quicker with the right venting system such as an Adhesive Microfiltration Disc.

The flow and exchange of air provides another source of carbon for plant growth in additional to the sugars in the media. Research reveals that in vented cultures the plants significantly rely on this traditional source of carbon for improved growth.

This is the main reason why plants grow better with an AMD venting system. It mirrors the effect of increasing humidity in a glasshouse where stress free plants grow at their fastest. Depletion or low levels of carbon dioxide gas can also be overcome, while ethylene and other detrimental gasses will be able to diffuse out.

It has also been reported in plant tissue culture work that plants from vented cultures are more easily prepared for transfer out of culture. A plant from a vented system is already partly relying on traditional photosynthesis pathways with functional stomata and gas exchange.

We have proof that this is indeed the case from plants we have produced and in collaboration with nurseries in UK, USA and Europe. Plant losses on establishment out of flask can be almost totally eliminated with our venting systems.

Hyperhydracity or vitrification problems can be eliminated or reduced by improving the air and gas exchanges for those plants that are susceptible..

AMD's can be used to reduce the humidity in the culture vessel. This can be a problem where culture are exposed to large temperature fluctuations. Better monitoring of the growth rooms, cooling systems and diurnal fluctuations should also be looked at in connection with the culture vessel venting system.
