Biological Respirometer with Stand

The Biological Respirometer with Stand is a biology laboratory apparatus used for investigating oxygen uptake during cellular respiration. Designed for supervised school, college, university, and teaching laboratory experiments, it enables students to observe and compare respiration in suitable living specimens while learning how gas-volume or pressure changes relate to metabolic activity.

Product Description

The STEMAids Biological Respirometer with Stand is intended for practical investigations of aerobic respiration. A respirometer operates as a closed experimental system in which oxygen consumption by a respiring specimen produces a measurable change when carbon dioxide is appropriately removed according to the experimental method.

The supporting stand is intended to hold the apparatus in a stable working position during observation. Exact chamber capacity, construction material, manometer or capillary configuration, graduation range, dimensions, and supplied accessories for this STEMAids model require confirmation before publication. Related equipment is available under biology lab products and general laboratory products.

How to Use the Biological Respirometer with Stand

1. Position the respirometer securely on its stand.
2. Prepare the biological specimen and control according to the approved practical protocol.
3. Add the specified carbon dioxide absorbent only if required by the chosen experimental method.
4. Assemble and seal the apparatus as directed, ensuring connections are airtight.
5. Allow the apparatus to equilibrate under the selected experimental conditions.
6. Record movement or readings from the measuring system at defined time intervals.
7. Calculate or compare oxygen uptake using the method specified in the laboratory protocol.

Safety note: Some respiration protocols use potassium hydroxide or soda lime to absorb carbon dioxide. These materials require appropriate PPE, supervision, and chemical-handling procedures. Keep absorbents physically separated from living specimens.

Care & Maintenance

• Clean the apparatus after each practical using a method compatible with the confirmed construction material.
• Inspect tubing, stoppers, seals, and connections for leakage or damage before use.
• Handle measuring tubes and other fragile components carefully.
• Store the clean, dry apparatus securely with the stand to protect measuring components.

Frequently Asked Questions

What is a Biological Respirometer with Stand used for?

It is used to investigate respiration by monitoring changes associated with oxygen consumption by a living specimen in a closed experimental system.

Can a respirometer measure oxygen uptake?

Yes. When carbon dioxide produced during respiration is appropriately absorbed, the resulting change in gas volume or pressure can be used to determine oxygen consumption.

What organisms can be used in a respirometer experiment?

Teaching experiments commonly use actively respiring specimens such as germinating seeds or suitable small invertebrates. The chosen specimen should follow the approved laboratory protocol and ethical requirements.

Can students investigate the effect of temperature on respiration?

Yes. A respirometer can be used to compare respiration at different temperatures when experimental temperature is controlled and other variables are kept consistent.

What material is the STEMAids respirometer made from?

The construction material of this specific model is [confirm]. It should not be described as borosilicate glass or any other material until verified from the STEMAids specification.

Is the Biological Respirometer suitable for schools?

Yes. The apparatus is relevant to supervised biology practical work involving respiration, gas exchange, experimental controls, and quantitative observation.
