Basic
- Pump - Valve - Detector
Manual sample introduction
The “Basic” configuration is the most no frills and affordable HPLC system whilst fully optimized for educational institutions.
The perfect solution when only small numbers of samples need analysis.
Basic Automated
- Autosampler - Pump - Detector
Autosampler Injection
'Replacing valves with an autosampler allows automated analysis. This is a great setup when multiple analyses of the same type need to be carried out labor un-intensively.

Gradient Automated
- Two Pumps - Autosampler - Detector
A laboratory workhorse, holds up to 48 samples or 96 wells
The “Gradient automated” configuration has 2 pumps to enable the delivery of gradient solvents.
This setting is intended for laboratories, universities and R&D departments. It will run several analyses via different methods.
Gradient Automated Flip
- Valve - Two pumps - Autosampler - Detector
Two-column automated analysis for bio samples.
The “Gradient Automated Flip” setting has an additional valve. It is our most advanced HPLC system.
This enables FlipLC functions or column switching capabilities.
Configurations available for all sorts of analysis.

Alltesta Mini

Complete functionality in a single unit
Offering small size, simplicity, and power to do most chromatography tests when automation is not required.

Alltesta Mini is the perfect analytical tool for education, onsite testing, monitoring production operations, and testing products in a small business setting when the lab is not available.

Easily upgrade your Mini with an additional pump and switching valve. If automated injection becomes required, you can upgrade the Mini by simply adding on our Alltesta Autosampler. If your product is not detectable by a UV detector, any other detector with an analog output can be supported.

Autosampler

The Autosampler Frees Up Time and Handles Accuracy
Compact autosampler has the capacity to hold 48 standard 2.0ml vials or 96 wells plate to automate routines. This is fully integrated into the hplc.cloud software, available from any place at any time

Inexpensive and reliable automation for any analytical and liquid handling instrument. Comprehensive control with direct access to all of its features. Build a sequence, control injection order and assign a method to each sample.

Pump

The Syringe Pump Delivers Pulseless Liquid Flow
Designed for nearly every modern application that involves accurate flow metering. Suitable for diverse chemical and biomedical research areas where precise solvent dosing is required

The syringe method of solvent delivery solves most problems associated with reciprocating pumps. Stable pulseless flow at any pressure. No solvent degassing required. Flow stability does not depend on the check valve performance. The pump is highly durable due to requiring one plunger stroker per analysis. Boasts a wide range of flow rates and fast refill times.

There are two important advantages of a Gradient Alltesta system
The solvent gradient is formed with zero dead volume on the high-pressure side
Two syringe pump design eliminates the need for a solvent mixer and a pulse dampener

Valve

Our High-pressure
Switching Valve
Expands Opportunities
The Alltesta high pressure, high speed switching valve allows for several flow paths switching under high pressure

In a most affordable “Basic” setup, this valve eliminates the need for an autosampler by employing a fixed-volume injection loop and a manual syringe for sample introduction. Valve in “Flip” setup enables sample cleaning or column-switching for R&D purposes.

Detector

The Detector Sheds Light
on the Analytes
The Alltesta UV/VIS Detector is designed to continuously monitor the optical characteristics of the flow with up to 4 wavelengths simultaneously. The LED driven light source has zero warm up time along with great durability

To eliminate bubble formation in the detector cell, we included a built-in back pressure regulator. The typical application is HPLC, but other applications such as Flow Injection Analysis (FIA) and preparative & flash chromatography can also be utilized.
The Detector cell is replaceable and available in two versions, 3 μL and 10 μL in volume.
