GHM RF-A Drop Stainer and Coverslipper #

🧪 True Drop‑Staining Technology – Zero Cross‑Contamination

Unlike conventional dip‑and‑dunk stainers, the RF‑A uses a dedicated drop‑staining method with ≥18 independent nozzles – no shared pipelines, no reagent carryover. Each slide receives fresh reagent directly, ensuring uniform, reproducible results.

Why it matters: Eliminate the risk of reagent cross‑contamination that can compromise special stains and IHC. Ideal for labs that run a wide menu of stains with high confidence.

---

🚀 40+ Slides per Run – Single‑Layer Turntable Design

The RF‑A holds over 40 slides simultaneously on a single‑layer turntable – no stacking, no complex racks. The drop‑staining workflow is simplified and highly efficient.

Why it matters: Load once and walk away. The simple, open design reduces operator errors and makes loading/unloading fast and intuitive – perfect for busy core labs.

---

⚡ One‑Stop, Fully Integrated Workflow

The RF‑A combines slide baking, deparaffinization, staining, washing, clearing, and coverslipping in one compact instrument. No separate oven, no manual transfer between stations.

Why it matters: Dramatically reduce hands‑on time. From raw slide to finished, coverslipped slide – all in one automated run.

---

🔥 Independent Temperature Control for Baking & Incubation

Each station features independent temperature control:

• Baking temperature: Adjustable from room temperature to 75°C

• Incubation temperature: Adjustable from room temperature to 40°C

Why it matters: Run heat‑sensitive protocols (e.g., enzymatic digestion, antigen retrieval) alongside routine stains with precise, station‑level control.

---

💧 Negative‑Pressure Waste Removal – No Aerosols

The RF‑A uses negative‑pressure suction technology for waste liquid removal – not air blowing. This ensures clean specimen backgrounds and eliminates aerosol contamination that can compromise staff safety and sample integrity.

Why it matters: Safer for your lab personnel. Cleaner slides with less background debris. No risk of cross‑contamination via airborne droplets.

---

🎛️ 20+ Programs, 50+ Steps per Protocol

Store ≥20 programmable protocols with ≥50 steps each. Real‑time progress tracking for every staining station.

Why it matters: Run complex research protocols alongside routine H&E – all on one instrument. Monitor each station’s status at a glance.

---

🧩 Dual Independent Mounting + Dual Drop‑Staining Modules

The RF‑A features two independent mounting modules and two drop‑staining modules. They can operate separately or synchronously with no mechanical linkage – one module can be serviced while the other continues working.

Why it matters: Zero downtime for critical maintenance. Run two different staining protocols simultaneously. True redundancy for high‑uptime laboratories.

---

📥 Continuous Loading – Add Slides Mid‑Run

Need to add an urgent slide? The RF‑A supports mid‑process slide additions without interrupting the ongoing staining. Completed slides can also be retrieved mid‑run without disrupting the rest of the batch.

Why it matters: STAT samples go in immediately – no need to wait for the current cycle to finish. Flexible, responsive workflow for busy pathology labs.

---

🛡️ Smart Coverslipping – Defective Cover Slip Detection

The integrated coverslipper includes intelligent detection for defective or missing cover slips, automatically discarding faulty slips to ensure perfect mounting every time.

Why it matters: No ruined slides from cracked or misaligned coverslips. No manual inspection after mounting.

---

🧪 Large‑Volume Reagent Tanks – Up to 3,000ml

Each reagent tank holds 3,000ml – among the largest in its class. Tanks feature push‑pull access and built‑in liquid level detection.

Why it matters: Run for days or weeks without refilling. Push‑pull design makes tank replacement quick and spill‑free. Level detection alerts you before running dry.

---

📦 Compact, Fume‑Hood Compatible Design

Overall dimensions designed to fit inside a standard fume hood: ≤1.5m (L) × 1m (W) × 0.8m (H). The integrated staining and coverslipping in one device saves valuable bench space.

Why it matters: No need for custom ventilation. Fits where your lab already works. Smaller footprint than separate stainer + coverslipper systems.

---

🖥️ 12.3‑Inch Touchscreen with Voice Reminders

The RF‑A features a large 12.3‑inch touchscreen – the largest in KFBIO’s stainer series – plus voice reminders to alert technicians when cycles complete, reagents are low, or attention is needed.

Why it matters: Big, clear interface reduces operator strain. Voice alerts let you multitask without watching the screen.

---

🧠 Stationary Slide Processing – No Tray Movement

During drop‑staining and baking, slides remain stationary – the reagent nozzles move, not the slide tray. This eliminates vibration and ensures consistent reagent coverage.

Why it matters: Fragile or loose sections stay in place. No wash‑off artifacts. Ideal for cytology and delicate tissue specimens.

---

🔬 Built‑in Automatic Slide Drying

The system includes built‑in automatic slide drying that reduces cooling time between steps, speeding up the overall staining cycle.

Why it matters: Shorter total run times. Slides are ready for coverslipping faster without manual drying.

---

✅ CE‑IVDR Certified – Diagnostic Ready

The RF‑A is CE‑IVDR certified, meeting the latest European regulatory standards for in vitro diagnostic medical devices.

Why it matters: Deploy with confidence in regulated diagnostic labs worldwide.

---

🌍 Global Power Ready – 100–240V, 50/60Hz

Operates on 100–240V AC, 50/60Hz with interchangeable power sockets (Types A, C, D, E/F, G, I, J, L, M).

Why it matters: Same instrument works anywhere. No transformer needed.
