1. INTRODUCTION
1.1 Introduction
The variable temperature thermal Sealer
4s2
is a semiautomatic instrument
designed to seal sample plates made from various polymers.
The sealer can be used with most plate types and sealing films available. Both
temperature and time are variable and can be optimised to suit each sealing
plate and film.
When the 4s2 is ready to start the operator needs to position the sample plate
together with a foil or film on the plate carrier. The sealing operation starts once
the drawer with the plate carrier has been closed. Film and sample plate will
then automatically be brought in contact with the heating element.
As soon as the sample plate is in contact with the heating element a countdown
timer starts and after the chosen sealing time the motor automatically moves the
sample plate away from the heating element and the operator can remove the
sealed sample plate for further processing.
