Common Laboratory Measuring Instruments and Their Uses
H.L. Scientific Industries—a leading Indian manufacturer specializing in precision‑engineered laboratory instruments.
1). Glassware for Volume & Liquid Measurement
- Beaker: A simple, cylindrical container with a flat bottom and a spout for pouring. It’s used for mixing, heating, and roughly measuring liquids. Common sizes range from a few milliliters to multiple liters.
- Graduated (Measuring) Cylinder: Tall, narrow cylinders marked with volume graduations for more precise liquid volume measurement than beakers.
- Pipette: Designed to transfer precise small volumes. Variants include volumetric, graduated, and micropipettes. Often used in quantitative analysis.
- Burette: A long, graduated tube with a valve (stopcock) at the bottom, enabling highly accurate dispensing of liquid—ideal for titration work.
- Flasks (Erlenmeyer, volumetric, round‑bottom): Used for mixing, heating, storing, or precise volumetric preparation of solutions, with reduced evaporation thanks to narrow necks.
- Test Tubes: Small glass tubes for holding, mixing, or heating small quantities of substances.
2). Mass, Weight & Time Measurement Instruments
- Analytical (or Digital) Balance: High‑precision scales used to measure mass, with typical accuracy down to 0.1 mg (0.0001 g). Crucial in quantitative chemistry for preparing reagents and standard solutions.
- Stopwatch/Timer: Essential tools for precisely measuring durations—important in kinetics, reaction times, or incubation periods.
3). Heat & Temperature‑Related Instruments
- Bunsen Burner: A gas‑fueled heat source for heating and sterilization. It’s flexible and widely used.
- Hot Air Oven: An insulated chamber for uniform heating, sterilization, or drying samples. Often equipped with digital temperature control.
4). Specialized Analytical and Biological Tools
- Microscope: Allows observation of tiny specimens; common types include compound and dissecting microscopes. H.L. Scientific offers models like the HL‑21 Series Binocular Microscopes.
- Centrifuge: Uses centrifugal force to separate sample components based on density—critical in biology, biochemistry, and clinical diagnostics.
5). Additional Laboratory Instruments
- Funnels: Standard or separating funnels used to transfer liquids or perform liquid-liquid separations.
- General-purpose and Support Equipment: Including hot air ovens, lab refrigerators, humidity cabinets, mortuary chambers, rotary shakers, among others.
