Details
Take a closer look at VQ-200.
A compact 96-well real-time fluorescence qPCR system designed for precise thermal control, four-channel detection, and flexible quantification workflows.
Just accurate, open, and affordable qPCR.
VQ-200 is built for 96-well real-time fluorescence qPCR workflows, combining thermal precision, four-channel optical detection, and a wide dynamic range for qualitative, absolute or relative quantification, and melt-curve analysis.
- 96 Well real-time PCR system
- 4 Fluorescence channels
- ±0.1°C Thermal accuracy
- 1-10^10 Copy dynamic range
High-precision Peltier thermal control
The Peltier module supports a 4.0-99.0°C range with max heating of ≥7°C/s and max cooling of ≥5°C/s, giving amplification curves a stable thermal-cycle foundation.
Four-channel fluorescence detection
FAM/SYBR Green, HEX/JOE/VIC/TET, CY5/Texas Red, and ROX channels are captured through a high-power white LED source and CMOS camera.
Reliable quantitative performance
Single-copy sensitivity, ≥0.99 linearity, and ≤1% Ct CV reproducibility support nucleic acid amplification detection and quantitative analysis.
01 Open interfaces, automation-ready
Most qPCR systems lock users into proprietary consumables, bundled computers, and closed analysis algorithms. VQ-200 is designed to keep the workflow open.
Consumable freedom
Compatible with standard 0.1/0.2 mL tubes, 8-strip tubes, and 96-well plates from different manufacturers, without proprietary plastics.
No bundled computer
The built-in 9-inch touch screen and embedded computer let the system run without a separate external PC.
Open analysis algorithm
Acquisition parameters and analysis algorithms can be customized for specific reagent kits, with custom reports and LIMS integration.
Automation ready
Motorized lid, auto-loading chamber, USB/RS485, and dark-lab readiness support robotic integration.
02 On par with leading industry standards
Reference pages 6 and 7 show VQ-200 performance against leading international platforms and imported brands.
Performance validation
SYBR Green CV reaches 0.17%, compared with 0.41% for Brand A and 1.87% for Brand B; amplification efficiency is shown at 100%.
Clinical correlation
HBV testing shows 1.7% error versus reference with R2 = 0.99, and Influenza A testing shows 100% positive agreement.
Resolution and accuracy
High-repeatability, high-resolution, and high-accuracy demonstrations compare VQ-200 curves and Ct consistency with a leading imported brand.
03 Simple 3 steps: prepare, load, run
The workflow is designed for fast setup and one-touch operation.
Step 1: Prepare
Prepare PCR mix and load it into a plate or tubes.
Step 2: Load
Open the chamber, place consumables, and close the auto lid.
Step 3: Run
Select a template, tap Run, and let the system handle the rest.
04 No extra computer, no tied consumables
The VQ-200 cost story is built around performance that competes with leading platforms while keeping ownership flexible.
Use any consumables
Standard tubes, strips, and plates from different brands can be used, so existing lab inventory works and premium proprietary consumables are avoided.
No external PC required
Built-in computer and 9-inch touch screen reduce separate computer purchase and maintenance needs.
Automation without expensive add-ons
Motorized lid, auto chamber, RS485/USB, robotic integration, and dark-lab readiness are part of the system design.
Total cost you control
No mandatory service contracts, no consumables lock-in, and domestically sourced components keep purchase price and operating costs predictable.
