Draining Rack Manufacturers in India
In any active laboratory, washing and drying glassware is a constant task. Beakers, flasks, test tubes, bottles, and pipettes are cleaned dozens of times a day — and every one of them needs somewhere clean, safe, and efficient to drain and air-dry. A well-designed draining rack keeps your laboratory bench organised, prevents breakage from careless placement, and speeds up the drying process by allowing unrestricted airflow around the neck and body of each vessel.
Viscilabs is one of India’s most established draining rack manufacturers, supplying laboratories, educational institutions, hospitals, and industrial facilities across India and internationally since 1976. Headquartered in Ambala Cantt, Haryana, and operating as an ISO 9001:2015 Certified company, Viscilabs brings nearly five decades of manufacturing expertise to every product — including our widely trusted range of laboratory draining racks, draining baskets, and draining trays.
What Is a Laboratory Draining Rack?
A laboratory draining rack is a purpose-built plastic or metal rack used to hold washed glassware and labware in an inverted, upright position so that excess wash water drains away freely while the items air-dry. It is one of the most frequently used accessories in any laboratory and is essential for maintaining a clean, efficient, and contamination-free workspace.
Unlike general-purpose drying racks, laboratory draining racks are specifically designed to:
- Securely hold glassware of varying sizes — from small test tubes to large bottles and Erlenmeyer flasks
- Allow maximum airflow around each item to speed up drying
- Collect and channel drained water away from the bench surface, keeping the workspace dry
- Resist the chemical cleaning agents and detergents routinely used in laboratory washing procedures
- Maintain their structural integrity over years of repeated use without rusting, staining, or warping
Viscilabs draining racks are manufactured from high-grade polypropylene — a chemically resistant, durable, and easy-to-clean polymer that is ideal for laboratory environments.
Our Draining Rack Product Range
Viscilabs manufactures and supplies a complete range of laboratory draining solutions, covering racks, baskets, and trays to suit every bench size and glassware volume requirement.
Draining Rack (Type: VPW-1121)
Our flagship laboratory draining rack is an essential post-wash tool for any laboratory. The back plate features 20 holes into which adjustable pegs are securely tightened using screw-nuts, allowing the rack configuration to be customised to hold glassware of different sizes and orientations.
Key design features include:
- 20-peg adjustable back plate — accommodates test tubes, flasks, beakers, bottles, and more in inverted position for effective gravity draining
- Integrated bottom tray — all water draining from the glassware is collected in the base tray, keeping the bench surface clean and dry
- Drain tube outlet — water collected in the tray can be channelled away into a container or sink via a drain tube, maintaining a clean and safe bench at all times
- Non-corrosive polypropylene construction — this rack does not rot, stain, or rust, even with repeated exposure to laboratory detergents, acids, and solvents
- Durable peg-and-nut fixing — pegs remain securely in place during use but can be repositioned or replaced as needed
The Viscilabs draining rack is a staple of chemistry, biology, microbiology, and analytical laboratories — anywhere that glassware is washed and reused routinely.
Draining Basket (Type: VPW1094)
Our draining basket provides a versatile and space-efficient alternative for bulk washing and draining scenarios. Designed to hold multiple items simultaneously, the draining basket is ideal for laboratories that wash large volumes of smaller labware — such as test tubes, vials, Petri dishes, culture plates, and small bottles.
The open-mesh construction allows water to drain freely from all sides, while the basket’s firm structure prevents items from falling or shifting during the draining and drying process. Manufactured from chemical-resistant polypropylene, the draining basket withstands regular exposure to laboratory detergents and mild disinfectants.
Draining Tray (Type: VPW1168)
Our laboratory draining tray is a flat, shallow-walled polypropylene tray designed to sit beneath draining racks, baskets, or individual items of glassware to capture all draining water and prevent bench contamination. The draining tray provides a clean, contained draining surface that can be easily emptied and wiped down, keeping the laboratory bench safe and dry between washing cycles.
The draining tray is also useful as a standalone draining surface for larger flat labware items — such as Petri dish lids, staining trays, and shallow vessels — that cannot be easily placed on a conventional peg rack.
Materials & Design Advantages
All Viscilabs draining racks, baskets, and trays are manufactured from polypropylene (PP) — the preferred material for laboratory plasticware used in post-wash applications.
Why polypropylene for laboratory draining racks?
Polypropylene is selected for laboratory draining equipment for a clear set of practical reasons. It is highly resistant to the broad range of detergents, surface disinfectants, and mild chemicals routinely used in laboratory glassware washing. Unlike metal alternatives, it will not rust or corrode when exposed to water or cleaning agents — making it a far more hygienic and longer-lasting option for environments where repeated wet exposure is unavoidable. It is also significantly lighter than metal racks, making it easier to reposition on the bench or transfer between workstations.
Polypropylene is dimensionally stable, meaning the rack holds its shape and rigidity over years of use without warping, cracking, or deforming. It is easy to wipe down or surface-clean with standard laboratory disinfectants. And because it is entirely non-reactive with common laboratory liquids, there is no risk of the rack contributing to cross-contamination of washed glassware.

Applications — Where Viscilabs Draining Racks Are Used
School and College Chemistry Laboratories — Draining racks are daily-use items in school and college labs where test tubes, beakers, and conical flasks are washed and dried between experiments. Our racks are robust, easy for students to use, and maintain their integrity through years of heavy classroom use.
University Research Laboratories — Research labs often work with high-value glassware that must be kept in pristine condition. Proper post-wash draining and drying prevents water spot contamination and physical breakage from improper stacking.
Pharmaceutical Quality Control Labs — Pharma QC labs are strict environments where cross-contamination prevention is critical. Dedicated draining racks ensure that washed glassware dries cleanly and is stored inverted, reducing the risk of contamination from airborne particulates settling inside vessels.
Microbiology and Clinical Laboratories — In microbiology, properly drained and dried labware is essential to prevent carry-over contamination between experiments. Draining baskets are particularly useful for bulk processing of culture tubes and small vessels.
Hospital and Diagnostic Laboratories — Clinical labs wash and reuse a large volume of small labware items daily. Our draining racks and baskets streamline post-wash workflows and maintain organised bench space.
Industrial and Environmental Testing — Industrial QC and environmental labs process large batches of sample containers routinely. Our draining rack range handles high throughput requirements reliably and with minimal maintenance.
Quality Assurance
Viscilabs’ quality management system ensures that every draining rack, basket, and tray that leaves our facility meets consistent standards of material quality, dimensional accuracy, and functional performance.
Our QA process for plasticware includes raw material incoming inspection to verify polymer grade and quality, dimensional checks on moulded components against design specifications, functional testing of adjustable peg fittings and drain tube interfaces, and visual inspection for surface finish, colour consistency, and absence of moulding defects.
The result is a draining rack that looks, fits, and functions correctly from the moment it is installed in your laboratory — and continues to do so reliably over its working life.
