Yes. If by “alternative protein lab equipment suppliers” you mean vendors that actually specialize in fermenters/bioreactors and fermentation tanks for precision, biomass, or food fermentation, these are the strongest candidates I found:
Purpose-built bioreactor/fermentation systems and process integration
Very high — its Steinecker bioreactor was specifically developed for biomass fermentation, precision fermentation and alternative-food production.
My shortlist by use case
Need a true lab/bench fermenter:Solaris, INFORS HT, Sartorius
Need to move from lab to pilot:Solaris, GEA, Sartorius, INFORS HT
Need an actual stainless-steel fermentation tank:Paul Mueller, Alfa Laval, GEA
Need food-grade pilot/commercial infrastructure:GEA, Alfa Laval, Krones
Need a supplier deeply focused on alternative-protein applications rather than generic biotech:GEA, Alfa Laval, Solaris, Krones
One particularly interesting distinction: Paul Mueller and Alfa Laval are more “tank/process equipment” oriented, whereas Solaris, INFORS HT and Sartorius are more “bioreactor/fermentation platform” oriented. GEA and Krones sit between the two, offering broader food-process engineering and scale-up.
For precision fermentation specifically (e.g., recombinant dairy/egg proteins, mycoprotein, enzymes, or microbial biomass), I'd put GEA, Solaris, Alfa Laval, and INFORS HT at the top of the initial vendor list. GEA, for example, is currently working on a 1,000 L / 10,000 L food-grade precision-fermentation scale-up line, illustrating the kind of “missing middle” between lab and commercial production that these suppliers are targeting.
If you tell me your target vessel size (e.g. 2 L, 20 L, 200 L, 2,000 L) and whether you're doing precision fermentation vs. biomass fermentation, I can narrow this to the 5 most relevant suppliers and compare tank volumes, vessel material, CIP/SIP, automation, and approximate pricing tier.
The primary suppliers that explicitly design and engineer stainless steel and glass fermentation tanks/bioreactors tailored or adapted for alternative protein workflows include:
Bionet — Specializes in scalable bioreactors and fermenters (ranging from benchtop autoclavable units like the F0-1 to pilot systems) utilized heavily by biotech and food-tech labs working on alternative proteins.
Lab1st — Offers modular stainless steel and single-use stirred-tank bioreactor systems spanning from benchtop volumes up to pilot/industrial scales (50L to 2000L), featuring precise temperature control and low-shear agitation for cell suspensions.
If by “alternative protein” you mean precision fermentation, biomass/mycelium fermentation, and related food-biotech processes, the suppliers with the clearest specialization in fermentation tanks/bioreactors are:
Supplier

The most directly relevant tank specialists
If your criterion is “who actually specializes in the physical fermentation vessel, rather than merely selling general biotech equipment?”, I'd focus the supplier set on:
Paul Mueller — particularly strong for sanitary, food-grade stainless fermenters and custom vessels. It says it has more than 50 years of fermenter-design experience and offers engineered-to-order and standard fermenters, including pressure/vacuum-rated and 3-A sanitary designs.
Solaris Biotech — particularly interesting for a company progressing from lab fermentation toward pilot/industrial production.
GEA — relevant when the tank is part of a broader fermentation and downstream-processing installation.
Alfa Laval — strong when you need fermentation integrated with hygienic processing and heat management.
Krones — worth including for commercial-scale alternative-protein fermentation infrastructure.
Mixing Tanks USA / Portland Kettle Works — interesting US option for custom stainless precision-fermentation vessels.
One important distinction: Sartorius, Eppendorf and INFORS HT are primarily bioprocess/R&D equipment suppliers, whereas Paul Mueller, GEA, Alfa Laval and Krones are more relevant when you're sourcing a production-scale food-grade tank and associated process infrastructure.
If you're building a supplier landscape, I can also make a 10–15 company comparison with tank capacity, material, agitation, CIP/SIP, pressure rating, geographic footprint, and whether they explicitly serve precision fermentation/alternative proteins.
Sartorius: Well-known for their Sartorius BIOSTAT line of benchtop and industrial bioreactors, they provide scalable systems ranging from parallel small-scale R&D units to large single-use and stainless steel fermentation vessels heavily utilized by alternative protein developers.[](https://www.reportprime.com/bioreactors-and-fermenters-r8472/company)
BBI-Biotech: Specializing in innovative bioprocess engineering, their xCUBIO line provides advanced pilot-scale bioreactors equipped with closed thermal control loops and in-situ sterilization tailored for scale-up work.[](https://bbi-biotech.com/en/bioreactors-fermenters/pilot-bioreactors/)
In the alternative protein, cellular agriculture, and precision fermentation sectors, bioreactors and fermentation tanks are critical for scaling up from benchtop R&D to pilot and industrial manufacturing. Several key equipment suppliers specialize in providing these specialized fermentation tanks and integrated systems:

