Laboratory glassware - other

It is the marketplace category for glass labware that does not fall under a named glassware type, covering flasks, borosilicate pieces and glassware washers. It gathers the glass items a lab keeps on hand but that do not warrant their own category heading.

The word other signals that these listings are glassware without a dedicated type page of their own, so they are pooled together. A buyer finds borosilicate flasks, volumetric flasks, evaporating flasks and washer units grouped here rather than split across separate categories.

Each piece does a defined job set by its shape and glass: a volumetric flask holds an exact volume at a stated temperature, an evaporating flask mounts on a rotary evaporator to remove solvent under reduced pressure. Borosilicate glass handles heating and reagent contact because it tolerates thermal shock and resists most reagents.

The recurring forms are laboratory glassware, borosilicate glassware, borosilicate glass flasks, evaporating flasks and volumetric flasks, plus the laboratory glassware washer as equipment rather than glass. Borosilicate pieces make up the bulk because they survive heating and reagent exposure.

It carries the reagent handling, solution preparation and sample work behind most bench protocols, from preparing standard solutions in volumetric flasks to removing solvent in evaporating flasks. The same borosilicate flask may pass through genomics, proteomics, microbiology and immunoassay work over its life.

Start with the glass composition, because it fixes what the piece can do: borosilicate for heating, autoclaving and chilling, soda-lime for storage and room-temperature work only. For a volumetric flask, match the accuracy class to the work, with Class A meeting tighter tolerances than Class B.

Used glassware is sold in its current condition as it comes from the prior owner, while refurbished stock has been checked and reconditioned before listing. Both are listed below new pricing, and the individual listing states the condition and spec for each piece.

Prices range from EUR 1 to EUR 34.436, with the average at EUR 700. A single consumable flask sits near the bottom and a full glassware washer unit sits at the top, so the spread reflects two very different purchases inside one category.

The names that appear most often are Corning PYREX, Corning, Globe Scientific, Scilogex and the Various heading for unbranded stock. Corning PYREX and Corning cover the borosilicate vessels, while Globe Scientific and Scilogex cover general consumables and smaller instruments.

A warranty is often possible and is arranged in consultation for the specific listing. Check the listing itself, since terms vary by seller and by the condition of the piece.

Parts, including a matching ground-glass stopper, can be sourced via Questpair. This matters because a mismatched stopper leaks and a seized one can crack the neck of the vessel.

Borosilicate glass can serve for years because it resists thermal shock and most reagents, with the practical limit set by chips, star cracks and etching from harsh cleaning rather than age. A volumetric flask reaches the end of its useful life once its calibration mark or Class rating wears off and can no longer be trusted.

Used and refurbished pieces are listed at lower prices than new, which is where the affordable stock sits. The deciding factor is condition: inspect used glass for cracks, chips and legible calibration marks, and weigh the warranty, which is arranged in consultation per listing.

The category holds 574 listings from 17 verified suppliers and distributors across 8 countries. Each listing carries its own condition and spec, so comparison happens at the listing level.

Lead time and shipping depend on the individual seller and the piece, since stock spans 17 verified suppliers and distributors across 8 countries. The listing shows who holds the stock, and specialists respond within 1 hour if you need to confirm availability.

Volumetric flasks are calibrated to contain an exact volume at a stated temperature, so verify the calibration mark and Class rating are legible before relying on quantitative results. For cleaning, a laboratory glassware washer cleans and dries batches to a reproducible standard, which matters where residue ruins a result.

Borosilicate glassware and borosilicate glass flasks make up the bulk, chosen wherever heating or reagent contact is involved. Analytical chemists reach for volumetric flasks to prepare standards and dilutions, sample-prep and formulation benches reach for evaporating flasks on a rotary evaporator, and molecular biology and cell culture labs reach for the glassware washer where residue cannot be tolerated.

Corning PYREX and Corning are the borosilicate reference, so a model is easy to match against a datasheet and replacements are simple to find. The Various heading is the largest single entry and collects unbranded or mixed stock, which pushes entry prices down but makes a piece harder to compare spec for spec.

The bottom of the band is a single evaporating flask or a pack of borosilicate beakers, often unbranded stock under the Various heading. The top is a cabinet-scale laboratory glassware washer, a machine rather than a glass piece, which is why the price spans from EUR 1 to EUR 34.436.
