Nüve NT 715 Hematocrit Centrifuge Device Analysis Report

Device Identification and Description

The device shown in the visuals is a desktop-type centrifuge used in medical laboratory environments. Upon examining its internal structure, rotor design, and dimensions, it is understood that this device is a hematocrit centrifuge specifically designed for blood counting and separation processes using capillary tubes. The device consists of an outer casing, a control panel, and a rotor chamber.

Brand and Model

As a result of the logos and typographic prints on the product’s front control panel, the brand and model information has been identified with 100% certainty.

• Brand: Nüve
• Model: NT 715

On the black panel on the front face of the device, the “nüve” logo is clearly visible in the upper right corner, and the “NT 715” model designation is clearly readable in large, yellow lettering in the lower right corner.

Areas of Use

This device is used in laboratories for the purpose of separating liquid samples, especially blood, into their components. The NT 715 model is designed for hematocrit tests (separation of the cellular part of blood from plasma) thanks to its special disk (rotor) structure. It rotates tubes at high speed using centrifugal force.

Originality and Origin

The overall production quality of the device, the design language specific to the “nüve” brand (yellow-black panel, gray body), the fonts used, and the neatness of the labels indicate that the product is original. No findings suggest that it is a third-party or copy production.

General Condition and Physical State

The device is in “used” condition, but its integrity has been preserved.

• Outer Casing: There are wear and tear marks on the gray metal body due to use. Paint chips (small black spots that could be the start of corrosion) are particularly visible on the lid edges and corners. However, no major dent or crack has been detected on the body.
• Lid Mechanism: The upper lid hinges appear solid, and the lid can stand upright. The latch tongue that secures the lid when closed is intact.
• Cleanliness: General dust and light dirt accumulation are present throughout the device and in the corners. The device requires professional cleaning and maintenance.

Mechanical and Electronic Component Analysis

The mechanical and electronic controls of the device are provided via the front panel:

• Timer: A mechanical/analog time adjustment knob, labeled “min.” (minute) and scaled from 0 to 15, is present on the panel. The knob cap is black and appears robust.
• Power Switch: A green, presumably illuminated “I/0” (On/Off) switch is located on the panel. The switch is physically intact.
• Rotor (Rotating Head): Inside the chamber, there is a numbered metal disc rotor for placing capillary tubes. In visual 3, it is clearly seen that the rotor is metal and has numbered slots. The central fixing nut is in place.

Accessories and Part Condition

The following parts accompanying the device have been identified in the visuals:

• Inner Protective Lid: In visual 2, a dark gray, centrally screwed protective lid, which covers the rotor, is present. This part is used to ensure safety and reduce air resistance during operation.
• Power Cable: The device’s power cable and plug are not fully visible in the visuals, therefore no comment can be made regarding the cable’s condition.

Label and Warning Analysis

Original labels informing the user and ensuring safety are present on the device:

• Top Lid Warning: On the outer part of the lid, a label with a red exclamation mark states “DO NOT OPERATE WITHOUT READING THE USER MANUAL!..” The label is slightly worn but readable.
• Inner Lid Warning: On the inner part of the lid, a green-framed label states “PLEASE use glass tubes opposite each other and ensure they are well placed.” This warning is critical for ensuring rotor balance.
• Technical Information Label: A label containing technical specifications is visible on the left side surface of the device, but due to the camera angle and resolution, specific data such as serial number, voltage value, or year of manufacture on this label cannot be read.

Assessment and Potential Risks

Based on the visual analysis of the device, the following conclusions can be drawn:

• Potential Risks: Paint chips on the outer casing may increase the risk of rust in humid environments. Additionally, since the timer is a mechanical part, the sensitivity of the knob should be tested. As the power cable is not visible, the electrical connection point should be checked.
• Fault Status: Visually, there is no concrete evidence (such as broken hinges, missing knobs, burn marks, etc.) to indicate that the device is “faulty.” However, the device’s plugged-in and operational status is not seen.
• Missing Items: Sample tubes (capillary tubes) are not present in the visuals; the user must procure these consumables separately.

Summary

The Nüve NT 715 examined is a laboratory device that physically exhibits cosmetic wear (paint chips, dirt) commensurate with its age, but structurally maintains its integrity. Its rotor, inner lid, and control knobs appear complete. Original warning labels are intact. The device has the potential to perform its function with appropriate maintenance and cleaning.
