  Key Features

  • Hermetically Sealed: The dial is sealed with a glass or shatterproof polycarbonate window to prevent fogging and moisture entry.

  • External Reset: Most models include a calibration screw on the back, allowing for field adjustments to maintain accuracy over time.

  • Vibration Resistance: The bimetallic coil is dampened to ensure the pointer remains steady even in high-vibration industrial machinery.

  • Corrosion Protection: The stainless steel stem is designed to withstand harsh chemicals and high-pressure environments.

  Installation Guidelines

  Pro Tip: For high-pressure pipelines or corrosive fluid tanks, it is highly recommended to install the thermometer inside a Thermowell. This allows you to remove the thermometer for calibration or replacement without draining the system.

  Care & Maintenance

  • Calibration Check: Periodically test the unit using a "slush ice bath" ($0°C$) to ensure the needle aligns perfectly.

  • Cleaning: Keep the dial face clean of oil and soot to ensure readability. Use a non-abrasive cloth to prevent scratching the glass.

  Key Features

  • Digital Display: A clear 3-to-4 digit display ensures the set volume is always visible and easy to read during pipetting.

  • Ergonomic Grip: Designed with a finger rest to provide a secure grip, reducing hand strain during repetitive liquid dispensing tasks.

  • Low Pipetting Force: The internal spring mechanism is optimized for smooth plunger travel, minimizing the force required for both aspiration and blow-out.

  • Universal Tip Fit: The tip cone is precision-engineered to provide a leak-proof seal with most standard universal 200µl (Yellow) tips.

  • Durability: The body is resistant to common laboratory chemicals and UV light, ensuring a long operational lifespan.

  Performance Standards

  Calibration Note: Each EyeVent micropipette is calibrated in accordance with ISO 8655 standards. The accuracy ($A$) and coefficient of variation ($CV$) are tested using distilled water at 20°C to ensure the highest degree of reliability.

  Care & Maintenance

  • Storage: Always store the pipette in an upright position on a stand. To prevent spring fatigue, set the volume to the highest possible value (200µl) when the instrument is not in use.

  • Sterilization: Only the lower part of the pipette should be autoclaved. Ensure it is completely dry and cooled to room temperature before reassembling.

  • Seal Check: Regularly check the tip cone for cracks or wear to maintain the vacuum seal required for accurate volume delivery. 

• EyeVent Microscope  The EyeVent Ophthalmic Microscope is a high-precision surgical and diagnostic instrument designed for intricate eye procedures such as cataract surgery, corneal repairs, and retinal examinations. It provides superior depth of field and high-resolution imaging to assist surgeons in delicate microsurgeries.Technical Specifications

  • ENT & Training: Also suitable for basic ear examinations and medical student training in microsurgery.

  Maintenance & Safety

  Optical Care: Always use the dust cover when the microscope is not in use to prevent fungal growth on the lenses. Clean the optics only with specialized lens cleaning solution and a soft camel-hair brush or microfiber cloth.

  Safety Check: Ensure the floor stand brakes are firmly engaged before starting any surgical procedure to prevent accidental drifting of the microscope head. 

Vernier Calipers. 

EyeVent Binoculars are designed as versatile, high-clarity optical instruments suitable for both professional medical diagnostics (such as ENT or general examinations requiring slight magnification) and general-purpose outdoor use like birdwatching or surveillance.

• High-Power Optics: The 10x50 configuration is the "gold standard" for bright, clear images even in low-light conditions (dawn/dusk).

• BaK-4 Prisms: Uses premium Barium Crown glass which provides a perfectly round exit pupil and minimizes internal light scattering.

• Ergonomic Focus: Large, center-mounted focus wheel designed for smooth, precise adjustment, even while wearing gloves.

• Shock-Proof Build: The thick rubberized exterior protects the internal optical alignment from minor drops and rough handling in the field.

• Eye Comfort: Features twist-up eyecups and significant eye relief, making them comfortable for users who wear eyeglasses.

Optical Tip: Never use your shirt or a paper towel to clean the lenses as this can scratch the specialized FMC coating. Always use the provided microfiber cloth or a dedicated lens cleaning pen. When not in use, keep the objective lens caps on to prevent dust accumulation.

• Medical Field Use: Mobile health camps and quick visual assessments.

• Security & Surveillance: Clear identification of subjects at long distances.

• Nature Observation: High-detail viewing of birds, stars, and landscapes.
