In scientific and diagnostic laboratories, the reliability of experimental data depends not only on the quality of reagents or assay kits but also on the performance of analytical instruments. For assays built on colorimetric reactions—such as ELISA tests, enzyme activity monitoring, and cellular viability measurements—the microplate reader occupies a central position in the workflow. Its ability to convert biological reactions into optical signals helps laboratories produce quantitative results that support research conclusions, clinical decisions, and quality control processes.
The Microplate Reader DR-200Bc (LED Light), developed by Diatek, is widely used in hospital laboratories, disease control centers, research institutions, veterinary clinics, and food testing facilities. Beyond its measurement principles, the real impact of the DR-200Bc is best understood by examining how it fits into day-to-day laboratory routines.
This article approaches the instrument from a workflow perspective, showing how it supports efficiency, consistency, and operational reliability in environments where accuracy and repeatability are essential.

A Reader Designed for the Realities of Daily Lab Work
Modern laboratories operate under intense pressure: increasing sample volumes, tight reporting deadlines, and the need for reproducible data across different operators and shifts. A microplate reader must therefore do more than provide correct measurements—it must integrate seamlessly into a structured workflow.
The DR-200Bc LED microplate reader supports this by offering fast, stable optical density (OD) readings across standard 96-well plates. From sample preparation to data export, the workflow becomes more predictable, helping teams reduce bottlenecks.
Consistent Optical Output for Reliable Runs
LED illumination produces stable light intensity, which helps minimize one of the most common sources of assay variability: changing light conditions. Since the light source does not drift during use, laboratories can perform multiple plate readings in a single session without recalibration. This matters for:
-
ELISA batches
-
enzyme kinetic assays
-
serial dilution experiments
-
multi-step biochemical tests
Consistency ensures that results from the first sample batch remain comparable with those measured later in the day.
High-Throughput Capability and Time-Saving Benefits
In many laboratories, time efficiency directly affects the quality of work. For example, clinical diagnostic labs must deliver timely results for patient management, while research groups often run multiple assays to compare experimental conditions.
Parallel Processing in a 96-Well Format
Using a 96-well microplate allows scientists to evaluate many samples under identical conditions. This reduces human error and lowers the amount of reagent required per test.
With the DR-200Bc, technicians can:
-
load a full plate
-
perform automated OD measurement
-
repeat for multiple plates in sequence
This is faster and more reliable than single-sample optical devices and supports laboratories that process high sample numbers daily.
Supporting Assays Across Multiple Disciplines
The DR-200Bc is used not because of a single specialty but because it works across diverse testing environments. Each sector benefits from the instrument’s ability to measure absorption accurately and reproducibly.
1. Clinical and Medical Laboratory Workflows
Hospitals and clinics routinely use colorimetric tests to detect and quantify biomarkers in patient samples. When the results influence diagnosis or treatment planning, accuracy becomes non-negotiable.
The DR-200Bc supports:
-
routine ELISA panels
-
immune response monitoring
-
infectious disease screening
The reader’s stable LED-based measurements contribute to consistent clinical interpretation.
2. Scientific Research and Experimental Optimization
Research laboratories require tools that help them test hypotheses, validate findings, and troubleshoot experiments. For researchers conducting biochemical or cell-based assays, OD readings provide crucial quantitative insight.
Typical applications include:
-
enzyme reaction monitoring
-
protein concentration measurement
-
cell viability testing in 96-well plates
The DR-200Bc fits into these workflows by providing reproducible readouts that allow scientists to compare experiments over days or weeks.
3. Veterinary Diagnostics
In veterinary disease detection, microplate assays offer fast and accessible methods for identifying pathogens or monitoring antibody levels in animals.
The DR-200Bc supports veterinary clinics and animal health laboratories by enabling:
-
pathogen screening
-
herd monitoring programs
-
post-treatment evaluations
Because LED-based readings remain stable across repeated assays, veterinary professionals can rely on consistent test results for herd-level decisions.
4. Food Safety and Quality Monitoring
Food testing laboratories frequently use colorimetric assays to check for contaminants such as mycotoxins, allergens, and microbial byproducts.
The DR-200Bc supports these workflows by delivering consistent OD readings used in:
-
toxin quantification
-
pathogen detection
-
quality assurance tests
Fast plate processing helps reduce turnaround time for food safety reports.
Reducing Operational Challenges in Lab Testing
Many of the difficulties in laboratory testing do not come from the biological materials but from unexpected instrument behavior. Variation from light source degradation, temperature drift, or inconsistent calibration can cause results to deviate from expected values.
The DR-200Bc minimizes these issues in several ways:
Stable LED Illumination
LEDs provide long-term light consistency without requiring frequent replacement. This is particularly helpful for labs that run daily or weekly testing schedules.
Low Thermal Output
Minimal heat generation reduces the risk of sample temperature changes during measurement—an important factor in enzyme and kinetic assays.
Predictable Measurement Performance
Because optical drift is low, laboratories can compare historical data with new results more confidently, improving the reliability of long-term studies.
