Description
Product Overview
The EISCO Crystallizing Dish offers a 300ml working volume within a compact 2‑inch tall, 3.9‑inch diameter form factor, making it an excellent choice for space‑constrained workstations. Constructed from premium Borosilicate 3.3 glass, the dish provides exceptional optical clarity, allowing users to monitor crystal growth or solution changes without distortion. Its flat bottom ensures stable placement on heating plates, while the integrated spout enables controlled decanting of liquids, reducing waste and improving experimental precision.
Durability is a hallmark of this dish; the borosilicate composition tolerates rapid temperature fluctuations, direct flame exposure, and prolonged heating up to 350 °C without cracking. Chemical resistance is equally impressive, with the glass resisting corrosion from acids, bases, and organic solvents, which means the dish can be reused across a broad spectrum of analytical protocols without degradation. This resilience translates into lower long‑term costs for laboratories and educational institutions.
The thoughtfully engineered spout features a smooth, tapered lip that minimizes splashing while allowing accurate transfer of liquids into receiving vessels. Coupled with the flat bottom, the design reduces the risk of sample loss during evaporation or crystallization steps. The dish’s dimensions also align with standard laboratory racks and storage cabinets, facilitating seamless integration into existing workflows.
Beyond its laboratory credentials, the dish is compatible with common sterilization methods, including autoclaving, dry heat ovens, and chemical disinfectants. This flexibility ensures that the dish can be quickly prepared for successive experiments, maintaining a sterile environment essential for reproducible results. The robust glass also withstands mechanical handling, making it suitable for transport between workstations or field sites.
While engineered for scientific use, the dish’s clear glass and ergonomic shape make it equally valuable in culinary and craft applications. Home chefs can employ it for precise sauce reduction, while hobbyists may use it for resin casting or small‑scale crystal growing projects. Its versatility bridges the gap between professional and personal use, delivering consistent performance across diverse contexts.
Usage
In professional laboratories, the dish excels during evaporation processes, where its flat bottom provides uniform heat distribution, and the spout enables effortless removal of concentrated residues. Researchers conducting crystallization studies benefit from the clear glass, which allows real‑time observation of crystal morphology without disturbing the sample. The dish’s heat tolerance also supports reflux setups and gentle drying of heat‑sensitive compounds.
Educational settings find the dish indispensable for hands‑on demonstrations. Chemistry teachers can illustrate concepts such as solubility, supersaturation, and crystal nucleation, while the spout simplifies safe disposal of waste solutions. The dish’s durability ensures it survives the rigors of classroom use, including frequent handling by students of varying skill levels.
For home science enthusiasts, the dish provides a reliable platform for hobbyist experiments, from growing quartz crystals to testing the effects of temperature on solubility. Its modest size fits comfortably on kitchen countertops, and the borosilicate glass resists staining from pigments or dyes, preserving visual clarity for successive projects.
Artists and crafters appreciate the dish for resin casting, where the flat bottom creates an even base for molds, and the spout allows precise pouring of liquid media. The glass’s resistance to solvents ensures that harsh cleaning agents can be used without compromising the dish’s integrity, extending its lifespan in creative workshops.
Why Choose Us
EISCO has built a reputation for delivering industrial‑grade glassware that meets stringent quality standards. Each crystallizing dish undergoes rigorous inspection for dimensional accuracy, surface defects, and glass integrity, guaranteeing that every unit performs reliably out of the box. This commitment to quality reduces the likelihood of unexpected breakage, protecting both user safety and experimental outcomes.
The use of Borosilicate 3.3 glass sets this dish apart from standard soda‑lime alternatives. Borosilicate’s low thermal expansion coefficient minimizes stress during rapid heating or cooling cycles, while its high resistance to chemical attack preserves the dish’s clarity and structural strength over repeated use. This material choice is especially valuable for applications involving aggressive reagents or high‑temperature processes.
Design features such as the flat bottom and precision‑engineered spout are the result of extensive user feedback and ergonomic analysis. The flat bottom eliminates wobble on heating plates, ensuring consistent temperature exposure across the entire solution. Meanwhile, the spout’s smooth interior reduces adhesion of viscous liquids, allowing clean, controlled transfers that enhance reproducibility.
EISCO backs each product with responsive customer support and a clear warranty policy. Should any issue arise, users can rely on knowledgeable technical staff to provide troubleshooting guidance, replacement parts, or product exchanges. This after‑sales service underscores the brand’s confidence in the durability and performance of its glassware.

FAQ
Can this dish be used on an open flame?
Yes. The Borosilicate 3.3 glass composition is engineered to withstand direct exposure to open flames and rapid temperature changes. Users can safely place the dish over Bunsen burners or other flame sources without fear of cracking, provided the glass is not subjected to sudden thermal shock such as immediate immersion in cold water.
Is the dish compatible with autoclave sterilization?
Absolutely. The dish can be autoclaved at standard cycles (121 °C, 15 psi) for up to 30 minutes without degradation. The high‑temperature tolerance of the borosilicate material ensures that repeated autoclave cycles will not compromise the dish’s structural integrity or optical clarity.
What types of chemicals can the dish safely hold?
The dish resists a wide range of acids, bases, and organic solvents, including hydrochloric acid, sodium hydroxide, ethanol, and acetone. While it offers excellent chemical durability, users should avoid prolonged exposure to hydrofluoric acid, which can etch borosilicate glass. For most routine laboratory reagents, the dish provides a safe, inert container.
How should I clean the dish after use?
Cleaning is straightforward: rinse the dish with warm water, then use a mild laboratory detergent or solvent appropriate for the residues present. For stubborn deposits, a gentle scrub with a non‑abrasive brush is recommended. After cleaning, the dish can be rinsed again and either air‑dry or placed in a drying oven. Autoclaving after cleaning further ensures sterility for subsequent experiments.
Is the spout designed for precise measurement?
The spout’s tapered geometry facilitates controlled pouring, but it is not calibrated for volumetric measurement. For precise volume determination, users should employ separate measuring devices such as graduated cylinders or pipettes. The spout’s primary advantage lies in minimizing splatter and allowing smooth transfer of liquids from the dish to other containers.
