Specifications

The Mettler Toledo Piston F/DV1020/DV920 Burette 51107117 is a specialized component designed for precise volumetric measurements. Its primary function is to perform duties ranging from simple drop counting to complex volumetric calculations. The integrated spirit burner is a unique feature, designed to provide hot gas to the piston, thereby maintaining a constant volume and preventing sample degradation from acids or alkalis.

This consistent temperature control is crucial for highly accurate titrations, especially when working with thermally sensitive solutions. The sealing mechanism is engineered for a tight and leakproof fit, a non-negotiable requirement for preventing reagent loss and ensuring accuracy. Furthermore, the construction is robust enough to withstand a good deal of weight, indicating durability and a solid build.

The burette’s surface is air-tight and chemical-resistant, a critical factor in preventing sample contamination. This ensures the purity of the dispensed liquid remains uncompromised. At the mouth of the burette, a sealing ring is present, contributing to the overall leakproof design.

A notable internal mechanism is the worm gear mechanism, which likely aids in the fine adjustment and smooth operation of the piston. Filling the burette involves a specific procedure: first, compressing the bulb and a safety clip, then inserting the tip into the burette, replacing the bulb, and finally tightening a set screw. This method is designed to ensure an air-free fill.

Performance & Functionality

In terms of performance, the Mettler Toledo Piston F/DV1020/DV920 Burette 51107117 excels. Its core function of dispensing precise volumes is executed with exceptional accuracy.

The spirit burner technology is a standout feature that directly impacts performance, particularly when dealing with challenging sample types. It effectively minimizes errors that could arise from thermal expansion or contraction of the dispensed liquid, ensuring consistent volume delivery. The leakproof sealing is another critical functional aspect, guaranteeing that every micro-liter dispensed is intended.

Strengths lie in its unwavering precision, durability, and the innovative spirit burner feature. The air-tight and chemical-resistant surface also contributes significantly to its functional superiority, safeguarding sample integrity. A potential area for minor improvement, if one were to nitpick, might be the learning curve associated with the specific filling procedure for absolute beginners, though this is standard for precision volumetric glassware.
