UNITED

UNITED is a brand of laboratory equipment and consumables, primarily serving the needs of research, clinical, and industrial laboratories. The product line includes bottle top dispensers, transfer pipettes, hot plates, and lab clamps, among other items. UNITED products are designed for routine laboratory tasks requiring precision and reliability. The bottle top dispensers, for example, are available in volume capacities ranging from 2.5 mL to 60 mL, with accuracy specifications such as +0.6/-0.015% for the 2.5 mL model (BTDR-1) and +0.5/-0.300% for the 60 mL model (BTDR-5). These dispensers are intended for use with standard laboratory bottles and are suitable for dispensing reagents, solvents, and other liquids in controlled volumes. The transfer pipettes, such as the sterile 3 mL LDPE model (P31206), are individually wrapped and made from clear low-density polyethylene, offering a disposable solution for liquid handling in sterile environments. UNITED hot plates, like the single-position digital model (HOTPDG), operate at 115V AC with a US standard plug and include a timer, making them suitable for heating samples in various lab applications. Lab clamps, including the aluminum buret clamp (CLBURDD) and die-cast zinc alloy flask clamp (CLPVC2), provide secure holding for glassware during titrations or other procedures. 3G Electric supplies UNITED products globally, supporting procurement specialists and lab managers with a range of items that meet standard laboratory specifications. The brand does not claim specific certifications or industry standards beyond the stated product specifications, and the equipment is generally intended for general-purpose lab use rather than specialized or high-precision applications. Buyers should verify compatibility with their specific protocols, particularly for sterile or volumetric requirements.

Frequently asked questions

Common questions about UNITED from 3G Electric.

What accuracy specifications are available for UNITED bottle top dispensers?

UNITED bottle top dispensers are offered in several volume ranges with specified accuracy. For example, the 2.5 mL model (BTDR-1) has an accuracy of +0.6/-0.015%, the 5 mL model (BTDR-2) has +0.5/-0.025%, the 30 mL model (BTDR-4) has +0.5/-0.150%, and the 60 mL model (BTDR-5) has +0.5/-0.300%. These values indicate the tolerance for volume delivery at the maximum capacity. The accuracy is expressed as a percentage of the set volume, with the positive and negative values reflecting the range of deviation. For precise work, select a dispenser with a capacity close to your required volume to minimize relative error.

Are UNITED transfer pipettes autoclavable?

No, UNITED transfer pipettes, such as the sterile 3 mL LDPE model (P31206), are not autoclavable. They are made from low-density polyethylene (LDPE), which has a melting point around 105-115°C, making them unsuitable for steam sterilization at typical autoclave temperatures (121°C or higher). These pipettes are supplied sterile and individually wrapped, intended for single-use applications. If sterility is required after opening, alternative methods such as chemical disinfection or using a new sterile pipette are recommended.

What is the voltage and plug type for UNITED hot plates?

UNITED hot plates, such as the single-position digital model (HOTPDG), are designed for 115V AC operation and come with a US standard plug type. This voltage is common in North America and some other regions. The unit includes a digital display and a timer for controlled heating. For use in other voltage regions, a step-down transformer or voltage converter may be required. Always verify local electrical standards before installation.

What materials are used in UNITED lab clamps?

UNITED lab clamps are available in different materials depending on the model. The buret clamp (CLBURDD) is made from aluminum, providing a lightweight and corrosion-resistant option. The flask clamp (CLPVC2) is constructed from die-cast zinc alloy, which offers higher strength and durability for heavier glassware. Both clamps feature two prongs for secure gripping. The choice of material affects weight, chemical resistance, and longevity; aluminum is suitable for general use, while zinc alloy is better for demanding applications.

Can UNITED bottle top dispensers be used with corrosive chemicals?

UNITED bottle top dispensers are designed for general laboratory liquids, but their chemical compatibility depends on the materials of construction. The product specifications do not list the wetted materials in detail, so it is essential to consult the manufacturer's documentation or test with small volumes before routine use. For corrosive chemicals such as strong acids or bases, ensure that the dispenser's seals and body are resistant. If in doubt, use a dedicated dispenser rated for the specific chemical.
