Cleaning agent for thermostatic chambers
First Claim
1. A method comprising:
- adding a cleaner into water provided in a thermostatic water bath for preventing generation of microorganisms and generation and attachment of air bubbles on the outer wall of a reaction vessel in the thermostatic water bath, and for producing no substances having absorption in the wavelength range of 300 to 900 nm in the water provided in the thermostatic water bath, the cleaner comprising;
a quaternary ammonium salt represented by the following general formula I and/or a preservative agent having amphoteric surface activity, and a surface active agent;

Abstract
[PROBLEMS] The present invention provides a novel cleaner having bacteria-proof, fungi-proof and algae-proof effects, which is added to a reaction thermostat using water as medium in scientific apparatus, particularly a thermostatic water bath in an automatic analyzer.
[SOUTLIN] A cleaner for a thermostatic water bath, which comprises a quaternary ammonium salt as shown by the general formula [1] described below and/or a preservative agent having amphoteric surface activity, and a surface active agent,
wherein R1 to R4 independently represent an alkyl group, provided that at least one among R1 to R4 is an alkyl group having 8 to 18 carbon atoms, and at least one among them is a lower alkyl group having 1 to 3 carbon atoms; and X− represents an anion derived from a carboxylic acid having two or more carbon atoms; and a cleaning method of a thermostatic water bath, wherein the cleaner is added to a thermostatic water bath.
