Pasteur Pipettes, LDPE
Unbreakable, non-toxic all-in-one pipettes eliminate the hazard of broken glass and exposure to infectious materials.
Molded from translucent low-density polyethylene they are inert to biological fluids and most acids.
Can be sealed and refrigerated.
The low-affinity, low binding surface reduces the loss of cells and valuable proteins.
Sterile and non-sterile options available.SKU: CH11622Pathological Microscope, Model 20208
This is a standardised microscope for medical institutions and pathological laboratories.
General Features
* Pressure die-cast parts to ensure strength and uniformity.
* Well proportioned stable, rigid and vertical body inclinable through 90°.

Eye Pieces : Huygenian x5, x10, x15 (any two)
Objectives : Achromatic x10, x40 (spring loaded) and x100 (spring loaded) oil immersionSKU: B10080PCR Tube Rack
This rack, as the name suggests, is used for keeping PCR tubes. Top & base of this rack are made of tough & transparent polycarbonate while the middle portion is made of Polypropylene. The tube holding spaces are uniformly placed so as to facilitate the use of multi-pipettes. A no. of racks can be stacked together to save shelf space.
SKU: CAC10350Pendulum Demonstration
This setup clearly demonstrates simple harmonic motion and the conservation of energy. In simple harmonic motion, pendulum swings evenly from side to side. Use photogate timer to accurately measure the period of the pendulum or the speed of the pendulum bob at the bottom of the swing. The length of the string can be adjusted to measure the change in period. Also see the effect of change in mass on the period. Two pendulum bobs are provided. Photogate Timer is not included.
SKU: PH10426Pendulum Waves
In this apparatus, you will use the laws of simple pendulum motion to create a pendulum wave apparatus: a device where many pendulums of different lengths, and therefore different periods, start swinging at the same time. As they move in and out of sync, the pendulums create a sequence of cycling visual wave patterns.
SKU: PH10420pH Meter
For measurements of pH values of homogeneous electrolytic solutions. Supplied with glass combination type of electrode, electrode stand & pH buffer solutions of 4 & 7 pH. The buffer solutions help in easy re-calibration of the pH meter. Standardization (7 pH) and slope (4 pH) adjustment controls are provided on the front panel. Detachable electrode ensures replacement convenience. Self check facility control on front panel enables users to ensure that the pH meter is functioning properly. Temperature setting on front panel provides compensation for different temperatures of solutions.
pH Range: 0 to 14.00 with resolution of 0.01 pH
Milli Volt Range: 0 to ± 1999 milli volts DC with resolution of 1 mV. pH or milli volt measurement selection is provided with a front panel control.
Accuracy: ± 0.04 pH for pH measurements, ± 2 for mV measurements
Temperature Compensation: 0 °C to 100 °C, settable with continuously adjustable front panel control.
Self Check Facility: Available with front panel control. Displays read 7.00 ± 0.02 pH to indicate proper functioning of the pH meter.
Re-Calibration: Front panel preset control of STANDARDIZATION enables calibration of 7 pH. Front panel preset control of SLOPE enables calibration of 4 pH. Buffer solutions of 4 & 7 pH are supplied with the pH meter to re-calibrate the pH meter.
Display: 3½ digit, 7 segment, bright LED type of 12.5 mm height. Decimal point, over-range and negative polarity indications are provided.
Power Requirements: 230 ± 10% V AC, 50/60 Hertz, 5 VA
