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…

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…

Three styles available for our NMR and EPR Tubes 1187C59 (820-A): Lightweight polypropylene rack maximizes your benchtop storage capacity and is virtually inert 1187C64 (WG-2442): Simple but useful this stainless steel NMR tube rack accommodates 12 tubes with a maximum OD of 5mm.…

Getting a tiny powder sample into any tube larger than 4mm OD should never be a struggle again. Unlike ordinary spatulas, WILMAD's Stainless Steel NMR Spatula fits into the most common NMR tubes. Add or remove samples easily (including freeze-dried); scoop samples with the round end or pry…

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…

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.

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 Light weight for simple tare settings Manufactured from ASTM Type I, Class A borosilicate

Wilmad Long-Tip Sample Transfer NMR Pipettes are designed for easy transfer of liquid samples contained in 5mm OD NMR tubes, long neck volumetric flasks or chromatography columns. Manufactured from high quality ASTM Type 1 Class A glass Resistant to most organic solvents Transparency…

Calibrated "to deliver" at 20°C, these borosilicate glass pipettes have a permanently colored amber scale with the zero line at the top. The small amount remaining in the tip, after completion of free delivery, is blown out and added to the main delivery volume (ground band indicator…

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.

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

This borosilicate glass Air-Tite vacuum gas manifold (Schlenk line) is designed with double oblique pressure/vacuum stopcocks with 4mm bores and a 16.2/56 plug size. The stopcocks simplify evacuation or pressurization with an inert atmosphere. Manifold is 1" O.D.

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…

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…

Product is used extensively with volumetric flasks and separatory funnels.

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…

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.
