57140- Ugo Basile Plethysmometer- Stoelting

Description

The first device designed specifically to measure paw swelling in rodents. More than 1000 bibliographic citations since 1960s! In research on rheumatoid arthritis, the central development of oedema, and its modifications by pharmacological processes, it has proved of great value to measure inflammatory oedema in the rat and mouse paw.

Overview

For accurate measurment of the rat and mouse paw oedema.

Features

• Direct connection to a PC via included software
• Multifunction graphic readout
• Printout from thermal printer (optional)
• Animal weight scale (optional)

The Ugo Basile™ Plethysmometer is a microprocessor-controlled volume meter that has long been the standard instrument for measurement of rodent paw volume.

The Basile Plethysmometer comes complete with the electronics block; a foot switch, an 18 mm water cell; a set of calibration volumes; a water reservoir; dust covers for the cells and electronics block; a bottle of wetting solution, and an operator’s manual. An optional thermal printer is available. Stand included.

Detail

GENERAL

In research on rheumatoid arthritis, the central development of oedema, and its modifications by pharmacological proc-esses, it has proved of great value to measure inflammatory processes in the rat paw.

Our Plethysmometer displays the exact paw volume on the graphic LCD read-out. Small differences are detected by a transducer of original design.

Plethysmometer The Plethysmometer is provided with a pedal holding-command which freezes the reading, enableing the operator to concentrate its attention to the paw dipping.

The paw volume is shown on the multifunction graphic display in four digits, with 0.01 ml resolution.

A zero key is provided to zero the meter before each measurement.

MEASURING WATER CELL

The measuring cell consists of two vertical interconnected Perspex tubes; the animal paw is dipped in the larger tube to measure displacement. A smaller tube is also included in the standard package, to be replaced on the water cell for measuring the mouse paw.

The smaller tube contains the transducer which measures the conductance between two vertical wire electrodes, com-pensating changes in conductivity brought about by salinity and temperature alterations.

DATA AQUISITION

The Plethysmometer is microprocessor controlled, fea-turing direct PC output. Internally-stored data can be routed to the PC serial or USB port (Sold separately).

Communication is managed by a Windows® based data acquisition software package.

This software enables the data storage into individual files, ready to be easily managed by most statistical analysis packages available on the market.
