"tube+coolers"

Low voltage power supply with four outputs primarily intended to simultaneously supply power for the Teltron line of electron tubes and Helmholtz Coils, with four independent, adjustable DC voltages. The DC voltages are stabilized, regulated, floating, and galvanically isolated from one another, in addition to being short circuit proof and secure from external voltages.

Perfect tool for suspending a crucible.

Ideal for Nurses, PA's, and EMT's.

This lightweight polypropylene pump provides a constant vacuum when hooked to a standard faucet; it operates efficiently with water pressures as low as 7.5 psi for minimum water consumption. It has a maximum free-air pumping capacity of 11.5 liters per minute at a water-flow rate of 6.5 liters per minute. Ultimate vacuum: 28.5" Hg. Supplied with integral check valve, 3/8" NPT connecting thread, and 4 3/4" length of tubing for insertion in discharge end.

Economy blue hand vac pump for experiments in air pressure, vacuum filtration, and leak checks.

Student grade buret with fitted glass stopcock.

High quality thermal cyclers for laboratories with medium to high throughput needs.

The Air Core Solenoid is perfect for induced magnetic field studies.

Set up phlebotomy skills training stations.

Demonstrate the effect of pressure to water depth.

Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off, and power supplies for direct connection to light barriers. For event counting, a fixed counting period can be programmed in a range from 0.1ms to 99999s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.
