In research settings, small errors can lead to big problems. Whether you’re measuring out reagents, preparing biological samples, or calibrating instruments, accuracy matters. That’s why Arlyn Scales builds weighing systems designed specifically for labs that can’t afford to guess.
Our ultra-precision scales use a patented technology called SAW (Surface Acoustic Wave) — which provides around 10x better accuracy than standard strain gauge systems, while staying in the same price range.
Why Labs Need Better Scales
Fields like pharmaceuticals, chemistry, and biotech often deal with tiny quantities of materials. If your readings are off, your results are at risk. You might have to repeat the work, or worse, publish data that isn’t reproducible.
Scales with true ultra-precision help avoid that. They don’t just meet tolerances — they give you a level of confidence that’s hard to get from older systems.
What SAW Technology Does Differently
Most industrial scales use strain gauges that measure force and rely on analog signals. SAW scales work differently. They use surface acoustic waves to detect very small changes in distance, without stressing the sensor.
Here’s what that means in practice:
- Digital readings with no lag
- More stable results, even in changing lab environments
- Quick response to weight changes — usually within half a second
Designed for the Lab, and also the Factory
These scales are built at our New York facility, not mass-produced overseas. They have:
- A die-cast aluminum frame and stainless-steel pan
- Built-in factory calibration
- Shock protection that handles up to 5x the rated capacity
You can expect the same build quality as a top-tier laboratory use, but rugged enough for factory use.
Scale Responsiveness That Keeps Up
Some materials don’t sit still — they react to air, heat, or light. If you’re working with substances that need to be weighed and moved quickly, slow updates or drifting readings can be a problem. SAW scales avoid that with real-time digital feedback, updated every 0.4 seconds.
Choose the Right Capacity
SAW scales are available from 10 lbs up to 1000 lbs. The resolution stays high, even at higher capacities, but for lab use, you’ll usually get better results sticking with the smallest capacity that covers your typical sample range.
Better Creep Resistance
“Creep” is what happens when a scale’s reading drifts after something sits on it too long. Our SAW sensors have an industry-best 1:40,000 creep rating — much better than the 1:5,000 you’ll see on high-end strain gauge models.
That matters if you’re running long tests, drying samples, or monitoring weight over time.
Easy Data Integration
All models come with:
- An LCD digital display
- Multiple weight units
- Stability monitoring, check weighing, and parts counting
- Optional RS-232 connectivity
You can also upgrade with:
- USB or Ethernet connections
- Software for logging into Excel or Access
- Full support for LIMS or other lab systems
Made for Real Research Work, or Heavy Factory Work
You can use these for everything from 0.05g samples to 500 lb drums. No matter what you’re weighing, you’ll get quick, reliable results without the usual drift or delay.
- Fully digital output
- Lab-ready construction
- Built in the U.S., backed by a 1-year warranty
