Vial loading trays

Single shelf loads can be stored, handled and ultimately slid on to this fence and tray accessory that is designed to maximize heat transfer by keeping the vial in direct contact with the shelf.

Bulk trays

Each stainless steel tray is capable of holding 2.5L of liquid. They are easy to clean, store and makes loading liquids very convenient.

Special feature

• Product Uniformity from top to bottom

• Product safety assured with accurate temperature control to ± 1°C

• Non-carcinogenic inert cooling fluid for operator safety

• Single phase operation without water cooling

• Includes vial stoppering under vacuum or inert gas

• Large shelf area (0.40m /4 ft ) from a small footprint

• Complete with full instrumentation for process optimization and

• pressure rise testing

Optional Accessories:

Isolation Valve; Bulk Trays; Spares Kit

Freeze Dryer Accessories

SS Column (T) Manifold  ( 8-Port or 24 – Port )

8-Port or 24-Port Column Manifold is useful for drying of small volume of liquids in flasks. It is provided with quick seal valves for holding flasks up to 1 litre capacity. Manifold sealing gaskets and cone connectors are also supplied with this accessory.

SS Drum Manifold (12-Port or 16-Port)

Stainless Steel Drum Manifold is available in 12 as well 16-Port versions. Each port is supplied with quick seal valve for holding flasks. Top and bottom manifold sealing gaskets are also provided. Drum manifolds are also useful for bulk drying in trays and beakers inside the drum.

8-Port Acrylic Drum Manifold

8 - Port Acrylic Drum Manifold can be used with all three models of Lyodel.Manifold sealing gaskets are also supplied with this accessory.

Spin Freezer

Spin Freezer is useful for freezing & primary drying of samples in glass ampoules. By spinning ampoules, samples are frozen on the base unit without the need for pre-freezing. The centrifugal force holds the liquid sample in position and prevents frothing and bubbling during evaporation as the sample solidifies and sublimes. The spin freezer has an independent power supply and includes a timer to prevent spinner overrun after freezing. Removable rotor plates provided with system accept 5 different sized ampoules.

Secondary Drying Manifold (24 – port or 48 – port  or 96 –port)

To complete the cycle and seal ampoules in the best possible condition, secondary drying manifold is used. 48-Port Manifold can be doubled to hold 96 ampoules by using the additional manifold supplied with a 'T' piece for connection.

Ampoule Sealing Torch

Simple hand held Ampoule Sealing Torch is useful for flame sealing freeze dried ampoules under vacuum in combination with secondary drying manifold. This Torch does not require conventional gas cylinders or long hoses.

Vial Stoppering Shelf

Using Vial Stoppering Shelf, samples in vials can be processed and stoppered under vacuum. The unit has movable aluminium shelves inside acrylic vacuum chamber. Each shelf accommodates two semicircular SS trays, removable for dualpurpose (vials as well as bulk) freeze drying. The vials can be moved together for stoppering under vacuum via a capstan.

Isolation Value

The basic function of this manually operated isolation valve is to isolate the drying accessory and sample from the ice condenser and pump. This is also useful in injecting inert gas before sealing the vials and for determining the dryness of the sample by measuring the vapour pressure in the drying accessory.

Bulk Drying Accessory ( Chamber, Racks & Trays)

The system has acrylic vacuum chamber with lid and upto five shelf rack assembly and trays. The acrylic vacuum chamber gives a clear view of the product and transmits radiant heat energy for drying. It is easily sealed by drop on acrylic lid with lead through for heater accessories. A conveniently designed rack supports up to 5 one litre stainless steel trays, and is ready wired to accept low voltage, heater pads under each tray. The design allows selection of any tray & heater combination for maximum utilization. It can be easily lifted in and out of freezer units. This system can also be used with temperature control unit for careful control of drying rate.

Heater Control Unit

The heater control unit is a freestanding power supply unit designed to deliver a thermostatically controlled low voltage power supply to the heaters. The heat energy produced by the heater mat under each shelf enhances the drying rate.
