BK-FP Series Flame Photometer / Spectrophotometer
SKU BIO-0396-BK-FP6450
$4,790.00 - $6,490.00
IncludesStandard care · Standard delivery
The BK-FP series offers flame-based elemental analysis in two precision tiers.
The Flame Photometer (B-suffix models) measures K, Na, Li, Ca, or Ba in 2–4 channel configurations from $4,790. The Flame Spectrophotometer provides tighter reproducibility (≤2%) and lower sample uptake (<3 mL/min) across 1–5 channel models from $5,390. Both share LPG fuel, 7-inch touchscreen, one-touch ignition, and gas-leak safety shutoff.

Overview
The BK-FP series uses flame emission spectroscopy — thermal energy from an LPG flame excites alkali and alkaline-earth elements to emit characteristic wavelengths, which are detected by dedicated optical filters and photodetectors. Two instrument tiers share the same platform and safety architecture: the Flame Photometer (B-suffix models) for cost-effective multi-element screening, and the Flame Spectrophotometer for higher-precision analytical work. Both feature a 7-inch colour touchscreen, one-touch ignition, gas-leakage alarm with automatic gas cutoff, flame-out detection, and storage for up to 20 calibration curves.
Scientific use
Routine sodium, potassium, lithium, calcium, and barium measurement in prepared liquid samples.
Quantifying alkali and alkaline earth metals in prepared water, soil extract, and wastewater samples.
Buying fit
Use this product when the model fit, setup requirements, accessories, and support needs should be confirmed before purchase.
Features & benefits
K/Na detection with ≤0.156 ppm LOD for K and ≤0.184 ppm LOD for Na
Sensitive detection limits enable accurate quantification of trace metal concentrations in dilute biological and environmental samples.
Configurable element combinations (K/Na, K/Na/Li, K/Na/Ca, K/Na/Ba)
Application-specific configurations optimize analytical coverage for different sample types and research requirements.
Flame emission spectroscopy measurement principle
Well-established analytical technique provides reliable, interference-resistant measurements with straightforward sample preparation protocols.
How it works
Flame photometry operates on the principle of flame emission spectroscopy, where sample solutions are atomized in a controlled flame environment. The thermal energy of the flame excites metal electrons to higher energy states, and as these electrons return to ground state, they emit characteristic wavelengths of light specific to each element.
The instrument aspirates liquid samples into an air-fuel flame where atomization and excitation occur simultaneously. Emitted light passes through optical filters or monochromators that isolate specific wavelengths corresponding to target elements. Photodetectors measure emission intensity, which correlates directly with elemental concentration following Beer-Lambert principles.
Multi-channel configurations enable simultaneous detection of multiple elements by employing separate optical pathways and detectors for each target wavelength. This parallel analysis approach increases throughput while maintaining measurement precision across the analytical range.

Unpack and Inspect
Remove instrument from packaging and verify all components are present and undamaged. Check flame photometer housing, gas connections, and optical components for shipping damage.
Gas Supply Connection
Connect appropriate fuel gas (typically propane or natural gas) and compressed air lines to designated inlet ports. Verify all connections are secure and leak-free using appropriate detection methods.
Sample Introduction Setup
Install sample aspiration tubing and nebulizer assembly according to manufacturer specifications. Ensure proper alignment and secure connections for consistent sample uptake.
Optical Alignment Verification
Power on instrument and verify optical system alignment using built-in diagnostic functions. Confirm detector response and wavelength calibration for all active channels.
