Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
Specimen jars are the vessels of the wet collection: biological specimens preserved in a fixative such as formalin or alcohol for study and display. A tall, clear cylindrical jar shows a whole specimen well and seals tightly enough to keep the fixative from evaporating over years of storage.
Glass is the standard material here for its clarity and its resistance to fixatives, which degrade many plastics over time.
Cylindrical specimen jars are used to preserve and display biological specimens in teaching collections, anatomy and pathology departments, natural history museums, zoological and botanical collections, veterinary schools and research wet collections. Smaller sizes hold dissection and teaching specimens; larger jars display whole organs or animals. The same jars also suit long-term storage of tissue, insect and field samples in alcohol.
Each jar is a tall, straight-sided cylinder in borosilicate or laboratory soda-lime glass, chosen for high clarity and even wall thickness so specimens are seen without distortion. Closures are either a ground-glass lid on a wide ground joint or a polypropylene screw cap with a PTFE liner on a GL thread, both selected to hold in fixative vapor over long storage.
Fill and seal jars in a ventilated area, as formalin and other fixatives are hazardous. A ground-glass lid seals best with a thin bead of a suitable sealant or grease; screw caps should have a liner that resists the fixative you use. Keep ground lids with their own jars, label each jar clearly, and check fixative levels periodically during long-term storage.
We form the jars in high-clarity glass and anneal them. Ground-lid versions have the joint and lid precision-ground to a matched fit; screw versions have a GL thread finished to profile. Clarity, seal fit and lid matching are the key checks. We can supply custom heights and diameters, square or rectangular display jars, printed labels and matched lid sets. Send us your specimen dimensions and we’ll suggest a jar size.
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.
