To select your glove size, measure (in inches) around your palm indicated by picture A. Lab Pro indicates glove sizes by letter (XS, S, M, L, XL, XXL), use the table below to find the equivalent translation.
Choose the letter size from the chart that is the closest to the number you measured. For example: if your hand measures 10", then choose a size "L"
To identify the correct glove length you need, measure from the top of the middle finger to where the cuff edge should be on forearm as shown in Picture B, then select the proper cuff and length.
Lab Pro offers three cuff lengths: 9", 9.5" and 12". The longer the length, the more added protection to your products.

Powder free Nitrile gloves are the most commonly used clean and reliable option for laboratory and cleanroom operators. While Latex is made from organic tree sap and contains allergy-causing proteins recognized by the FDA, Nitrile is manufactured from a 100% inorganic synthetic material. Nitrile gloves provide superior barrier protection, minimize the risk of allergic reactions and possess excellent electrostatic discharge (ESD) properties. Nitrile with its memory-membrane is the most common option for operator comfort. This feature allows a nitrile glove to adapt to each individual’s hand, improving motion and minimizing fatigue.
|Nitrile and Latex Characteristics Comparison|
|Particle Count||Extractable Count||ESD Properties||Dexterity||Chemical Compatibility|
Numbers of particulate matter (contaminants) that comes off the gloves, typically measured in a dry test. Nitrile has the lowest amount of particles, followed by PVC, and latex has the highest particle count.
The capacity of a glove to dissipate, or conduct a static charge to a ground. Both PVC and nitrile exhibit excellent ESD qualities. Latex is insulative.
Latex is a good choice for protection against acids. Nitrile has better resistance than latex to a broad range of chemicals and performs well with solvents and acids. PVC has poor acid and solvent based resistance and is best suited for a dry environment. Note: Thin-walled gloves are only intended for splash protection.
The amount of elements extracted from the gloves in an immersion test, generally measured in Parts Per Billion (PPB) or Grams per Square Meter (g/m2). 18 mega ohm DI H2O washed nitrile has the lowest ionic counts, followed by PVC and latex.
Latex gloves fit tight on the hand, but have no “memory” to conform to a specific hand shape. Nitrile’s memory (modulus) properties provide more comfort, but are lower in elasticity than latex. PVC has much lower dexterity and is recommended when tactile requirements are low.
The primary purpose of wearing gloves in a controlled environment is to minimize sub-micron particle contamination of the product or process from the user’s hands. Therefore, choosing the most appropriate glove is one of the most significant cleanroom consumable selections.

Known for its durability, comfort, and dexterity, Latex gloves are the most common material for gloves. Latex is ideal when high dexterity and tactile sensitivity is required. It provides excellent protection against contamination and chemicals such as alcohols, acids, and ketones. In some people, latex proteins may cause an allergic reaction for which nitrile gloves provide a good alternative.
Nitrile is the most common material for gloves used in for laboratory and cleanroom environments. Nitrile Gloves offers good dexterity and superior resistance to many types of chemicals. Compared to latex, nitrile is lower in particles, ionic extractable and non-volatile residues. Nitrile also has “memory” properties that adapt it to the hand for a more custom fit that reduces fatigue. It is three times more puncture resistant than latex, and it also provides protection against cutting and scraping. Static-dissipative properties make nitrile ideal for use in medical device manufacturing, microelectronics, and other similar dry controlled environments.
PVC Gloves better known as Vinyl is proven for its ESD properties, inherent cleanliness (low in both particles and ionic extractable), and low cost. These attributes make vinyl gloves ideal for use in medical, restaurant and hospitality industry. A PVC glove fit looser on an operator’s hand than latex or nitrile, which can reduce dexterity.
Cleanroom gloves are bagged and designed to protect both the operators and the products. The primary purpose of wearing gloves in a controlled environment is to minimize sub micron particle contamination of the product or process from the operator’s hands. Therefore, choosing the most appropriate glove is one of the most important cleanroom consumable selections.
