The perfect hand-saving tool for inserting glass tubing into stoppers!

This apparatus determines hall voltage and coefficient.

The LaMotte ColorQ meter is a simple way to test low and high concentrations of chlorine.

A small centrifuge with lots of power.

Inexpensive, compact counter for measuring milliseconds (in conjunction with the free-fall apparatus 470162-756 ). Each count is started and stopped by a signal at the input sockets. The device is automatically reset to zero each time it is restarted. Includes plug-in power supply.

Build five different power supplies by connecting clip leads to one of the five color-coded terminals.

Tough vinyl lab aprons are resistant to lab reagents, acids, alkalis, oils, and grease.

Fast Enough for DNA Research, But Inexpensive Enough for Any Lab.

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.
