BR‑003T Automatic Gram Slide Stainer

Drip & Spray Dual‑Mode Automated Gram Staining System

Product Overview：

The BR‑003T automatic gram slide stainer is designed for bacterial and fungal smear staining in clinical hospitals,

CDC and microbiology laboratories. It integrates drip‑type (injection) and high‑pressure spray staining in one

unit with one‑click switching. Independent fluid channels eliminate cross‑contamination. After staining, slides

are centrifugally dried and ready for direct microscopic examination. It supports both 3‑step and 4‑step

standardized Gram staining protocols to deliver stable, repeatable staining results, reducing manual errors.

drip & spray one‑click switch control, independent reagent fluid paths, and side view of the staining machine.

The BR‑003T integrates several user‑centric design details, from batch slide loading and dual‑mode staining to

independent reagent pipelines, helping laboratories achieve standardized, safe and efficient gram staining.

Key Advantages：

✅1.Drip & Spray Dual‑Mode One‑click Switch.

Spray mode saves reagent consumption; drip‑type features large‑aperture design to avoid nozzle clogging.

✅2.Fully‑Independent Fluid Path for Each Reagent.

Separate pumps, tubes and nozzles for every staining reagent. No cross‑contamination or residual reagent

interference.

✅3.Fine‑tuned Staining for Different Sample Types.

Optimized preset settings for sputum/vaginal secretions, urine/body fluid, blood culture samples. Users can freely

adjust staining duration and reagent dosage according to smear thickness.

✅4.Brushless DC Motor System.

No spark risk, low noise, low power consumption and long service life. Fully‑closed structure keeps lab

environment clean,no water sink required.

✅5.Automatic Centrifugal Drying After Staining.

Slides are dried inside the instrument. Finished slides can go directly to microscopy without extra manual

handling.Optional cytocentrifuge rotor for body fluid sample enrichment.

✅6.Convenient Maintenance & Safety Lock Design.

One‑touch alcohol cleaning for fluid path, special pipeline rinse and spray volume detection. Electromagnetic

safety lock:machine only runs when cover is closed. Alarm for low reagent and equipment faults.

BR‑003T Stainer Rear‑Panel Details：

The rear panel integrates ventilation holes, power supply, data communication, waste discharge and reagent tray. 

Reasonable layout ensures heat dissipation, convenient connection, smooth waste liquid discharge and easy

reagent handling.

Main Performance & Working Features：

✅1.Fully‑automatic staining workflow: load slides only, no manual intervention during operation.

✅2.Support both standard 3‑step and 4‑step Gram staining protocols, switch freely.

✅3.Adjustable staining grade: Spray mode grade 1‑9; Drip mode grade 1‑5. Reagent spray volume

      customizable.

✅4.Batch capacity: 1‑16 slides configurable.

✅5.Staining speed:

      -Spray staining: 4‑5.25 min per run, max 180 slides/hour

      -Drip staining: about 7 min per run, max 137 slides/hour

✅6.Slide flat‑placement design, separate position for each slide to avoid cross‑contamination between

      specimens.

✅7.Support centrifugal drying for external pre‑stained slides.
