The IPS2050-P-T2 is the centrifugal PTFE (Teflon) impeller in the IPS2050 overhead stirrer accessory line, the chemical-resistant equivalent of the stainless IPS2050-P-S2 sister, sold at $172 ($62 premium over the $172.00 stainless version). Same radial flow pattern, different material: PTFE construction extends the centrifugal-dissolution workflow to aggressive solvents, strong acids, strong bases, and oxidizing chemistries.

Why a PTFE Centrifugal Impeller: Aggressive-Chemistry Dissolution
The centrifugal geometry produces strong shear at the impeller tip for fast dissolution of solids and fast emulsion homogenization, the same flow pattern as the stainless -S2 sister, but in a material inert to aggressive chemistries. The PTFE centrifugal impeller is the right pick for dissolving solids into aggressive-solvent or strong-acid / strong-base liquid carriers where stainless would corrode.
Pick the PTFE centrifugal impeller (IPS2050-P-T2) when:
- Workflow involves dissolving solids into aggressive-solvent liquid carriers (DMSO, DMF, halogenated solvents)
- Acid / base reagent dissolution in strong-acid / strong-base liquid (concentrated HCl, NaOH)
- Oxidizing-chemistry surfactant / emulsion prep at the 5β40 L pilot batch scale
- Workflow is radial-flow dissolution at chemical-resistance-required scale
Pick the stainless equivalent (IPS2050-P-S2) for aqueous / mild-solvent / neutral-pH dissolution workflows.
Stainless vs PTFE Decision Framework
| Sample chemistry | Material | SKU | List price |
| Aqueous, mild solvents, neutral-pH, food-grade | Stainless | IPS2050-P-S2 | $172.00 |
| Aggressive solvents, strong acid / base, oxidizing | PTFE | IPS2050-P-T2 (this product) | $172 |
The $62 premium ($172 vs $172.00) reflects PTFE manufacturing cost, same flow pattern, geometry, and chassis compatibility.
IPS2050 PTFE Family Flow-Pattern Comparison
| SKU | Geometry | Flow pattern | Best for |
| IPS2050-P-T1 | One-line | Axial | Aggressive-chemistry particulate suspension |
| IPS2050-P-T2 (this product) | Centrifugal | Radial | Aggressive-chemistry dissolution / solution prep |
| IPS2050-P-T3 | Paddle w/flat holes | Mixed turbulent | Aggressive-chemistry high-viscosity |
| IPS2050-P-T4 | 4-arm | High-coverage axial-radial | Aggressive-chemistry workhorse |
All four PTFE variants priced identically at $172. Geometry choice is workflow-driven, not cost-driven.
Application Profile
Aggressive-solvent dissolution workflows. Dissolving high-mass solids into DMSO, DMF, halogenated solvents at the 5β40 L pilot scale.
Strong-acid and strong-base solution prep. Concentrated mineral-acid and strong-base reagent dissolution where stainless would corrode.
Oxidizing-chemistry surfactant prep. Peroxide-bearing or oxidizing-agent-bearing emulsion preparation.
Pharmaceutical formulation with aggressive ingredients. Semi-solid formulations including reactive cosmetic-class ingredients (salicylic acid, glycolic acid, retinoid systems).
Industrial-process aggressive-chemistry feed prep. Process-development workflows involving aggressive solvent or acid feed streams.
Cosmetic and personal-care reactive-ingredient formulation. Formulation development with reactive ingredients incompatible with stainless steel.
Ordering & Configuration
Pair with chassis. Confirm OS-20L (IPS2050-20 / -20-E) or OS-40L (IPS2050-40 / -40-E) chassis inventory at order.
Pair with PTFE family for full chemical-resistance coverage. Labs running diverse aggressive-chemistry workflows benefit from inventorying multiple PTFE geometries.

IPS2050 PTFE / Teflon impeller selection:
- IPS2050-P-T1 (One-line, axial) aggressive-chemistry particulate suspension
- IPS2050-P-T2 (this product): Centrifugal, radial, aggressive-chemistry dissolution / solution prep
- IPS2050-P-T3 (Paddle w/flat holes, mixed turbulent) aggressive-chemistry high-viscosity
- IPS2050-P-T4 (4-arm, general-purpose) aggressive-chemistry workhorse
Pick the PTFE centrifugal impeller for radial-flow dissolution in aggressive-chemistry conditions; stainless equivalent (IPS2050-P-S2) covers aqueous / mild-solvent dissolution at lower price point.
