Complete Product Description

Is all you are doing, wipe tests? ...

You cannot go wrong with the Beckman LS 3801 Scintillation Counter

The Beckman LS 3801 Scintillation Counter can be operated in either a manual or automatic mode. Only the automatic mode is discussed. All racks following will be counted with the protocol defined by the first encountered command card. Counting will stop if the STOP protocol card is encountered. Usually this card is placed into a red rack but the color of rack is immaterial. If a rack is encountered with another command card, before the STOP rack, the new protocol will be used.

To edit user programs, select the appropriate user number after pressing the blue User Number key. While in this screen you may edit count time, sample repeat, select channel to count and set window.

Standard window settings, expressed in channel units are:

• Tritium 0-4000
• l125 0-567
• C13 0-670
• S35 0688
• P32 0-945 for samples in liquid scintillation media
• Cerenkov counting of P32 occurs at much lower energy and is usually counted on the H3 channel (0-400 channels) at an efficiency of about 45% in water.

This very compact benchtop unit is not only reliable, but is fully capable of all of your routine 3H, 14C, 32P assays as well as lab 'wipe tests'. The Beckman LS 3801 Scintillation Counter is a self-contained easy to operate unit.
