What Omnitek does

Omnitek B.V. is a Netherlands-based, family-owned manufacturer of automated kinematic viscometry systems founded in 1979 by Willem Wagelaar (originally as Wagelaar Glass Instruments) and headquartered in Waddinxveen. The company designs, builds, and services bench-top and floor-standing viscometers that measure the kinematic viscosity of petroleum products, lubricants, used oils, and other fluids, serving QC, R&D, and used-oil-analysis laboratories across petroleum refining, lubricant manufacturing, petrochemicals, industrial condition monitoring, contract testing, and academia. Its product range comprises three core platforms: the Houillon-based S-flow IV (and S-flow IV+) series optimized for high throughput (up to 80 samples/hour) with sub-1 ml sample consumption, the U-Visc series offering full ASTM D445/446 compliance with carousel autosampling, and the Ubbelohde-based BitUVisc series designed for highly viscous and opaque samples up to 120,000 mm²/s at elevated temperatures. A Cartesian-robot Cito autosampler, launched in 2021 and refreshed in 2024, can service one or two S-flow IV systems for fully unattended operation.

Omnitek's underlying technology centers on Houillon-style and Ubbelohde viscometer tubes paired with optical or thermal meniscus-detection sensors, temperature-controlled baths with ±0.02°C stability, and modular bath/tube/automation configurations that allow field upgrades. Systems are sold via a quote-based, configuration-driven model, complemented by preventive-maintenance and repair service contracts delivered through a global network of trained distributors plus direct sales from the Netherlands. The go-to-market combines direct enterprise sales, an online demo room for live product presentations, and industry visibility through events such as OilDoc and trade publications like Petro Industry News. Pricing is not publicly disclosed, but the modular architecture and ASTM-compliance positioning support a premium, niche-specialty positioning in the global analytical instrumentation market.

Core offering

Omnitek designs and manufactures automatic kinematic viscometry systems for laboratories that measure the viscosity of petroleum products, lubricants, used oils, and highly viscous fluids such as heavy fuel oils, asphalts, crude oils, and waxes. Its product range covers three platform families (S-flow IV+, U-Visc, BitUVisc) plus an automated Cito autosampler, all configured to support ASTM-compliant testing, minimal sample consumption, and unattended high-throughput operation.

Product overview

Omnitek is a viscometer manufacturer offering three main product lines: the S-flow IV+ series based on Houillon design for maximum throughput with less than 1ml sample; the U-Visc series compliant with ASTM D445 for broad-range viscosity testing; and the BitUVisc series for highly viscous samples up to 120,000 mm2/s. All systems can be combined with the Cito autosampler for fully automated unattended operation. The company provides tailor-made solutions for various lab applications ranging from QC to R&D for used/new oil analysis.

Products and services

• S-flow IV+ Viscosity Meter Houillon kinematic viscometry system with 2 baths and 2 tubes each, throughput up to 80 samples per hour, 0.3–1.0 ml sample volume, ASTM D7279 compliant and correlated to ASTM D445, with 12-inch capacitive touchscreen and optional Cito autosampler compatibility. Designed for petroleum product QC, R&D, and used oil analysis laboratories needing high-throughput, low-solvent operation.
• Cito S-flow IV Autosampler Cartesian robot autosampler that services one or two S-flow IV systems simultaneously with 8-tube capacity, 80 injections per hour at 2 temperatures, up to 384 samples per run, and 8–12 hours of unattended operation. Targeted at laboratories running high sample volumes or needing overnight, walk-away viscosity testing.
• U-Visc Viscosity Meter Fully automatic kinematic viscometer using Ubbelohde tubes, fully compliant with ASTM D445/446, with vacuum or pressure sample introduction, carousel autosampler for 16 samples per tube, single or dual bath configurations, and a measurement range of 0.15–25,000 mm²/s. Suited to QC labs, R&D, used oil analysis, and contract testing laboratories requiring ASTM D445 reference-method compliance.
• BitUVisc Viscosity Meter Fully automatic viscometer based on the Ubbelohde design with thermal sensors for detecting opaque fluids, supporting viscosities up to 120,000 mm²/s at temperatures up to 150°C, integrated sample heating up to 200°C, and preheated solvent cleaning. Configurable in multiple bath and tube counts, aimed at petrochemical, asphalt, heavy fuel oil, and specialty chemical laboratories.
• Service and Support Contracts Preventative maintenance, on-site and remote repair services, and instrument service contracts delivered by Omnitek's technical service department and trained distributor partners. Targeted at laboratories owning Omnitek viscometers that require ongoing uptime assurance, spare parts, and calibrated performance.
