Respirometer with Stand
Product Code : SCL-CLE-11904
The JLab India Respirometer with Stand is a precision-engineered biological apparatus designed to measure the rate of respiration in small organisms (such as germinating seeds, insects, or snails) by quantifying oxygen consumption. The system utilizes a closed-circuit design where carbon dioxide (CO2) is chemically absorbed, allowing the volume change in the manometer to directly reflect O2 uptake. This assembly includes a stable mounting rack, making it a critical tool for Physiology and Environmental Science laboratories.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Metabolic Interface: Facilitates student understanding of Cellular Respiration. Learners identify the conversion of chemical energy and the resultant gas exchange in living tissues.
- Gas Law Quantification: Enables the calculation of Oxygen Consumption Rate; learners apply the displacement of manometric fluid to calculateO2 volume per unit of time (ml/min/g).
- Comparative Analysis: Supports the analysis of "Respiratory Quotients" (RQ); students evaluate how different substrates (carbohydrates vs. Lipids) affect gas exchange by comparing CO2 production to O2
- Environmental Evaluation: Allows students to evaluate the impact of temperature on metabolic rates, observing how the rate of fluid movement in the manometer changes in response to thermal variables.
Functional Mechanics: The CO2 Absorption Principle
To ensure accuracy, a CO2 absorbent (typically Potassium Hydroxide (KOH) pellets or solution) is placed in the bottom of the chamber.
As the organism respires:
- Oxygen is consumed, reducing the internal gas volume.
- Carbon Dioxide is exhaled but immediately absorbed by the KOH.
- The resulting net decrease in pressure pulls the manometric fluid toward the specimen chamber, providing a direct reading of O2
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-density foam packaging. The U-tube manometer and glass chambers are nested in custom-cut inserts to prevent mechanical shock during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a detailed "Step-by-Step Lab Protocol" for instructors.
- Durability: The metallic stand is treated with an anti-corrosive finish, ensuring stability and longevity even in humid laboratory environments.
Direct OEM Sourcing Advantages
Procuring the JLab India Respirometer directly ensures vertical manufacturing control:
- Manometric Precision: Direct oversight of the capillary boring ensures a uniform internal diameter, which is essential for consistent fluid displacement readings across multiple units.
- Hermetic Seal Verification: We pressure-test every bung and joint assembly to ensure the system is 100\text{%} airtight, eliminating the "leakage error" common in budget respirometers.
- Direct Factory Inventory: Guaranteed availability of individual replacement glass chambers or U-tubes, allowing for cost-effective maintenance of lab inventory.
- Quality Assurance: Every scale is laser-etched into the glass to prevent fading from chemical exposure, ensuring the apparatus remains readable over years of use.
