Waveform Generator

1

MFG-2260 M

GW Instek, Taiwan

Waveform generators are versatile laboratory signal sources capable of producing standard and arbitrary waveforms such as sine, square, triangle, pulse, noise, and user‑defined signals over a wide frequency range. They typically feature fine frequency resolution, multiple modulation modes (AM/FM/PM/FSK), and PC/USB connectivity

3

Oscilloscope

1

GDS-1202B

GW Instek, Taiwan

Oscilloscopes are digital storage instruments designed to visualize, measure, and analyze electrical signals in time and frequency domains, with product lines covering bandwidths from about 50 MHz up to 500 MHz and sampling rates up to several GSa/s. They typically offer multiple channels, deep memory, automatic measurements, math/FFT functions, and PC connectivity

4

Stereo Microscope

1

STEMI-STEREO 2000C,

Carl Zeiss, Germany

Stereomicroscope is used for high‑quality stereo and zoom microscopes that provide crisp, three‑dimensional visualization of specimens with excellent depth perception, making them ideal for inspection and documentation of biological, industrial, and material samples

5

Compound Microscope

1

Magnus-MLX Plus, India

Compound microscope is used for routine research use, offering bright, high‑resolution imaging of stained and unstained specimens. They typically feature achromat or plan‑achromat objectives (4x–100x), Abbe condenser, wide‑field eyepieces, and stable mechanical stages with coaxial coarse and fine focusing, providing reliable performance for day‑to‑day microscopy work.

Gooseneck Illuminator

1

Onix India PVT Ltd- LED Fiver - Dual Probe, India

Gooseneck illuminator is a flexible external light source for microscopes that uses one or two bendable arms to direct intense, cool white light precisely onto the specimen. It allows adjustable angle and intensity, reducing glare and shadows and providing high‑contrast illumination for detailed observation and imaging in biological, industrial, and electronic applications.

7

Syringe Pump

1

Brain Tree Scientific, INC., USA

Syringe pumps are precision motor-driven devices that deliver controlled, pulseless flow rates of fluids from disposable or glass syringes, typically ranging from microliters per hour to milliliters per minute.

8

Vacuum Oven

1

Thermostable SOV-30 Daihan Scientific

South Korea

Vacuum oven is a specialized drying chamber that operate under reduced pressure to remove moisture and solvents from heat-sensitive materials at lower temperatures, preventing oxidation or degradation. They feature stainless steel chambers, precise temperature control (typically RT+10°C to 200–250°C), vacuum levels up to 99 Pa or -760 mmHg, and safety features like over-temperature protection for applications in pharmaceuticals, biotech, and materials science.

Chiller Unit

1

Srico-Daihan Scientific,

South Korea

Chiller unit is used to recirculate cooling systems that maintain precise low temperatures (e.g., -20°C to +100°C) for laboratory equipment like rotary evaporators or reactors, using compressors or thermoelectric cooling with pumps for continuous fluid circulation.

10

RF Plasma Cleaner

1

OSCE- RF 100, Omicron Scientific Equipment Co., India

RF plasma cleaner uses radio-frequency to generate plasma and remove organic contaminants, activate surfaces, or perform precise etching on samples like semiconductors, glass slides, or polymers. They operate in a vacuum chamber with gases such as oxygen or argon, breaking down hydrocarbons at the molecular level without damaging substrates, and are essential for microscopy preparation, microfabrication, and improving adhesion in biofilm or materials research.

11

Amber Desiccator

1

Lab Companion, South Korea

Amber desiccators are specialized laboratory storage cabinets made of UV-blocking amber glass or polycarbonate that protect light-sensitive samples from photodegradation while maintaining a dry environment via vacuum or desiccants.

12

Hot plate and Magnetic Stirrer

3

REMI, India

Magnetic stirrers featuring PMDC motors is used for stirring at high torque and stable speeds up to 1200–1500 RPM. It is designed for stirring volumes from 1–20 liters with hotplates for simultaneous heating.

Weighing Balance

2

ATY 224

Uni Bloc, Shimadzu, Japan

Weighing balance is used to measure mass accurately in research settings, with common types including analytical balances

14

Thickness Gauge

1

Mitutoyo, Japan

Thickness gauge is used to measure the thickness of a material, component, or coating, often with high precision down to the micrometer range. It is widely used in manufacturing, quality control, and research to verify that films, membranes, metals, plastics, and coatings meet specified thickness requirements without damaging the sample.

15

Micrometer Adjustable Film Applicator - 150 mm Width (Film casting doctor blade) EQ-Se-KTQ-150 Item No.: EQ-Se-KTQ-150

 

2

Hi-Tech, India

In materials and membrane research, a doctor blade or doctor-blade film applicator is commonly used to cast uniform thin films or tapes by dragging the blade over a substrate with a defined gap, which sets the wet film thickness.

16

Fume Hood

1

 

Fume hood is used to protect personnel from inhaling hazardous vapors, gases, and aerosols by capturing and exhausting contaminated air away from the breathing zone. Use of a chemical fume hood with a gas cylinder during membrane synthesis is essential to control exposure to toxic, volatile, or flammable reagents and to safely vent reaction by‑products.

17

Viscometer

1

J-Sil Scientific Industries, India

A viscometer is used to measure the viscosity of a liquid. It is essential in laboratories and industry to control solution/process behavior, coating quality, and reproducibility in formulations such as polymers, paints, oils, and suspensions.
