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 dropping bottle keeps a reagent and its dispenser together as one unit. The glass pipette is ground into a matching joint in the bottle neck and topped with a rubber bulb, so the user lifts out the pipette, dispenses a few drops and puts it back, with no separate dropper to find or mix up.
It is the classic container for indicators, stains and other drop reagents used constantly at the bench.
Labs use dropping bottles for titration indicators, microscopy and histology stains, drop reagents, and clinical, diagnostic and QC bench reagents. Teaching labs use them in student reagent sets, and test-kit makers use them for field kits where a reagent must be dispensed by the drop. Amber bottles protect light-sensitive indicators and stains on open shelves, and matched sets in one size keep a bench rack neat and easy to label.
The bottle is borosilicate or laboratory soda-lime glass with a ground-glass neck joint matched to a ground-in glass pipette. A rubber bulb sits on top of the pipette, and the ground joint closes the bottle when the pipette is in place. Clear and amber glass are available, and a marking spot on the body takes reagent labels. Capacities run from 10 ml for small indicator sets up to 125 ml.
Keep each pipette with its own bottle, as the joint is ground as a matched pair, and dedicate each bottle to one reagent to avoid cross-contamination. Some solvents and strong reagents attack natural rubber; for these, ask us for a bulb in a more resistant material. Use amber bottles for light-sensitive indicators and stains, and rinse the pipette when changing reagents.
We form the bottles and pipettes, grind the neck joint and pipette shank to a matched fit, anneal them and fit the bulbs. Amber color comes from the glass batch. Joint fit and pipette matching are the key production checks. Options include clear or amber glass, latex or synthetic bulbs, printed reagent names or logos, and kit packing in counts.

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.
