Column oven is important to achieve better temperature stability of HPLC columns by analysis.
Using it we get:

• Better reproducibility
• Higher separation performance
• Reduced analysis time

Range of temperature regulation is from ambient temperature up to 99°C. Actual oven temperature is shown on display. Temperature stability is ± 0.1°C. 
This unit is great at its small dimensions. The heated part is separated from the controlling unit, allowing it to be easily installed in a chromatography configuration. 
Setting the required temperature is also made simple by means of arrow buttons and storing. After the unit is turned off, the oven retains the last used temperature in memory and thus there is no need to reenter it during repetitive analyses.
An independent safety circuit turns the heater off and transmits an acoustic signal when the set temperature is exceeded by 10°C

Concentrating of samples is widely used in combination with solid phase
extraction (SPE) in analyses of environmental samples (determination of polycyclic aromatic hydrocarbons, biphenyls, chlorophenols, pesticides, etc.). It is used method of concentrating dissolved samples by solvent evaporation using introduction of controlled gas flow above the level of the solution with temperature control.

Main features:

• simultaneous treatment of up to twelve samples
• gas supply to each vial equipped with a valve
• easy handle
• height adjustable gas distribution part
• usually are used 10 ml reactions vials with conical bottom (P/N: 099451)
• for smaller and non standard vials are supplied reductions
• Termovap is equipped by safety fuse „ +10°C "
• unit is controlled by keyboard or using RS232
• concentrating with temperature control and gas introduction above solution surface

This is a sample concentrator used for concentrating up to 12 samples simultaneously by the evaporation of a solvent by blowing a controlled flow of gas over a solution surface at ambient temperature. Vials are located in a stand manufactured according to each customer's individual request; there is also a valve and a needle above each of the vials serving as the gas inlet. Distribution of gas is height adjustable and can easily be connected to the reduction valve of a gas cylinder by silicon tubing.

10 ml Reaction Vials
Reaction vials with thick walls, a cone bottom and graduation, PTFE-silicon sealing and open-hole threaded caps. They are designed for Termovaps.

5 ml Reaction Vials
Reaction vials with thick walls, a cone bottom and graduation, PTFE-silicon sealing and open-hole threaded caps. They are designed for Termovaps when using a reducing adapter P/N: 57050530.

Reducing Adapters to Termovaps
The reducing adapters make possible to use 5 ml reaction vials or other
vials or tubes with Termovaps.
