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…

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…

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…

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.

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.

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.

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…

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…

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

Traditionally, sample sizes are 3-5 times the height of the probe R f coil. All magnetic field distortions caused by susceptibility discontinuities at the upper air-sample and lower glass-sample interfaces were far from the sensitive probe R f coil region. Small samples diluted to larger…

The superior pressure cap is ideal for experiments that requires a simple gas tight seal under 1.5 bar. Recommended to use with Wilmad medium wall or heavy wall tube. This cap would not allow syringe puncture. Use heat gun to soften the cap and apply on the tube. Once the cap is cooled down, a gas…

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

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.

Wilmad 4 inch (-102 mm) long Agilent Precision Automatic Sample Changer Tubes have the tightest outer diameter tolerance (0.0065 mm) to prevent jamming. Cap for Automatic Sampler Only.

Traditionally, sample sizes are 3-5 times the height of the probe R f coil. All magnetic field distortions caused by susceptibility discontinuities at the upper air-sample and lower glass-sample interfaces were far from the sensitive probe R f coil region. Small samples diluted to larger…

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…
