Acid work is where a sample-prep lab loses time and takes risks. LabTech moves the operator away from the fume hood instead: an automated dispenser that adds corrosive reagents through PFA tubing, a digestion system built on a 360° rotating robotic arm, and a shaking water bath whose wetted parts are plastic or coated steel. Each unit is designed around the same constraint, that acid vapor destroys anything it can reach.

Operator away from acid

PAD control and wireless links keep staff out of the fume hood during corrosive reagent handling.

Six channels, auto-clean

Acid6 switches between corrosive reagents across six PFA-lined channels and rinses itself afterward.

Dual-module throughput

The automated digestion system runs two independent modules, so two sample types progress at once.

Exhaust built in

An integrated acid fume exhaust and HEPA-grade filtered intake protect samples and bench space.

Models

Choose the configuration.

Automation here is procedural rather than decorative. Acid6 holds six reagent channels with automatic cleaning, so a batch can take different acids at different positions. The automated digestion system runs two independent modules at once and reports status over a wireless link. The VB77 and the shaking bath cover the narrower jobs: urine iodine and 16 mm tube digestions, and extractions that need constant agitation at a controlled bath temperature.

Acid6

Automated acid dispensing instrument with six reagent channels

A benchtop dispenser that adds corrosive reagents without an operator at the hood. A high-precision peristaltic pump feeds six channels through PFA tubing, and an XYZ three-axis arm positions the probe over different vessel types. The integrated exhaust, HEPA-grade filtered intake, hood lighting and delayed fan shutdown keep the working area clean, visible and free of acid vapor.

Automated digestion system

Automated digestion system with dual independent modules

A walk-away digestion platform for environmental, food and cosmetic samples. A 360° rotating robotic arm handles positioning, and two independent modules let two different sample types run in the same session. Built-in standard digestion methods keep runs reproducible, and wireless remote monitoring reports status while the analyst is elsewhere in the building.

Anti-corrosion shaking water bath

Shaking water bath with corrosion-resistant wetted parts

A water bath for extraction and digestion steps that need continuous agitation. The bath is stainless steel with an anti-corrosion coating, and the operating platform and racks are all plastic, so acid drips do not start rust. A transparent reflux cover holds heat and cuts water loss, while refill is automatic with an adjustable flow to prevent temperature overshoot.

VB77 urine iodine digester

Urine iodine digester for 16 mm tubes

A dedicated digester for urine iodine testing, and for any method that runs in 16 mm tubes. Wrap-around heating keeps all 77 positions at the same temperature, within ±1 °C at 100 °C, and an intelligent PID system holds the set point. A timed heating mode lets the batch finish without an operator standing over it.

Questions

Before you buy.

How does Acid6 keep the operator away from corrosive reagents?

Acid6 connects over a wireless link to a PAD touchscreen, so the analyst sets up and monitors dispensing without standing at the hood. On the instrument side, an integrated acid fume exhaust removes vapor without consuming fume hood space, a HEPA-grade push-filtered intake keeps samples clean, and multiple warning functions guard the run. Reagents travel through PFA tubing in six switchable channels.

Can the automated digestion system run two different sample types at once?

Yes. The system has two independent digestion modules, so a batch of environmental samples and a batch of food or cosmetic samples can progress in the same session. A 360° rotating robotic arm provides the positioning, built-in standardized methods keep the program repeatable, and wireless remote monitoring lets the run continue without an operator in the room.

What tube size does the VB77 take?

The VB77 is built around 16 mm tubes, the format used for urine iodine digestion and for COD digestions. It holds 77 samples at once with wrap-around heating and ≤±1 °C well-to-well variation at 100 °C, and its timed heating mode means a batch can finish without supervision.
