VirTis equipment

About VirTis

VirTis is an American manufacturer of freeze dryers and homogenizers, founded in 1953 by Charles E. Bender and Martin C. Parkinson in Yonkers, New York. It started out making homogenizers for life science research and later built its reputation on lyophilization equipment. The company is headquartered in Gardiner, New York, and is part of ATS Corporation, acquired through SP Industries in December 2021. Its range covers laboratory, pilot and production scale drying systems alongside its homogenizer line. Freeze drying is the work most of its catalogue does, and the maker's lines carry recognisable control and chamber conventions from the smallest benchtop unit upward. On Questpair the full range listed is used.

What freeze drying does in biotechnology?

Lyophilization removes water from a frozen sample by sublimation under vacuum, and that process sits at the centre of a large part of biologics work. Freeze dryers stabilise proteins, vaccines and other temperature-sensitive products for storage and transport, which places them squarely in bioprocessing and biomanufacturing workflows. A VirTis freeze dryer for protein formulation handles the drying stage after protein purification, where a liquid formulation has to become a stable solid cake without denaturing the active molecule. The same equipment supports cell culture and molecular biology labs that need to preserve reagents, standards and reference material. In molecular diagnostics and immunoassay production, lyophilized freeze dryers for vaccine and antibody preservation turn a wet formulation into a shelf-stable product, and a benchtop lyophilizer for small-batch research drying lets a formulation group test cycles before committing to pilot volumes. The homogenizer side of the business, including the VirTishear line, sits further upstream in sample preparation, breaking tissue and cells before extraction.

VirTis product lines

The freeze drying range is organised by scale and function. Genesis is the pilot and research shelf-based line, while AdVantage and AdVantage Pro are benchtop and small-pilot systems built around programmable recipes. The BenchTop and General Purpose Freeze Dryer names cover compact laboratory units, and Freezemobile is the manifold-style series for flask and ampoule drying. Ultra and Benchmark extend the range further, and VirTishear is the homogenizer line that traces back to the company's origins. Across these families the shelf area, condenser capacity and condenser temperature are the specifications that separate one model from another, and the right choice follows from the batch size and the product being dried rather than from the line name alone.

Which VirTis systems are listed on Questpair?

The Questpair catalogue holds 51 used VirTis items from 9 verified suppliers and distributors across 7 countries. Prices run from EUR 178 to EUR 178.359. The average sits around EUR 17.681, which reflects how far the range stretches between small units and complete production machines. 100 percent of the listings are used. Where a buyer needs a manual or documentation for an older unit, specialists reachable through Questpair respond within the hour, and replacement parts can be sourced via Questpair. Warranty is often possible and is arranged in consultation for the specific listing rather than applied as a blanket policy, so the sensible step is to read the individual listing for its stated condition and raise warranty on that unit directly. For anyone comparing a used system against a new one, the price difference is the clear distinction the catalogue records; everything else, from condition to support, belongs to the specific listing.

Questpair review of VirTis

Our take based on listings data and supplier feedback

VirTis occupies a specific place in the freeze drying market: a maker whose range stretches from a single benchtop unit to a pilot and production drying system, under one set of control conventions. That breadth is the first thing worth examining for anyone comparing options on the secondary market.

The scale span is the clearest practical benefit. A laboratory running small research batches can look at a BenchTop or General Purpose Freeze Dryer, while a group moving a protocol toward pilot volumes can look at the Genesis or AdVantage Pro lines without changing vendor conventions. Lyophilization is sensitive to shelf area, condenser temperature and condenser capacity, and matching those to the actual batch avoids both an undersized condenser that cannot hold the load and an oversized system that wastes money and bench space. Because the VirTis families share recognisable control and chamber design across sizes, a buyer who has run one model can read the specification of a larger one without relearning the instrument. On Questpair the listed systems span a wide price band, from EUR 178 at the accessory and small-unit end to EUR 178.359 for a complete production-scale machine, with an average around EUR 17.681.

The second benefit is the depth of the installed base. The Genesis, AdVantage, BenchTop and Freezemobile names have been sold for long enough that a used unit is rarely an orphan. That matters on the secondary market in a concrete way: when a question comes up about a manual or a replacement part, there is a documented history to work from. Through Questpair, documentation requests reach specialists who respond within the hour, and parts can be sourced via Questpair rather than left to the buyer to chase down. For an instrument that may be a decade or more old, that traceability is often the difference between a usable purchase and a gamble.

The third point is condition and price, and here the data is unambiguous rather than promotional. Every VirTis listing currently on Questpair is used. 100 percent of the listings are used. Used lyophilizers are listed at prices below the equivalent new systems, which is the one comparison the catalogue supports; it does not record warranty or support terms, and those are arranged in consultation for the specific listing rather than set centrally. A buyer weighing a used Genesis against a new one should therefore read the individual listing for its stated condition and ask about warranty on that unit, rather than assume a uniform policy.

What a review cannot do is rank these systems against each other in the abstract, because the right VirTis depends entirely on the batch and the product. A protein formulation group and a food research lab will reach for different shelf areas and different condenser specifications. The useful comparison is not which line is best but which one fits the run, and that is a reading of the specification against the protocol, listing by listing.

**Freeze drying across every scale**

VirTis builds lyophilizers from benchtop units to pilot and production systems, so a buyer can match the shelf area and condenser capacity to the batch size rather than over-specifying.

**A long installed base to draw on**

The Genesis, AdVantage and BenchTop lines have been in service for decades, which is why used VirTis equipment turns up on the secondary market with parts and documentation still traceable through Questpair.

**Priced below new, with condition stated per listing**

On Questpair every VirTis listing is used, and 100 percent of the catalogue carries a price set below what the equivalent new system costs.
