Conduct perfectly stable specific gravity and sedimentation testing with Heathrow Scientific Borosilicate Glass Hydrometer Jars (21000 Series). Designed specifically for housing hydrometers during liquid density readings, these heavy-duty glass cylinders feature an ultra-flat, enlarged base to prevent accidental tipping or spilling on the laboratory bench. Constructed from premium borosilicate glass, they provide excellent chemical resistance and complete optical clarity so users can easily read the hydrometer meniscus.
The 21000 Series is fully autoclavable, ensuring critical sterility can be maintained between testing different sample batches. They are available in a comprehensive range of capacities from 100 mL up to 1000 mL to accommodate virtually any standard hydrometer length. For advanced sedimentation testing, select 1000 mL models feature a precise 1000 mL graduation mark fired directly into the glass.
Features & Benefits
- Premium Borosilicate Glass: Withstands rigorous temperature cycling and exposure to harsh industrial chemicals.
- Enlarged Base: A wide, flat bottom provides maximum vertical stability even when accommodating long, top-heavy hydrometers.
- High Optical Clarity: Flawless glass construction allows for exact meniscus reading without distortion.
- Autoclavable: Can be safely sterilized in an autoclave to prevent cross-contamination between tests.
- Optional Graduation: Select 1000 mL models act as sedimentation cylinders, featuring a permanent volume mark.
