The high speed micro-centrifuge is widely used for specimen preparation in molecular and cellular biology.
The centrifuge can also be used in high end research applications such as sedimentation of cells and viruses and separation of sub-cellular organelles.
The micro-centrifuge features a 24 x 1.5/2.0ml rotor made from high strength aluminium which is fully autoclavable. 
The rotor has an anti-sample overflow which ensures tubes do not leak during the process and cause microbial contamination.  
Four different rotors are available and smaller 0.5/0.2ml tubes can be used with adapters.  
The high quality cast casing gives stability, reliability and noise reduction throughout the process. 
The centrifuge will spin from 200 – 15000rpm and can be controlled in 10rpm increments.
A user friendly LCD screen allows running information including both RPM and G force to be displayed easily. 
The running of the centrifuge can be timed between 30 seconds and 99 minutes or can be used in continuous mode.  
The timer only starts when the desired speed is reached to ensure accurate separation time. 
The centrifuge also has a ‘short spin’ function which can be operated by pressing and holding the ‘Pulse’ button. 
This allows the centrifuge to be accelerated and held at the target speed. 
The lid of the laboratory centrifuge automatically releases when the rotor stops to save processing time.  
The lid also has a dual interlocking design for safety.

Two unique features on the Micro-Centrifuge are:
Special multi-flow air cooling system to help keep the rotor temperature low
Temperature displays allows sensitive samples to be protected from damage

This spare water bath kit is specifically designed for use with the Nanoheat Hotplate, providing a convenient replacement or additional accessory for laboratory heating applications. The kit allows efficient conversion of the hotplate into a water bath setup for controlled heating tasks.

Please note that the image is representative of the range only. The hotplate is not included with this kit and must be purchased separately

The Professional Cork Borer Set by PSAW India is an essential tool for any chemistry or biology laboratory. This comprehensive set of 15 various-sized punches is engineered for precision and longevity. As a leading Laboratory Equipment Manufacturer in India, we ensure each borer meets global research standards.

This Double Walled Serological Water Bath is designed for uniform heating and reliable temperature control for routine laboratory applications. The inner chamber is made of SS 304 grade stainless steel, ensuring excellent corrosion resistance, hygiene, and long service life. The outer body is constructed from mild steel with powder coating or stainless steel, providing strength and an attractive, durable finish.

The space between the inner and outer walls is filled with high-quality glass wool insulation, minimizing heat loss and improving energy efficiency. The inner chamber is fitted with an immersion type heating element, which ensures fast heating and uniform temperature distribution across the bath.

Temperature is regulated by a hydraulic capillary thermostat, allowing smooth control from ambient to 100°C with an accuracy of ±1°C, making it suitable for serological, incubation, and general laboratory heating tasks. The unit operates on a 220/230 Volt AC power supply, ensuring compatibility with standard laboratory electrical systems. Multiple circular holes are provided on the top surface for convenient placement of test tubes, flasks, or bottles.

• This simple piston disc and cylinder form a dash-pot damper that fits to the guide rods under the platform. 
• It works with easily found non-toxic fluids for different damping levels. 
• Students may try their own fluids and their own piston discs for project work. 
• When using the Damper Kit, VDAS can fit its displayed data to underdamped and overdamped viscous damping models. 

• The module consists of a fan and instrumentation, all mounted on a robust, mobile trolley for ease of use. 
• The Universal Dynamometer measures the speed, torque and power absorbed by the fan. 
• Speed is fully variable up to the maximum allowable for the fan. 
• Slide-valve controls the airflow rate. The fan impeller is interchangeable. 
• Air enters the fan through a shaped nozzle, used to measure the airflow rate. 
• Air then moves past a slide-valve and out to atmosphere. 
• The fan housing has an interlock so the motor cannot run unless the user assembles the fan correctly. 
• This allows the user to safely change fan impellers. 
• Supplied with the fan are three different impellers for more tests on fan performance.

This laboratory instrument is a mains-operated digital photo colorimeter designed for measuring the Optical Density (OD) or absorbance of solutions. It features a bright, easily readable 2½ Digit LED display and operates across the visible spectrum with a wavelength range of 400 to 700 nm. The output provides OD readings from 0 to 1.99, offering a high resolution of 0.01 OD and an accuracy of 0.5% FSI. The instrument is highly efficient with sample usage, requiring a minimum solution volume of only 1 ml for accurate measurements. Power is supplied via a standard 230 V $\pm 10\%$, 50 Hz, AC input.

The core photometric system utilizes a Selenium Photocell as the detector and a 6.8 V, 300 mA lamp as the light source. It comes equipped with five standard glass filters, allowing measurements at specific wavelengths: 420 nm, 480 nm, 540 nm, 620 nm, and 680 nm. The unit is ready for immediate use and includes essential accessories such as a set of five test tubes, a spare lamp, a protective dust cover, and a comprehensive instruction manual. This colorimeter is an excellent choice for general chemical and biochemical laboratory applications requiring accurate, low-volume photometric analysis.

The Static Pass Box is a device designed to restrict the transfer of materials between cleanrooms or controlled environments, minimizing personnel movement, in order to maintain contamination control. It prevents airborne contamination that would otherwise create obstructions to clean transfer operations. For this reason, it is essential in such industries as pharmaceutical, biotechnology, and electronics.

As a leading Plant Growth Chamber Manufacturer, we design and manufacture precision-controlled chambers for plant research, cultivation, and experimental studies.
