Plant Press A3 Premium

Plant Press A3 Premium

from $125.00

I individually hand build these Premium A3 presses using high quality, zero formaldehyde, Australian made 6.5mm Hoop Pine (Araucaria cunninghamii) plywood. The frame is constructed of FSC Tasmanian Oak and Plantation Pine.

The basic model is finish sanded, unsealed and has a glued frame, while the top model is built for maximum stability. It is constructed with 24 x 4g brass plated screws, Gorilla glue® , finish routed and sanded as well as being sealed with a single coat of Intergrain® marine grade, water-based clear finish to provide moisture and warp resistance. Both the basic and top models are built with Hoop Pine plywood.

The generous Jute compression straps and poly snap buckles allow for a decent stack of plant material, while the corrugated inserts assist with drying. This plant specimen press is designed for A3 paper and comes with a pad of 40 paper sheets and 8 repurposed corrugated cardboard sheets to get you started on your plant voucher collection or mini herbarium.

This Premium A3 size press has that little extra going for it being constructed of exterior grade, Australian made Hoop Pine plywood with substantially thicker outer ply layers .

It is small enough to take into the field with you but still big enough to cover a large variety of plant morphologies. Some of the bigger leaf and stem types might not be suitable and require a different and special approach. Think banana for instance.

It is best to press your plant specimen shortly after collecting it, before wilting begins.

Your specimens should be carefully laid out on the drying paper and their shape gently manipulated into a flat but representative appearance. Flowers should be spread out with the petals carefully arranged, and out-hanging leaves should be removed. Cut at the leaf blade if possible to retain the leaf arrangement. The same approach may be needed where many shoots make the specimen too bushy to flatten but these can be cut back right to the stem. If collecting several specimens, it can be good to attach a tag with information such as location and date, to the specimen. Place another sheet of drying paper on top of the specimen. The corrugated paper and the cardboard sheets help air circulate and can be placed at intervals as you add more specimens. Juicy specimens will require more frequent interleaving of the corrugated paper and cardboard to help both drying and flattening. Moisture and mould are the hazards when creating good voucher specimens. Original plant moisture content and ambient humidity will affect drying success, so how often you change the drying paper will depend on these variables but generally a couple of paper changes and two weeks pressing should be adequate to obtain a good specimen.
