產品簡介

STB-140,Strexcell細胞牽張拉伸系統,b-bridge細胞牽張拉伸系統

詳細介紹

STREXS是一種模擬細胞生長過程中機械應力的裝置。張力腔室中的細胞被儀器拉伸或壓縮。施加在細胞上的機械應力更好的模擬了自然動態(tài)生理環(huán)境，可精準控制施加在細胞上的應力級別。

Cells Stretching System

Manual Stretch System(for trials) STB-10

Stretching culture system of manual type

Conduct stretching/compression manually. Please use this system for evaluation purpose of automatic stretching systems(e.g. STB-140) before installation.
Users can share the chambers with STB-140.
Two models available in accordance with chamber sizes.

System Configuration	System Specification
STB-10-04(for 4cm²) STB-10-10(for 10cm²)	Stretching ratio: up to 20%, 0.5mm stretching a turn of the dial(2.5% of stretching ratio for STB-10-04, 1.6% for STB-10-10). Note: Conduct culture putting the system into a culture dish. Stimulation direction: uniaxial

Automatic Stretch System STB-140

Standard system with high versatility

The system has functionality to load stretching stimulation on cells while culturing them in CO² incubator.
● Functionality to stimulate multiple chambers simultaneously makes it easy to compare between samples.
● Install the main unit within CO² incubator, the controller outside.
● Stretch chamber mounting unit is removable, so users put it into clean bench and conduct aseptic work.
Preprogrammed one-chip microcomputer is embedded in the controller. While operation, users choose the stretching ratio and stretching frequency with DIP switch on the controller, and make the main unit to generate the desired stretching pattern.
The controller also has the functionality to control the water flow for refrigeration of the motor in the main unit.

Stretch System for Microscopes STB-150

Installable on microscope stage

Enables to observe morphological changes and ionic behavior in real time, under stretching stimulation.
Install the main unit of the stretching system on microscope stages to load automatic stretching stimulation with the controller.

System Configuration	System Specification
Main unit: normal type is compatible with Nikon, Olympus(compatibility with Zeiss and Leica is optional) Controlling unit: controls stretching patterns.	Compatible with 4cm² chamber Stimulation direction: uniaxial Stretching patterns: up to 64 patterns Stretching Stimulation Loading is up to 20 minutes continuously. (The system is without motor refrigeration unit. Long period operation results in the overheat of the motor. Use STB-140 for long period, continuous stimulation loading.)
