Jianshi Bio TIQB0001 Microfluorescence Quantitative Analyzer (Fluorometer)

Product Overview

The TIQB0001 micro‑fluorometer is a benchtop, high‑precision fluorescence detection instrument specifically designed for the quantitative analysis of trace amounts of nucleic acids, proteins, and fluorescent dyes. It features a stable UV excitation source and a highly sensitive photodetection module, supporting four major assay modes—DNA, RNA, total protein, and fluorescent probes—and can detect samples as low as the pg level without requiring large reaction volumes, enabling accurate quantification with only minute sample quantities. The device is equipped with a high‑resolution color capacitive touchscreen, preloaded with multiple standard calibration curves, and includes one‑click self‑diagnostics that automatically perform blank correction, standard curve fitting, and sample reading. Its fully enclosed, light‑shielded measurement chamber eliminates ambient light interference, ensuring excellent data reproducibility. With a compact, lightweight design that minimizes bench space, it supports USB‑based local data export, storage, and printing, and incorporates a comprehensive quality‑control program that automatically flags outlier values. This instrument is suitable for molecular laboratories, disease control centers, pharmaceutical R&D facilities, and third‑party testing organizations, and is widely used for quality control of nucleic acid extraction, protein concentration determination, and quantitative analysis of fluorescent probes. Operation is straightforward, requiring no complex setup; it can be quickly mastered by a single user and is intended solely for research use (RUO), not for clinical in‑vitro diagnostic applications.

TIQB0001 Fluorescence Detector – High-Frequency FAQ

1: What is the lowest detectable nucleic acid concentration with TIQB0001, and how reproducible is the detection of trace‑low‑abundance samples?

The instrument’s detection limit can reach the pg level, enabling stable detection of extremely low‑abundance nucleic acid samples, with a coefficient of variation (CV) of ≤2.5%.

The instrument features a fully enclosed, light‑shielded detection chamber that completely eliminates external stray light interference. For low‑concentration, precious samples, no gradient dilution is required, and repeated measurements exhibit minimal variability, making it ideal for the precise quantification of trace‑amount extraction products.

2: What types of samples does the instrument support, and do protein samples require special pre‑processing?

It features four independent assay protocols, enabling quantitative analysis of four sample types: double-stranded DNA, single-stranded RNA, total protein, and fluorescent dyes.

For protein samples, simply perform the fluorescence incubation step using the provided kit; no additional lysis or dilution is required. After incubation, the samples can be directly loaded onto the instrument for analysis.

3: Multiple standard curves can be saved. After replacing the assay kit, is recalibration required?

The instrument features built-in local curve storage; factory‑predefined curves are permanently retained, and users can create, name, and retrieve multiple custom standard curves.

Operational Recommendations: When switching between brands or batches of fluorescent quantitative assay kits, it is recommended to re‑configure the standard curve to ensure assay accuracy.

4: How can the completed test data be exported, and can an editable experimental spreadsheet be generated directly?

The device is equipped with a standard USB port; simply plug in a standard USB flash drive to export all test records, which are saved in a universally compatible Excel format.

This device can store more than 1,000 complete sets of test data. For long-term, batch‑type experiments, data can be exported in segments, eliminating the need for manual transcription.

5: How long is the service life of a UV LED light source, and must the entire unit be replaced if the output value drifts?

Equipped with a long-life UV LED excitation source, it boasts a service life of tens of thousands of hours under typical laboratory operating conditions.

Precautions: When continuous drift or linear degradation occurs, only the light source module needs to be replaced, eliminating the need to replace the entire unit and reducing maintenance costs.

6: During the assay, will opening the cuvette cover expose operators to UV radiation?

The equipment is equipped with an automatic safety interlock that cuts off the UV light source when the cover is opened, causing the UV lamp to extinguish simultaneously upon opening.

The entire process emits no direct ultraviolet radiation, preventing eye and skin burns; single-person operation requires no additional protective eyewear.

7: Which tube specifications are compatible with the instrument, and can 1.5 mL centrifuge tubes be placed in the sample holder?

Compatible with 0.2 mL and 0.5 mL micro-volume PCR fluorescence‑specific assay tubes;

Restriction Notice: The cavity slot dimensions are compatible only with microcentrifuge tubes; 1.5 mL and larger centrifuge tubes cannot be accommodated, and forced insertion into the cavity is prohibited.

8: Do high- and low-concentration samples require serial dilutions, and how many orders of magnitude does the instrument’s linear detection range span?

The optical linear range spans five orders of magnitude, allowing most samples across a wide concentration range to be analyzed directly without gradient dilution.

Only when the sample concentration is completely outside the upper limit of the standard curve should it be diluted with the provided buffer and re‑measured.

9: What causes large discrepancies among repeated test results and elevated CV values, and how should this be addressed?

Common causes of failures and corresponding troubleshooting solutions:

1. Fluorescent dye residue adhering to the cavity’s light-transmitting window → Clean by wiping with a soft cloth dampened with purified water;

2. If the outer wall of the test tube is contaminated with liquid or fingerprints, wipe the wall dry before placing it in the slot.

3. Light source aging and degradation → Contact after-sales service to replace the LED light source module.

10: Can the TIQB0001 fluorometer be used for the analysis of clinical in vitro diagnostic samples?

Prohibited for use in the interpretation of clinical in vitro diagnostic tests!

This instrument is designated as a Research Use Only (RUO) device and does not possess medical device registration.
