CHEMGLASS

CHEMGLASS is a manufacturer of laboratory glassware and related equipment, serving research, analytical, and industrial laboratories. The brand is recognized for producing borosilicate glass items that meet Type I, Class A volumetric standards where applicable, ensuring dimensional accuracy and chemical durability. 3G Electric supplies a range of CHEMGLASS products, including NMR tubes, sample vials, distilling flasks, clamps, and stirring bars, supporting laboratory workflows from sample preparation to analysis. The product line covers common labware such as boiling flasks, graduated cylinders, and condensers, as well as specialized items like egg-shaped PTFE stir bars and amber vials for light-sensitive compounds. CHEMGLASS items are typically constructed from borosilicate glass (e.g., 33 expansion, low alkali) or PTFE for chemical resistance, with closures available in PTFE or polypropylene. Specifications include body diameters from 5 mm (NMR tubes) to 28 mm (vials), volumes from 0.3 mL to 200 mL, and compatibility with standard joint sizes (e.g., 14/20, 24/40). Clamps are offered in zinc alloy with nickel plating or stainless steel, with jaw openings and prong configurations for secure apparatus mounting. 3G Electric stocks these items in various configurations—graduated or plain, with or without closures, and in colorless or amber glass—to match application requirements. Logistics support includes global shipping and inventory management, enabling procurement specialists to source individual components or bulk quantities for laboratory setups. The brand’s focus on reproducible quality makes it suitable for pharmaceutical quality control, environmental testing, and academic research where glassware integrity is critical.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang CHEMGLASS dari 3G Electric.

What glass types are used in CHEMGLASS NMR tubes and vials?

CHEMGLASS NMR tubes and sample vials are typically made from borosilicate glass, which offers low thermal expansion and resistance to chemical attack. The amber-colored tubes and vials contain additives to block UV/visible light, protecting light-sensitive samples. These items are not graduated unless specified, and closures (when included) are often PTFE-lined for inertness. The glass meets Type I, Class A standards for volumetric accuracy where applicable.

Are CHEMGLASS clamps compatible with standard lab frames?

Yes, CHEMGLASS clamps such as the CG-145-04 and CG-9205-04 are designed to fit standard laboratory support rods and frames. The CG-145-04 has a 1/2-inch overall height and a base that accommodates rods up to 1/2-inch diameter. The CG-9205-04 is a 3-prong clamp with a 6.5-inch overall length, made of zinc alloy with nickel plating for corrosion resistance. Both are suitable for securing glassware in typical benchtop setups.

What closure options are available for CHEMGLASS sample vials?

CHEMGLASS sample vials are offered with or without closures. When included, closures are typically PTFE (polytetrafluoroethylene) for chemical inertness and high-temperature resistance. Screw closure sizes vary by vial, such as 24-400 mm for 40 mL vials or 12 x 32 mm for 0.3 mL vials. Some vials are self-standing with a round bottom, and closures are not included on all models—check the product specifications for each SKU.

Can CHEMGLASS distilling flasks be used with standard stoppers?

Yes, CHEMGLASS distilling flasks like the CG-1512-59 are designed with a 14/20 compatible stopper size, meaning they accept standard 14/20 ground-glass stoppers or adapters. The flask has a 200 mL capacity, a round bottom, and is made from colorless borosilicate glass (Type I). This compatibility allows integration with common distillation apparatus without custom fittings.

What is the material and autoclavability of CHEMGLASS stirring bars?

CHEMGLASS stirring bars, such as the egg-shaped CG-2005-30, are made from PTFE (polytetrafluoroethylene), which is chemically resistant and non-stick. They are autoclavable, allowing sterilization at standard temperatures (typically 121°C). The bar measures 9.53 mm in length and 4.76 mm in diameter, with a white color. PTFE construction ensures compatibility with aggressive solvents and acids.
