The H3770-CSTF is the clamp assembly with inert Teflon probe for the H3770 hotplate / stirrer family, sold at $268. $160 step-up over the rod-only H3770-CS ($108). It adds a chemically-resistant Teflon-coated temperature probe for caustic / corrosive sample workflows where standard probes would degrade.

List price$268

When to Pick the Teflon-Probe Variant

Pick the H3770-CSTF when:

  • Workflow involves caustic / corrosive samples (strong acids, strong bases, organic solvents)
  • Direct-contact temperature measurement in chemically reactive media
  • Bundled procurement. Single SKU includes everything (vs sourcing rod + clamps + probe separately)
  • Replacement / spare for damaged Teflon probe

Stay with H3770-CS ($108) when standard thermometer / probe is already in inventory or the workflow doesn't require chemical-resistance.

Ordering & Configuration

Pair with H3770 hotplate / stirrer chassis.

Confirm probe-temperature-range with Benchmark Scientific tech support, Teflon-coated probes typically rate to ~250 °C; verify match to workflow temperatures.

Confirm at quote: chassis pairing, intended caustic-sample workflow, probe temperature range, and lead time.

Warranty: Per Benchmark Scientific standard accessory terms.
