What is the LABWIT ZWY-100D?

The ZWY-100D is a 63 L benchtop orbital shaking incubator from LABWIT. It combines temperature-controlled incubation and orbital shaking in a single compact laboratory instrument.

The system is intended for small- to medium-capacity laboratory workflows requiring controlled:

• Temperature.
• Incubation time.
• Orbital agitation.
• Shaking speed.
• Orbital stroke.

The ZWY-100D is a heating-only model with an operating temperature range from approximately ambient temperature +5 °C to 60 °C.

Its high-speed drive system enables shaking speeds from 30 to 600 rpm, making the model particularly suitable where compact vessels and relatively high agitation speeds are required.

High-Speed Orbital Shaking up to 600 rpm

The ZWY-100D uses an orbital shaking mechanism with an adjustable speed range from 30 to 600 rpm.

This relatively wide speed range allows the instrument to accommodate different vessel sizes and agitation requirements within the limits of the installed tray and flask configuration.

A specialized low-noise induction motor system enables operation at speeds of up to 600 rpm while maintaining smooth orbital movement.

Brushless AC Induction Motor

The shaking mechanism is driven by an AC induction motor that is:

• Brushless.
• Designed for low-noise operation.
• Suitable for extended laboratory operation.
• Maintenance-free under normal operating conditions.

This design is useful for shaking incubators because biological incubation procedures may require long periods of continuous agitation.

Continuously Adjustable Orbital Stroke from Ø1 to 50 mm

A distinctive feature of the LABWIT ZWY-100D is its ability to adjust the orbital shaking diameter continuously from Ø1 mm to Ø50 mm.

Rather than being restricted to a single fixed orbit, the user can adapt the shaking stroke according to the vessel size and experimental requirements.

This provides additional flexibility when switching between different types of laboratory vessels and shaking conditions.

Why Does Orbital Stroke Matter?

The orbital diameter influences liquid movement inside the vessel. Together with shaking speed, vessel geometry and working volume, it determines the agitation conditions generated during incubation.

The adjustable stroke therefore allows laboratories to optimize the mechanical shaking conditions for different workflows without requiring a separate shaker for each orbital diameter.

Precise Temperature Control for Laboratory Incubation

The ZWY-100D uses microprocessor-based temperature control to maintain stable incubation conditions.

Key temperature specifications include:

• Temperature range: ambient +5 °C to 60 °C.
• Temperature accuracy: ±0.1 °C.
• Temperature uniformity: ≤ ±0.5 °C at 37 °C.

The controlled airflow inside LABWIT shaking incubators is designed to distribute temperature throughout the chamber and maintain homogeneous incubation conditions.

Heating-Only Configuration

The ZWY-100D is an Economic Series heating-only shaking incubator. Its minimum controllable temperature is therefore approximately 5 °C above the ambient laboratory temperature.

For applications requiring operation below ambient temperature, a refrigerated LABWIT shaking incubator should be selected instead.

Durable and Easy-to-Clean Laboratory Construction

The ZWY-100D is designed for frequent laboratory use with surfaces intended to simplify cleaning and routine maintenance.

Stainless-Steel Interior

The inner chamber and shaking tray are manufactured from electro-polished stainless steel.

This provides a smooth working surface that is suitable for routine laboratory cleaning.

Tempered Observation Glass

A tempered glass observation window provides clear visibility of the shaking chamber, allowing operators to check samples without unnecessary interruption of the incubation process.

Compact Benchtop Format

The external dimensions are approximately:

• 600 mm wide.
• 580 mm deep.
• 520 mm high.

This allows the 63 L shaking incubator to be installed directly on a laboratory bench while still providing a usable tray area of 340 × 370 mm.

Microprocessor Control, LCD Display and Safety Functions

The operating parameters of the ZWY-100D are managed through a microprocessor-controlled interface with a large LCD display.

The screen displays both:

• Programmed operating parameters.
• Actual measured operating parameters.

This allows users to monitor temperature, shaking and timer settings during operation.

Password Protection

Password protection can be used to prevent unauthorized changes to operating parameters.

This feature can be particularly useful in shared laboratories where several operators have access to the same incubator.

Audible and Visual Alarms

The system provides audible and visual alarm functions for conditions including:

• Over-temperature conditions.
• Motor overheating.

These alerts help the operator identify abnormal operating conditions promptly.

Soft Start After Lid Opening

After the lid has been opened and closed, the shaker uses a soft-start function and smooth acceleration rather than returning instantly to full shaking speed.

This helps reduce sudden mechanical movement of the vessels and liquid samples.

Timer and Continuous Operation

The integrated timer can be programmed from 0 to 9999 minutes.

For protocols requiring longer operation, the ZWY-100D can also be used in continuous mode.

This allows the same instrument to support both defined-duration incubation protocols and extended shaking processes.

Flask and Vessel Capacity

The standard shaking tray measures 340 × 370 mm. Depending on the installed clamps or holders, the ZWY-100D can accommodate multiple flask sizes and laboratory vessels.

*Actual maximum capacity can vary according to flask dimensions, manufacturer, clamp type and tray configuration.

Applications of the LABWIT ZWY-100D Shaking Incubator

The combination of controlled heating and orbital agitation makes the ZWY-100D suitable for laboratory workflows involving the growth and incubation of biological materials under controlled shaking conditions.

Typical application areas include:

• Microbiology laboratories.
• Molecular biology laboratories.
• Biotechnology research.
• Life science research.
• Biological culture workflows.
• Routine shaking incubation.
• Sample preparation requiring controlled orbital agitation.
• Research and teaching laboratories.

Culture Flask Incubation

The system can accommodate multiple Erlenmeyer flask sizes from small 50 mL vessels up to 1000 mL flasks, depending on the selected clamp configuration.

Tube-Based Workflows

Optional stainless-steel or plastic tube racks can be installed for workflows requiring multiple tubes to be shaken under controlled temperature conditions.

Microplate Shaking

With the appropriate plate clamps, the ZWY-100D can accommodate up to four 96-well plates.

• 250 mL.
• 300 mL.
• 500 mL.
• 750 mL.

Why Choose the LABWIT ZWY-100D?

When Should You Choose the ZWY-100D?

The LABWIT ZWY-100D is particularly suitable for laboratories that require:

• A compact benchtop shaking incubator.
• A chamber volume around 63 liters.
• Orbital shaking speeds up to 600 rpm.
• Flexible orbital diameter adjustment.
• Incubation temperatures above ambient temperature.
• Accurate and uniform temperature control.
• Compatibility with multiple flask sizes, tubes or microplates.
• A practical economic-range system for routine laboratory operation.

Because the ZWY-100D is a heating-only model, laboratories requiring incubation below ambient temperature should consider a refrigerated LABWIT shaking incubator instead.
