Analytical Glass Viscometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-BP-12565

The Analytical Glass Viscometer is a laboratory glass capillary instrument used for measuring or comparing liquid viscosity by timed flow through a narrow tube. It is suitable for school chemistry labs, college physical-chemistry practicals, analytical laboratories, science departments, distributors, and institutional procurement buyers.

Product Description

Analytical Glass Viscometer from School Equipments India is intended for supervised viscosity experiments in chemistry and physical science laboratories. It helps students observe how liquid flow time changes with viscosity, temperature, concentration, and fluid type.

A typical analytical glass viscometer uses a bulb-and-capillary arrangement with reference marks for timed flow measurement. Exact viscometer type, capillary constant, capacity, measuring range, glass type, calibration status, bath requirement, and certificate availability should be confirmed before publication, quotation, or tender submission.

Key Features

• Viscosity measurement support: used to compare liquid flow resistance through a glass capillary.
• Capillary-flow principle: suitable for timed-flow experiments with compatible Newtonian liquids.
• Analytical teaching value: supports lessons on viscosity, fluid flow, temperature effect, and physical chemistry.
• Manual observation method: students can record flow time and calculate viscosity using the approved formula.
• Glass apparatus format: allows clear visual observation of liquid movement between reference marks.
• Reusable laboratory glassware: can be cleaned, dried, inspected, and reused after compatibility checks.
• Specification-safe procurement: model type, capillary constant, calibration, and certificates must be verified before order.

How to Use the Analytical Glass Viscometer

1. Clean and dry the viscometer before use, and confirm that the capillary is not blocked.
2. Check the liquid compatibility, test temperature, and practical method before filling.
3. Introduce the liquid into the viscometer using the approved filling method.
4. Place the viscometer vertically in a suitable temperature-controlled bath if required.
5. Draw the liquid above the upper timing mark using a suction bulb or approved device.
6. Allow the liquid to flow naturally through the capillary under gravity.
7. Record the time taken for the meniscus to pass between the timing marks.
8. Repeat readings and calculate viscosity using the specified laboratory formula or calibrated constant.

Safety note: Never pipette by mouth. Wear suitable PPE, handle glass carefully, control liquid temperature, and follow the SDS for flammable, corrosive, volatile, or hazardous test liquids.

Care & Maintenance

• Clean immediately after use because residue inside the capillary changes flow time.
• Use only compatible cleaning solutions and avoid abrasive tools inside the glass tube.
• Do not force wire, needles, or hard probes through the capillary bore.
• Store the viscometer dry, vertical or cushioned, in a protected glassware cabinet or case.

Frequently Asked Questions

What is an Analytical Glass Viscometer used for?

An Analytical Glass Viscometer is used to measure or compare the viscosity of compatible liquids by timing flow through a glass capillary tube.

How does a glass capillary viscometer work?

A fixed volume of liquid flows through a narrow capillary under controlled conditions. The measured flow time is used with the approved formula or capillary constant to calculate or compare viscosity.

Is it an Ostwald viscometer?

The exact type is not confirmed. List Ostwald, U-tube, Ubbelohde, Cannon-Fenske, or any other model only after checking the final catalogue entry or quotation.

Does the viscometer come calibrated?

Calibration status is not confirmed. Claim a capillary constant, certificate, ASTM method suitability, or calibration traceability only if supplied with documentation.

Can students use it in school chemistry labs?

Yes. It is suitable for supervised school and college chemistry laboratories when teachers control filling, cleaning, temperature, timing, liquid selection, and glassware safety.

Why is temperature control important?

Viscosity changes with temperature. Reliable viscosity comparison requires the same controlled temperature for the test liquid, reference liquid, and repeat readings.
