Product Knowledge
Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
A desiccator is a sealed glass chamber that holds a dry atmosphere over a desiccant such as silica gel. Labs use it to dry samples and to stop dried or hygroscopic materials from taking up moisture from the air. A perforated plate holds the samples above the desiccant, and a greased ground-glass flange seals the heavy lid.
Vacuum desiccators add a stopcock in the lid so the chamber can be evacuated, speeding drying for damp or heat-sensitive samples.
Desiccators are used to dry samples over desiccant, store hygroscopic chemicals and materials, and cool oven-dried crucibles and weighing bottles before weighing. They support gravimetric and moisture work in pharmaceutical, food, analytical and QC labs, and dry storage of components in electronics and materials labs. Vacuum versions are chosen for samples that can’t be oven-dried or that hold moisture stubbornly.
The chamber is heavy-wall borosilicate 3.3 glass with a wide ground flange and a matching lid that seals with a thin film of desiccator grease. A knob on the lid makes it easy to lift, and a removable perforated porcelain plate sits above the desiccant well. Vacuum versions have a lid stopcock, often with a PTFE key, for evacuation and controlled venting. Sizes are given by the nominal plate diameter.
Keep fresh desiccant in the well and a thin, even film of grease on the flange. Slide the lid sideways to open or close it rather than lifting it straight off. Let hot samples cool briefly before sealing them in. Evacuate only desiccators made for vacuum service, and use a safety cage or shield, since an evacuated glass chamber can implode if it is flawed. Vent slowly through the stopcock before opening.
We form the chamber and lid in heavy-wall borosilicate 3.3, grind the flanges to a matched sealing fit and anneal them carefully, which matters for thick glass used under vacuum. The porcelain plate is supplied as a separate part. Options include standard or vacuum lids, glass or PTFE stopcocks, amber glass, spare plates and spare lids. Tell us your plate size and vacuum needs and we’ll quote a complete set.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
