  • Used to determine the specific gravity/density of sand, cement and other fine materials, this borosilicate glass specific gravity bottle is developed from ASTM C 188 and ASTM E 694. The body holds approximately 250mL and the capacity of the oval bulb in the neck is 17mL. Volume below the bulb is…

  • NMR/EPR Tube Caps

    SP Wilmad-LabGlass

    Our PTFE NMR/EPR Tube Caps are machined to exact specifications with smaller gyroradius and more homogeneous mass distribution than disposable caps providing better spinning stability. They are recommended for experiments at high - ultra high field and those using Chloroform as the reference…

  • These borosilicate glass specific gravity bottles are accurately adjusted at 20°C to determine the density of liquid samples. While the joints have Standard Taper dimensions, the capillary stoppers are not interchangeable since the final adjustment for volume is made on the stopper. Each bottle…

  • Hubbard Specific Gravity Bottle

    SP Wilmad-LabGlass

    This borosilicate glass specific gravity bottle is used in standard test methods for specific gravity of a variety of semi solid materials and emulsions, such as asphalt cements, road tars, road oils, and soft tar pitches. The solid Standard Taper stopper has a hole approximately 1.6mm in diameter…

  • Precision Rubber Septa Caps

    SP Wilmad-LabGlass

    Engineered for a "push on" fit in NMR tubes and ampules. The unique design provides a penetration point for cannulation and a dual seal inside the tube and on the outer sleeve. Will not break delicate, thin-wall tubing. Manufactured from one certified raw material formulation for absolute…

  • With closed bottom standard taper pennyhead style stopper Pennyhead stopper forms a secure seal Wide opening for easy addition and removal of samples Light weight for simple tare settings Manufactured from ASTM Type I, Class A borosilicate

  • With closed bottom standard taper pennyhead style stopper Pennyhead stopper forms a secure seal High form shape decreases bottle footprint Light weight for simple tare settings Manufactured from ASTM Type I, Class A borosilicate

  • Carboy with Hose Connection

    SP Wilmad-LabGlass

    Large capacity borosilicate glass bottles, offered in four different sizes, feature a hose connector sealed at neck (1/2 or 3/8" connection). All bottle necks are compatible with a #12 stopper.

  • Gas Collecting Tubes

    SP Wilmad-LabGlass

    Featuring a side outlet in the body for a self sealing syringe stopper, these borosilicate glass Gas Collecting Tubes are useful in gas chromatography or mass spectroscopy. Stopcocks have PTFE plugs. For additional rubber stoppers, see ML-1940.

  • Caps can be used as weighing dishes External standard taper joint allows for sample transfer without seal interference Flat top permits stacking for increased desiccator capacity High form shape decreases bottle footprint Light weight for simple tare settings Manufactured from ASTM…

  • Solid State NMR Cap Remover

    SP Wilmad-LabGlass

    One of the most challenging parts of a solid state NMR experiment is to remove the end cap or base plug. This Zero turn cap remover eliminates possible damage of the cap and rotor.

  • These unadjusted borosilicate glass specific gravity bottles determine the density of liquid samples. They have capillary stoppers, and ground Standard Taper joints to reduce evaporation.