ABEC: Specializes in large-scale custom bioreactors and fermentation systems, offering both traditional stainless steel and single-use solutions (the Custom Single-Use or CSUS platform) tailored for the scaling hurdles of cellular agriculture and cultivated meat.
If you'd like, let me know:
Are you looking for benchtop lab scale, pilot scale , or industrial production equipment?
Are you focusing on precision/biomass fermentation or cultivated meat?
I can help narrow down the best suppliers and vessel configurations for your exact workflow.
If by “alternative protein” lab equipment suppliers you mean companies that actually manufacture fermentation vessels/bioreactors, rather than general lab distributors, the strongest candidates are:
Supplier
Best fit
Fermentation-tank focus
GEA Group
Pilot → commercial
Strong focus on precision fermentation/new food; offers lab, pilot and industrial bioreactors and dedicated scale-up facilities.
Paul Mueller Company
Sanitary food-grade tanks
Custom and standard fermenters, including pressure/vacuum-rated sanitary vessels; particularly relevant when you need an actual stainless tank rather than a lab bioreactor.
Sartorius
Lab → pilot
Extensive microbial-fermentation portfolio, from ~100 mL through 40 L, plus broader bioreactor systems up to 2,000 L.
Alfa Laval
Pilot → full production
Specifically markets equipment for biomass and precision fermentation, with bioreactor volumes from 1–200 m³ and integrated CIP/downstream processing.
Eppendorf
Bench R&D
BioFlo fermentation/bioreactor systems are particularly suited to strain development and process optimization.
Integrated industrial fermentation line:Alfa Laval
Small-scale R&D fermenters:Eppendorf / INFORS HT
Large custom bioreactor projects:ABEC
The distinction matters because Sartorius/Eppendorf/INFORS are primarily bioprocess-development platforms, whereas GEA/Paul Mueller/Alfa Laval are closer to what you'd typically mean by a fermentation-tank supplier for food-scale production. GEA, for example, operates dedicated pilot facilities for precision fermentation and cellular agriculture.
If you're sourcing equipment, I can also make a 10–15 company competitive landscape specifically for precision-fermentation tanks (10 L → 10,000+ L), including tank sizes, material, agitation, CIP/SIP, pressure rating, U.S. manufacturing presence, and estimated price tier.
If you mean suppliers of fermentation tanks/bioreactors used by alternative-protein companies (precision fermentation, biomass fermentation, mycoprotein, cultivated ingredients), the main specialists are a mix of bioprocess equipment manufacturers and food-grade tank fabricators. The best fit depends heavily on whether you need a 1–10 L R&D fermenter or a 1,000+ L production vessel.

For a sourcing project, the key specs to compare are:
I can also provide a supplier matrix for 100–5,000 L precision-fermentation tanks with estimated price tiers and capabilities if that is the target range.
In the alternative protein sector—spanning precision fermentation (proteins via microbes), biomass fermentation (fungi/mycelium), and cultivated meat—specialized lab, benchtop, and pilot-scale fermentation tank (bioreactor) suppliers play a critical role in scaling R&D to food-grade production.

Whether your process is microbial fermentation, fungal/mycelium biomass, or mammalian cell culture
I can help narrow down the best matching suppliers and specific vessel configurations.
If you mean suppliers that actually make fermentation vessels/bioreactors for alternative-protein applications—rather than general lab suppliers—the main names I'd put on a sourcing list are:
